The Virtual Private LAN Service uses the MPLS network as a transport network and connects local networks via the MPLS WAN. From the point of view of the networked Layer 2 devices, the Virtual Private LAN Service and the underlying MPLS network work like a LAN switch on Layer 2 of the ISO/OSI reference model. Protocols other than IP can also be transmitted via the Virtual Private LAN Service. The Ethernet multipoint connectivity is implemented in the MPLS network. LDP (Label Distribution Protocol) or BGP (Border Gateway Protocol) signal the connections.

The basic operation of MPLS The Virtual Private LAN Service is based on Multiprotocol Label Switching (MPLS). MPLS is a network technology that routes (switches) data traffic on a connection-oriented basis based on predefined paths and labels. The routing decisions are no longer made individually in each IP node than in a connectionless IP network. Routing calculations are only performed once. The labelled data packets then move along the established paths. The labels are part of the four-byte MPLS header. In the OSI reference model, multiprotocol label switching moves between layer three and Layer 2.

MPLS works connection-oriented and allows the transport of IP data traffic with high performance and guaranteed quality parameters. MPLS is not limited to IP and can transmit other protocols. The basic functioning of the Virtual Private LAN Service To explain the basic functionality of the Virtual Private LAN Service, first, an explanation of the two terms PE and CE. CE stands for Customer Edge and designates the system component connected to the MPLS network on the user side (customer side). For example, in the case of VPLS, a CE device is a Layer 2 switch.

The MPLS network and the Virtual Private LAN Service behave transparently for the CE device. The CE device does not have to meet any VPLS-specific requirements and, from its point of view, connects via a switched LAN. The CE devices are connected to provider edge nodes (PE nodes). PE nodes are label edge routers (LER) or ingress and egress label switch routers (LSR). The PE nodes are located at the edge of an MPLS network. VPLS offers Ethernet multipoint connectivity in the direction of CE and maps the full mesh within MPLS using virtual connections and switched label paths. The virtual relationships can be signalled via protocols such as BGP or LDP.

When a PE node receives a LAN frame from a CE device, it checks the MAC destination address of the frame and, with an appropriate label, transmits it via a defined path to the desired destination. Frames with unknown destination addresses or broadcast frames are flooded to all PE nodes of a VPLS mesh. To avoid loops, a split-horizon PE never forwards a frame received from a PE node to a PE node. The label switch routers (EP nodes) are responsible for forwarding the labelled data packets along the established paths within the MPLS network.

Advantages of using the Virtual Private LAN Services The use of the Virtual Private LAN Services offers advantages such as:

• Establishing Layer 2 LAN multipoint connectivity over an MPLS WAN.
• Fully transparent LAN service from the point of view of the CE devices.
• Automatic rerouting within the MPLS in the event of an error – faster failover mechanisms than, for example, the spanning tree protocol.
• Different Layer 2 VPNs and other services can be implemented and operated simultaneously on an MPLS network.
• Flexible allocation of bandwidth and prioritization of traffic.

The SIM injector is PoE – capable so that no additional PoE switch must be attached when used. Together, the MAX HD1 Dome 5G and SIM injector are designed to simplify the setup and management of installations greatly. This extension can be placed up to 100 meters from the router and controlled via InControl2, which means that switching between different SIM cards and thus mobile phone connections can be handled flexibly and efficiently.

If several MAX HD1 Dome 5G devices are connected to a SpeedFusion-enabled router, the bandwidth is exceptionally high, according to Vitel. With the help of SpeedFusion, Peplink’s bandwidth bundling technology, it is possible to create a large VPN channel for a fast, reliable, location-independent Internet connection. The router is particularly suitable for mobile outdoor applications, for example mounted on a vehicle roof or a ship’s mast. Even on the go, the connection doesn’t break down, no matter how poor the network coverage is in some regions or on the high seas.

Uncomplicated commissioning with one cable The MAX HD1 Dome 5G can be mounted using an M35 bracket. Only an Ethernet cable is required for commissioning. The IP67-certified router, including shelves, is designed for harsh outdoor environments and is protected against splash water, dust, vibrations and adverse weather conditions. According to the IP rating, the router can even be underwater for up to 30 minutes. The cable is protected inside the router and should ideally be installed directly inside the pole or wall.

Reception via MIMO antennas 4×4 MIMO mobile antennas and a GPS antenna ensures that the signal quality and signal strength of the MAX HD1 Dome 5G remains as high as possible, regardless of the frequency range in which the signals are received. According to the manufacturer, the router is 11.5 centimetres tall, and the cross-section of the device is 22 centimetres long. Together with the Ethernet splitter, which weighs 500 grams, the total weight is 1.7 kilograms.

Within the proposals to update the corporate IT network, network virtualization and SD-WAN technology have allowed organizations to overcome the problems of complexity, physical limitations, and investment of time and effort that traditional networks demand.

With those two interlinked options, overlaying one or more logically separate networks on top of a single physical network, removing its time/space constraints. Network functions can be applied where and when they are needed. In the case of SD-WAN networks, an intelligent access layer recognizes the needs of each specific resource or service. It automatically routes it (following established rules) to a specific network to guarantee high performance.

NaaS (Network as a Service) is one more step that proposes to take advantage of these new network paradigms by contracting them as services in the cloud through a subscription. Let’s see what it consists of.

Keys To Choosing A NaaS Provider

Within the initiatives to update the network to advance companies’ digitization, the network as a service joins the multiple proposals for cloud infrastructure and software offered by cloud technology providers. The growing interest in this cloud network model is understandable since a good part of its components can already be consumed as a service.

Specifically, NaaS means hiring a service that offers everything you need to deploy a network and manage it; that is, hardware, software, licenses, and support. This package can be joined by its management as an IT-managed service. In addition, NaaS services incorporate cybersecurity solutions in a SASE environment (secure access services).

The success of this type of service depends on the NaaS provider that is selected and how its installation is planned and developed. Some of the issues that must be taken into account when choosing it are:

• Determine aspects whose measurement will give us the key to its quality. This is the case of bandwidth per user, activity times, the expected performance of applications, etc.
• Stipulate SLAs that define acceptable downtime.
• Ensure the frequency with which the resources that make up the network will always be updated to have technology that adapts to IT innovation and business demands.
• Know the conditions to escalate or reduce the contracted capacities.
• Know how capabilities and performance will be measured to assess the contracted service.

Benefits Of NaaS Services

The advantages of NaaS services are many. To begin with, the ease with which companies can deploy their network needs without having to make large investments at once or wait long times making and checking configurations. Added to this is that, as we have seen, they are based on virtualization and SD-WAN technologies; that is, they have access to an automated resource that perfectly meets the speed demands of cloud deployments, which is where they are primarily directing their IT resources.

With NaaS, it is easier to use multiple clouds, with the certainty that there is no need to develop specific structures for each of them according to their requirements. In addition, it allows the incorporation of cutting-edge communication technologies such as Wi-Fi6 to achieve high-speed connectivity.

Through a simple browser, it is possible to configure the network and link the desired points (dispersed offices, remote workers.), encrypting the communications between the different local or cloud resources used. You can apply the desired access management policy and receive all kinds of logs and reports on the activity of the network or networks. Its monitoring is continuous, which guarantees its performance and safety.

A Society Increasingly Connected To The Network

As we say, today we have many computers connected to the Internet. We are talking not only about computers and mobiles, but many other devices such as televisions, tablets, electronic books that also have a connection.

All this means that we are facing a society that is increasingly connected to the network. We have a wide range of possibilities that facilitate our day today. This undoubtedly adds value to the technology, as we have more functions and features.

But to ensure that all these devices that we mentioned are managed correctly we need a central team, an administrator. That’s where the router piece comes in. It is used to manage connections, to be able to offer the Internet to other computers safely and efficiently.

However, not all are the same, as we have mentioned. Times change and so do the appliances we use and the needs we create. That’s where the Smart or intelligent routers emerge, which offer us different functions and characteristics.

What Is A Smart Router

A Smart router offers additional functions to the traditional ones. That is, we do not manage the connections simply from the router panel, it has greater optimization and characteristics for the day-to-day of the users and the current times.

For example, an intelligent router allows you to manage the users who are connected from your mobile, to be able to eject devices from the network, to control how long a computer browses, etc. It allows you to have greater control regarding security, a factor that is so important. We can manage the keys intelligently, choose which computers connect or not, etc.

But also improve the management of Internet coverage and speed. It may be that a certain computer requires more speed at a given time, more resources to function properly. A smart router allows you to better manage the way you offer the Internet to other connected computers.

We already know that having a good Internet speed, a stable connection that does not have failures is something essential for all types of users. However, sometimes we can have problems and much of the fault is with the configuration of the router. That is where this type of equipment comes into play, which can better manage the connections to reduce problems to a minimum.

This type of device arises mainly from the needs of users. And it is that we have more and more devices that require greater management, more adequate control, and tools that also allow us to improve connections. In this way, we can gain security, stability, and of course speed. In the end, the sum of everything is what makes a product have higher quality.

The Rise Of IoT Devices

But all this we mentioned has the main reason: the rise of IoT devices. We have more and more computers connected to the Internet in our homes. They are very varied devices, which can range from smart bulbs to refrigerators, through televisions or video players.

All these computers are connected to the Internet and will need a router. These smart routers are the ones that are going to offer a greater range of possibilities and are going to create new functions so that connections flow correctly.

Modern routers have changed a lot from the ones we used a few years ago. They have more features to manage all connections, more possibilities to improve speed or performance.

In short, we can say that Smart routers are already part of the present, but they will be even more important in the future. The rise of the Internet of Things devices leads to the need for more resources for our day today.

Above all, poor performance annoys visitors and potential customers. You cancel streaming or online purchases: According to the Limelight Network State of Video Streaming from 2019, almost every second user leaves a website with a loading time of more than five seconds. Around 43 percent of the respondents even completely turned away from the provider and went to the competition.

Businesses have many opportunities to improve the online user experience. Above all, this includes a content delivery network ( CDN ) provided by a partner. But when it comes to displaying content, not all providers deliver the same performance and service quality. These factors depend on different aspects – such as cache capacity, latency, throughput, availability, and range.

The selection depends on key criteria such as the use of private connections: many providers rely too heavily on the best efforts of the public Internet for online streaming services or use too many to transfer data packets to the last mile provider Intermediate stations (hops). A private backbone with a global reach is more flexible and reliable than the public Internet and therefore preferable. It has high-performance points of presence (PoPs) in populous centers around the world and is based on peering agreements with all major Internet service providers.

Security is just as important. Given the increasing Internet risks, online providers need cloud services for a multi-layer defense against cyber attacks. On the one hand, you have to be able to rely on the fact that distributed denial of service (DDoS) attacks that affect availability are quickly identified and averted. On the other hand, it is important to distinguish and filter out authorized access to offers from unauthorized ones. A strong network wards off dangers without generating new latencies and thus impairing the performance of the web applications and the provision of the content. An integrated web application firewall (WAF) or capacities for bot management also protect against hacking attacks.

1. Increase Performance Holistically

Many companies assess the performance of a website primarily based on the loading speed. But this is only a factor, albeit a very important one. However, other key figures also influence the function and thus the evaluation by the customer. In the case of videos, the repeated caching in particular causes frustration. The user is also annoyed by the waiting time until more information is displayed or new items are added to the shopping cart. For example, throughput is important when downloading a new product. Good network providers, therefore, optimize several performance parameters to provide content in the best possible way and regardless of where they are or the device used.

2. Perform Content Audits

Most websites consist of a mix of static and dynamic content as well as small and large objects, such as videos. An audit can provide information about possible bottlenecks. When auditing a mobile website, for example, it turns out that it updates numerous dynamic thumbnails with every query. This results in a back and forth between the website and Origin. The system is overloaded and the delivery is delayed. However, the switch to on-demand video files often suggested here by CDN operators is not a suitable solution.

3. Intelligent Buffering And Retrieval

Many providers save frequently requested content on different network edges to be able to provide it faster. But even less frequently requested items can be called up quickly if required. Anything that cannot be found in the cache must be queried from the storage hierarchy or Origin Storage. A good network, therefore, uses intelligent caching software and hierarchical caching techniques and reduces the necessary access to the origin.

4. Optimize Origin Storage

The structure of Origin storage is often neglected. This has a direct impact on the workflow. Poorly integrated storage can make managing large libraries difficult. The inefficient selection of storage locations and slow transmission on the one hand delays the provision of the content. On the other hand, accessing the origins increases access costs. Under certain circumstances, these can even exceed the storage costs.

With an Origin Storage designed for serving inquiries, the offers can be better managed. Storage automation and intelligent services contribute to this. In this way, companies can better control their videos, games, or music and determine where and how they are fed in, stored, replicated, and delivered. For a faster query, we recommend solutions that enable automatic multi-regional replication of the files: A film or a game is automatically provided from the fastest available storage location.

5. Private Instead Of Public

Most CDN network providers still rely on public Internet connections. However, the associated, mostly unpredictable bottlenecks, reduced performance, latencies, and packet losses can affect the deployment. Interim storage at the network edges only helps in part. And what was not kept in stock poses a risk to availability. Companies should, therefore, choose networks with a private, quality-of-service-capable (QoS) backbone. This is the only way to ensure the secure, high-performance transfer of all content in the event of a cache miss.

Conclusion

In general, a CDN provider is not just a service provider that provides capacity, but a solution partner and consultant. You should, therefore, check whether he has the appropriate skills. So you can ask the provider questions in advance – about his experience and proven integration competence, about the successful improvement of the user experience, or the rationalization of processes. The available service naturally plays a special role. It must be clarified in advance how the CDN partner can help in an emergency. The minimum is always available telephone support. Because only fast help avoids high costs in the event of downtime.

The abbreviation ANDSF stands for Access Network Discovery and Selection Function. It is a standard of the 3rd Generation Partnership Project (3GPP). It provides mobile telephony providers with procedures to outsource the data traffic of mobile devices such as smartphones to access networks with other wireless network technology such as Wi-Fi networks or WiMAX networks.

This outsourcing is referred to as traffic offloading or mobile traffic offloading and is intended to avoid overload situations, improve the network supply to end customers, and reduce infrastructure costs for providers. ANDSF provides the end devices with, among other things, the rules (policies) for changing networks and provides information about the available alternative wireless networks. Both terminal and network-initiated changes are supported. In addition to ANDSF, other technologies, processes, and standards are defined for traffic offloading, such as Hotspot 2.0 for automatic login and authentication in Wi-Fi networks.

Basics Of Traffic Offloading

The term traffic offloading describes the idea and the necessary procedures to outsource data traffic from 3G, 4G or 5G– based mobile networks to alternative access networks with wireless technology such as in Wi-Fi networks. The goal of traffic offloading is to relieve the pressure on mobile phone networks and to avoid traffic jams caused by too many end devices and excessive use.

Mobile phone providers have the advantage of improving their customers’ network coverage without having to invest in additional mobile phone infrastructure and radio frequency licenses. Depending on the method used, offloading can in principle is triggered by the end device, the network, or the provider.

The mobile phone providers are pursuing the strategy of automating traffic offloading. Ideally, it should take place unnoticed for the user without interaction or intervention, and disconnection. This gives the providers maximum control options for the distribution of traffic flows and traffic loads. To implement seamless traffic offloading, standards such as ANDSF (Access Network Discovery and Selection Function) or Hotspot 2.0, also called Passpoint, were developed by various organizations.

How Access Network Discovery And Selection Function Works And Components

ANDSF uses the client-server model for communication between the end device and the network. The ANDSF client, also called user equipment (UE), communicates with an ANDSF server via OMA-DM (Open Mobile Alliance Device Management). Typical end devices are, for example, smartphones with iOS or Android operating systems.

The S14 interface is used as the interface for communication. The IP- based interface supports both push and pulls mechanisms. With the pull method, the UE contacts the server and requests information and rules for the network change. The push method communicates the policies to the UE without a specific request from the end device.

ANDSF can be used to transmit a list of available Wi-Fi networks within range of the end device. Also, information such as supported access technologies, network frequencies, and network identifiers such as SSID can be transmitted. ANDSF knows an Inter-System Mobility Policy (ISMP) and an Inter-System Routing Policy (ISRP), which can be communicated to the UE depending on the type of device. ISMP contains rules for end devices that only support an active network connection. The rules relate to the offloading of all terminal traffic. ISRP is intended for end devices that can operate several active network connections at the same time. This makes it possible to distribute traffic to different access networks via ISRP.

Advantages Through The Use Of Access Network Discovery And Selection Function

Traffic offloading with Access Network Discovery and Selection Function offers numerous advantages for both mobile operators and users.

These Advantages Are:

• Intelligent, seamless offloading to Wi-Fi networks without user interaction and disconnection.
• The comprehensive set of rules for changing networks can be implemented.
• Different information options for the end devices – push, pull, time-based, location-based.
• Manufacturer-independent standard – support of different network and end device technology with different operating systems.
• Automatic selection of the optimal access network.
• Reduction of the energy consumption of mobile devices by using local Wi-Fi hotspots.
• Avoidance of congestion and congestion in the cellular networks.
• Improved network coverage for mobile phone users – better radio coverage of areas with high user density or in buildings.

Wi-Fi Quick Check

A valuable first step is to do a brief analysis of your situation. To help you, there are useful analysis tools such as the Ekahau HeatMapper, recommended by experts. This program allows you to start creating a floor plan of your house to later measure the level of Wi-Fi coverage.

Position The Router Correctly

Is your WiFi too slow or does the connection stop completely too often? This is mainly due to a range problem since in many houses the router is located in a corner. Ideally, place it in a central, slightly elevated position, such as on a table or closet in the middle of the house. Also, the router should not be blocked by other objects in front of or next to you. If your router has external antennas, they can be oriented at different angles, and you can try various positions until reception improves.

Is The Router Too Old

If you have to replace your old router, the new model should support the new Wi-Fi 5 (Wi-Fi ac) standard, which is considerably faster than Wi-Fi 4 (Wi-Fi n). Furthermore, a part of Wi-Fi 4, the 2.4 GHz band, is extremely overloaded in many urban areas.

Your Wi-Fi will regain speed again by switching to the 5 GHz band of the Wi-Fi 5 standard. However, this only works if Wi-Fi receivers such as a smartphone, laptop, or tablet are also Compatible with the new Wi-Fi 5 standard.

Wi-Fi Repeaters For Short Distances

On large floors or single-family homes, there may be long distances, walls, or even reinforced concrete ceilings between the router and the Wi-F receivers. These obstacles act as a brake on the Wi-Fi signal, which becomes increasingly slow and, in the worst case, is completely lost. Using a Wi-Fi repeater is useful for shorter distances, such as from one room to another. However, it is not suitable for large homes because repeaters also use the Wi-Fi network for data transmission between them.

Internet From The Socket

Powerline adapters are a great solution for a good connection. The trick: they use the house’s electrical circuit as if it were a long data cable. The advantage: Walls, concrete ceilings, and even underfloor heating systems are no longer an obstacle because the solution is cable based.

Powerline WiFi adapters plugged into any electrical outlet create a fast internet access point with 100% speed. Also, installation is very simple: just plug in the adapter, wait a few moments, and start browsing. Today’s models combine the best of Wi-Fi technology with the fastest Powerline technology.

GSLB according to the DNS protocol is considered to be quick and reliable. Responses are almost real-time – an ideal option for applications that require high data center availability for disaster recovery.

As companies GSLB, they still face the challenge of quickly and reliably delivering applications to multiple locations while ensuring latency in DNS resolution, so it is advisable to use load balancing at the network level – including “Edge DNS-GSLB” called.

The digital infrastructure does hard work every day. It provides the responsiveness and availability that business applications rely on that are located in a wide variety of data centers (on-premises, in private or public clouds) and that are accessed from worldwide locations. The Gartner analysts study “Why Organizations Choose a Multicloud Strategy” found that 81 percent of respondents are currently working with two or more cloud providers. This means: Modern IT teams have to guarantee reliability more than ever in an ever-growing multi-cloud environment to keep business-relevant workflows going.

Smart Applications Require Load Balancing At The Edge

Load balancers and application delivery controllers (ADCs) are now well-known tools for balancing server loads. While ADCs distribute traffic within a single data center, the strength of the Global Server Load Balancer (GSLB) is that workloads are distributed across multiple data centers or locations.

Global server load balancers, which are integrated into recursive DNS servers and are used at the edge of the network, ie “at the edge” (Edge DNS GSLB), take this approach to a new and more sophisticated level. Benefits include simplified deployment, improved user experience, more robust applications, and, what may be very important for some companies, optimized disaster recovery plans (DRP).

This means that they are more fully and better prepared for potential system failures and can, therefore act more relaxed. The combination of DNS and GSLB functionality on one server significantly reduces capital expenditure and operating costs and simplifies the rollout in the entire company infrastructure.

The Benefits Of Global Load Sharing

By implementing GSLB in recursive DNS servers, traffic routing decisions for applications can be made geographically closer to the user and thus enable native localization. Since GSLB can be used at remote locations, the reliability is additionally strengthened. At the same time, the possibility of error detection on data center, WAN, server, and GSLB failures improves.

Large system failures at well-known companies repeatedly make it into the global media, as they can bring about numerous negative side effects such as damage to image and loss of sales. Incidents such as Google’s November 2019 cloud outage are rare but show that even the largest players in this area are not invulnerable.

DNS-based edge GSLBs can significantly minimize the impact of such an interruption since business-relevant data traffic can be seamlessly routed to a previously defined and configured backup data center at another location. Also, by adding IP Address Management ( IPAM ) capabilities, companies can manage both their cloud and on-premises applications from a central repository. For network administrators, GSLB facilitates system recovery at the network level in all three central steps of disaster recovery, preparation, testing, and activation.

1.Stress-Free Preparation

Changing the configuration of DNS records for multiple applications can turn out to be a confusing and complicated matter that also involves various sources of error. Edge DNS GSLB provides support here; because the technology approach can be used to prepare the respective failure scenario and, in a next step, simplify activation.

Global server load balancing at the network level, which is linked to an application repository, enables preparation at the server level, which is used in the event of a system failure. Administrators can plan and work out the priority defined in the Business Impact Analysis (BIA) for the changeover of each application without any stress.

2.Simplified Testing With Minimal Impact On Network And User

By relying on DNS to prepare for a system failure, IT teams prevent the entire network from being disrupted when testing their disaster recovery plans. You can easily test a DRP scenario at a pilot site and apply your recovery strategy on only one Edge DNS GSLB server without affecting other sites. This means that you can substantiate that your approach is robust and reliable and that user access to applications will not be affected.

3.Automated And Error-Free Switchover Activation

With just one click and using the Edge DNS GSLB approach, the configuration defined in the preparation phase can be implemented in an emergency. During the disaster recovery phase, the DNS configuration on all servers is automatically changed by switching the management status of the nodes per application priority. The application traffic is also routed to the services located in the backup data center.
