Virtual Private LAN Service (VPLS) is a technology that makes available an Ethernet-based multiple point-point communication through IP/MPLS networks. This permits offices or buildings that are apart geographically to share the same Ethernet broadcast domain by connecting them via pseudowires. The technology allows the any-to-any connection.
In a Virtual Private LAN Service, the LAN at every site is extended to the edge of the provider of the network. The provider of the service then uses a bridge or a switch to connect all the users to the LAN and create a bridged LAN (single). The clients receive benefits of the jitter and the lower latency.
Having a mesh type of network, the user has a higher level of manageability as the changes in the network do not require the help of a carrier. The carrier will provide some online tools for management, allowing the users to view the hops in the networks up to the local loop. This makes it easier to troubleshoot the networks in case of any failures and problems.
Advantages
- Secure fast and homogeneous.
- Often costs way lower than the MPLS in terms of bandwidth and Mbps.
- Handles protocols.
- It is an easy to understand service if you that Ethernet.
- Lower latency
Disadvantages
- Everything that has advantages, as you would expect, has cons. There is nothing that can be perfect and free from all flaws. Depending on what you intend on using it for, the cons may be things that you can actually work around with ease.
- The carrier does not manage the networks but instead, the client does the managing themselves.
- It can be a complicated system to manage especially if there are many computers with Mac addresses and no hierarchy of any sort.
- It is not very scalable.
- Local loops of the Ethernet are not available in all parts of the world.
If the networks that you use require lower latency that you have and less packet loss, then VPLS may be something that you may want to delve into it and get more information.
Why you should consider it for your WAN
- You get more manageability and flexibility – companies that are able to respond fast to the changes in the market, then they will totally benefit them. VPLS use MAC addresses that have layer 2 switches unlike the MPLS (layer 3) that make use of layer 3 routing and IP addressing. This is advantageous as you will have complete control over your very own routing.
- More efficiency– Companies that have the VPLS enabled, will have a smoother running of their operations as they will be able to provide their customers with the best service. This is given the fact that companies can isolate network problems faster as they have access to their network information. The IT department can easily troubleshoot the problems and fix the urgent problems fast.
- Fewer costs -This is because VPLS enables companies to converge services such as video and VoIP so that all their traffic may be delivered in one Ethernet interface. This gets rid of the need to lease lines.
