VPLS, a VPN based WAN Solution that is getting some well deserved attention.
Ten years ago, 80% of business data was generated and consumed internally, and only 20% external. Now, the ratio is reversed with 80% of data existing generated from external sources, a trend that is only going to increase with IoT. This shift changes how an enterprise CIO, CTO or network admin thinks about data and connectivity.
vXchnge and Cogent recently held a networking event to discuss the importance of high performance, low latency solutions for today’s multi-site and geographically dispersed organizations. Part of the discussion centered around the importance of the network edge, to help connect with consumers and other businesses locally in markets to help provide solutions ideas for the external data generation trends.
One of the topics was the best-practice ways to use Multiprotocol Label Switching (MPLS) vs Virtual Private LAN services (VPLS). MPLS can suffer from a variety of latency issues, additionally outing can also be a challenge. In some instances, when companies need local providers, the ones they find may vary in quality and routing policies, which can cause latency on their networks. In other cases, the local provider may have insufficient bandwidth which can cause congestion during peak loads.
While companies have relied on MPLS for years, VPLS has started to get more attention. VPLS is a newer type of VPN that allows multiple sites to be connected in a single bridge domain using a managed MPLS network. VPLS simplifies the boundaries between local and wide area networks where all devices look like they are running on the same ethernet LAN.
“VPLS uses edge routers that can learn, bridge and replicate on a VPN basis. These routers are connected by a full mesh of tunnels, enabling any-to-any connectivity,” according to Cisco.
Both MPLS and VPLS provide virtual private networking, any-to-any site communication, class of service, and IP support. Their difference include the number of sites they can support, methods of access, and IP routing control used.
Both MPLS and VPLS provide virtual private networks designed to meet the enterprise CIO, CTO or network admin’s any-to-any connectivity needs and will continue to co-exist in enterprise wide area network (WAN).
