What Is VPLS?
VPLS is a class of VPN or Virtual Private Network that connects multiple sites to form a single bridged domain. It is implemented using a MPLS or Multi-Protocol Label Switching Network. That makes it protocol-transparent so that all services, regardless of which location the are physically located at, appear to be on the larger LAN that serves all locations.
How Do You Connect to an MPLS Network?
Popular access connections are T1 lines, DS3 bandwidth, fixed location wireless, Ethernet over Copper and fiber optic services. In some cases, business grade DSL may also be used to save cost.
When Should You Use VPLS?
VPLS might be the right service for your company or organization if you need to connect anywhere from a few to a few dozen locations as if they were on a single Local Area Network. Advantages of this approach, compared to a private network arrangement with individual point to point connections back to headquarters, include lower latency, higher efficiency, and lower cost... perhaps much lower cost.
Can MPLS Offer VPN Services?
MPLS networks are inherently virtually private because they are a privately operated network that can only be accessed by network customers. Security is enhanced by proprietary tag switching routers that don't use standard IP routing. Encryption can be added to further improve data security.
MPLS Network Speeds
MPLS networks can run at any network speed and are being adopted by major carriers as the multipoint to multipoint technology of choice. For this reason, MPLS is fast replacing Frame Relay.
