VPWS
Virtual Private Wire Services (VPWS) or Pseudo Wire Emulation
Edge to Edge (PWE3) provide point-to-point connectivity
between customer sites, where the service provider network
emulates a set of wires between the customer's sites over the
underlying MPLS tunnel.
This is particularly useful in the case where a customer is
currently using a set of ATM or Frame Relay connections
between their different sites, as the VPWS can emulate the
existing links. Customer can keep the same layer 2 connections
to the service provider, but instead of data being carried natively
over an ATM or Frame Relay service, the traffic is encapsulated
and routed over the provider's MPLS backbone.
VPWS makes the convergence of Layer 2 and Layer 3 services
possible over an IP/MPLS cloud. VPWS lets service providers
deploy point-to-point circuits with Ethernet as an attachment
circuit, allowing high-speed LAN connectivity. Mostly two
