VPLS
VPLS builds on the VPWS point-to-point pseudowire model,
adding packet replication and the ability to learn source-based
MAC addresses for multipoint Layer 2 capabilities. It is an
attractive option for service providers because it uses a Layer 2
architecture to offer multipoint Ethernet VPNs that connect
multiple sites within a MAN or over a WAN.
Using VPLS, service providers can create a Layer 2 "virtual
switch" over an MPLS core. Enterprises with large, distributed
ERP applications and VoIP can benefit from these multipoint
services.
Users benefit from performance and connectivity that are on par
with a direct connection to a switch. This architecture for
providing geographically dispersed Ethernet Multipoint Service
(EMS) adheres to Metropolitan Ethernet Forum standards. Each
customer edge device or node communicates directly with all
other customer edge nodes in the EMS.
