A guide to designing and implementing VPLS services over an IP/MPLS
switched service provider backbone
Today's communication providers are looking for convenience,
simplicity, and flexible bandwidth across wide area networks-but
with the quality of service and control that is critical for
business networking applications like video, voice and data.
Carrier Ethernet VPN services based on VPLS makes this a reality.
Virtual Private LAN Service (VPLS) is a pseudowire (PW) based,
multipoint-to-multipoint layer 2 Ethernet VPN service provided by
services providers By deploying a VPLS service to customers, the
operator can focus on providing high throughput, highly available
Ethernet bridging services and leave the layer 3 routing decision
up to the customer.
Virtual Private LAN Services (VPLS) is quickly becoming the
number one choice for many enterprises and service providers to
deploy data communication networks. Alcatel-Lucent VPLS solution
enables service providers to offer enterprise customers the
operational cost benefits of Ethernet with the predictable QoS
characteristics of MPLS.
