It allows geographically dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires. Virtual private LAN service ( VPLS ) is a telecom carrier-provided service that makes it possible for customers to create a logical local area network structure between geographically separate sites. How do I create a VPN network? What is the purpose of a virtual private network?
Virtual private LAN service (VPLS) is a type of virtual private network technology that enables the connection of one or more local area networks ( LANs ) over the Internet through a single bridged connection. Full mesh requirement is for normal LVPN Architecture. The virtual private LAN service (VPLS) is an Ethernet-based point-to-multipoint Layer virtual private network (VPN) that enables you to connect geographically dispersed Ethernet local area network (LAN) sites to each other across an MPLS backbone. It does not offer much beyond VPN.
In this manner, the service virtually bridges the customer end-points, simulating a private LAN. Resiliency is also provided by the MPLS LSP and PW layers which can be considered to be independent of the VPLS service instance. Services are denoted in the same manner as for VPWS, as is CoS ID. Introduction Ethernet has become the predominant technology for Local Area Network ( LAN ) connectivity and is gaining acceptance as an access technology, specifically in Metropolitan and Wide Area Networks (MAN and WAN, respectively).
