Ethernet has been widely deployed around the world in Local Area Networks (LAN) until now. Native Ethernet packet data increase over the LAN and Wide/Metropolitan Area Networks (WAN/MAN) has resulted in strong standardization efforts to use Ethernet as transport protocol. Metro Ethernet has evolved with the following attributes: standardized services, scalability, reliability, QoS, and service management.
MEF has defined several services:
• E-Line: Ethernet service that is based on a Point-to Point Ethernet Virtual Connection
• E-Lan: Ethernet service that is based on a Multipoint-to-Multipoint Ethernet Virtual Connection
• E-Tree: Ethernet service that is based on a Rooted Multipoint Ethernet Virtual Connection
In this paper you are required to compare the delivery of L2-VPN services over MEF based service definitions with MPLS based L2-VPN (VPLS). Your paper should consider the limitations and complexities of both approaches. The delivery of traffic engineering should also be covered and you are required to demonstrate and understanding of how TE is made possible using PBB-TE and MPLS-TE.
