Metro Ethernet technologies involve the use of carrier Ethernet in Metropolitan Area Networks (MANs). Metro Ethernet can connect company LANs and individual end-users to a WAN or to the Internet. Companies often use Metro Ethernet to connect branch offices to an intranet.
A typical Metro Ethernet deployment uses a star or a mesh topology with interconnected network nodes using copper or fibre optic cables. Using the standard and widely deployed Ethernet technology in Metro Ethernet deployments offers a number of advantages, as opposed to using SONET/SDH or MPLS technologies:
- Less expensive
- Easier to implement . . .
