Summary:Several technologies are coming together to make Ethernet compelling for metro access. Perhaps the most interesting is the combination of virtual concatenation (VCAT) and generic framing procedure (GFP) in the Sonet/SDH segment, along with the enhancements to Ethernet that make it "carrier-worthy." To leverage Ethernet in the metro, however, it's necessary to understand the existing Sonet/SDH infrastructure and how it can be adopted to take advantage of Ethernet more efficiently.
