Ethernet Over SONET GFP, VCAT and LCAS
Overview Enterprise networks are demanding Ethernet services to their Service Providers. In a time when capital is constrained, Service Providers want to use their present SONET/SDH infrastructure to transport Ethernet in their access and metro networks. Three new technologies are emerging, which combine, can optimize SONET/SDH for data transport: the Generic Framing Protocol (GFP), Virtual Concatenation (VCAT) and LCAS (Link Capacity Adjustment). GFP provides a new and more efficient Layer 2 encapsulation scheme for data traffic over SONET/SDH. VCAT allows the logical concatenation of multiple SONET/SDH frames. Whereas, LCAS allows to right size those virtual concatenated paths. Together VCAT and LCAS allow SONET/SDH to better fit busty data traffic.
