Efficient Packet-Oriented Service Delivery with GFP/VCAT

Generic Framing Procedure (GFP) is defined by ITU-T G.7041 and ANSI T1-105.02 standards and is the BTI Systems approach to transporting IP, Ethernet, and Storage traffic efficiently and enabling simplified network interoperability. Framed GFP (GFP-F) is optimized for bandwidth efficiency encapsulating complete frames with a GFP header. Transparent GFP (GFP-T) is used for low latency transport of block-coded client signals such as GbE, Fibre Channel, and FICON.

Virtual Concatenation (VCAT) provides increased granularity to enable services to better fit client bandwidth requirements to allocated WAN bandwidth. This technology allows for increased WAN efficiency as well as expanded market applicability for connectivity services based on the ability to sub-rate bandwidth offers (ie: 300Mbps Gigabit Ethernet Private Line service).
