SDH/SONET Concatenation Strategies
	Contiguous concatenation (CCAT) Contiguous concatenation (CCAT) is a mechanism, which allows container concatenation by means of invers multiplex of STS / VC containers.	0	0	No Posts
	Virtual Concatenation (VCAT) Virtual Concatenation (VCAT) is a mechanism, which allows virtual container concatenation of arbitrary size by means of X.86 or Generic Framing Procedure (GFP) protocols in order to map payloads of arbitrary bandwidth into the virtually concatenated container.	0	0	No Posts
	Link Capacity Adjustment Scheme (LCAS) Link Capacity Adjustment Scheme (LCAS) is a dynamic concatenation scheme for virtually concatenated containers. Its dynamic character allows for adjustment to short-term bandwidth needs of network.	0	0	No Posts
	Generic Framing Procedure (GFP) Generic Framing Procedure (GFP) is the upcomming protocol for asyncronous data packet transport over any media (including dark fibre).	1	1	Wed May 10, 2006 5:11 pm knoll
