Virtual concatenation (VCAT)

•It is an inverse multiplexing technique creating a large capacity payload container distributed over multiple smaller capacity TDM signals

•These signals may be transported or routed independently. Virtual concatenation has been defined for SONET/SDH, OTN and PDH path signals

Link Capacity Adjustment Scheme(LCAS)

•Link Capacity Adjustment Scheme or LCAS is a method to dynamically increase or decrease the bandwidth of virtual concatenated containers

•The LCAS protocol is specified in ITU – T G.7042•It allows on-demand increase or decrease of the bandwidth of the virtual concatenated group in a hitless manner.

•This brings bandwidth-on-demand capability for data clients like Ethernet when mapped into TDM containers.

TCT6A VER 1.014

•LCAS is also able to temporarily remove failed members from the virtual concatenation group failed member will automatically cause a decrease of the bandwidth and after repair the bandwidth will increase again in a hitless fashion

•Together with diverse routing this provides survivability of data traffic without requiring excess protection bandwidth allocation.
