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

IRIS

TCT6A VER 1.013
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.
7/22/2020
IRIS
ET
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.
