LCAS: Link Capacity Adjustment Scheme

Link Capacity Adjustment Scheme (LCAS) is a method of using SONET/SDH overhead to communicate the status of a Virtually Concatenation (VC) connections. LCAS allows re-adjust of link capacity without traffic loss or network error. LCAS is a key enabler of Ethernet over SONET/SDH (EoS) networks. The LCAS mechanism can also automatically decrease the capacity if a VC/SPE in a VCG experiences a failure in the network, and increase the capacity when the fault is repaired.
