CCAG

cross-connect aggregation group

VSM-CCAs are placed in a CCAG. A CCAG provides a mechanism to aggregate multiple CCAs into one forwarding group. The CCAG uses conversation hashing to dynamically distribute cross-connect traffic to the active CCAs in the aggregation group. In the event that an active CCA fails or is removed from the group, the conversation hashing function redistributes the traffic over the remaining active CCAs within the group. The conversation hashing mechanism for a CCAG is identical to that used by Ethernet LAGs.
