Abstract
Embodiments of the present invention provide a method for reducing the capacity of a Virtual Concatenation Group (VCG) and a VCG communication network. When a network management device sends a downlink-member removing command to remove a downlink member to a Sink in the VCG, the Sink receiving the downlink-member removing command in the VCG sends, to a Source, failure state information indicating that the downlink member will be removed; the Source receiving the failure state information in the VCG sends do-not-use information to the Sink indicating that the downlink member will not be used any longer, and the Sink removes the downlink member; the network management device sends an uplink-member removing command to remove an uplink member to the Source, the Source removes the uplink member which will not be used any longer. Thus, possibility of mis-operation can be avoided fundamentally and operational freedom of an operator is enhanced.
