Abstract
The transport capacity of a Virtual Concatenation Group (VCG) can be reduced under control of a Link Capacity Adjustment Scheme (LCAS). The VCG comprises link members, in which payload data are transmitted. A first control message comprising a fail message (R) for a link member is transmitted from sink to source, while the sink continues reception of payload data. On reception of the first control message at the source, a second control message is transmitted comprising a message (F) indicating that payload data of the link member shall not be used, and transmission of payload data is discontinued. On reception of the second control message at the sink reception of payload data is discontinued, and the link member is removed. This allows a reduction of the transport capacity of a Virtual Concatenation Group to be performed in a hitless manner, even when initiated at the sink side.
