  • Temporary disabling of a member of a Virtual Concatenation Group
    Patent number: 7684327
    Abstract: A member of a Virtual Concatenation Group (VCG) can be temporarily disabled under control of a Link Capacity Adjustment Scheme (LCAS). The VCG comprises a number of link members, in which payload data are transmitted. A management command (MLOCKOUT) is transmitted from a management system to at least one of the source and sink side for one member requesting the member to be temporarily disabled. In response to the management command a forward control message is transmitted from the source side comprising a message (FDNU) indicating that payload data of the member shall not be used, and transmission of payload data for the member is discontinued. In this way temporary disabling of a VCG member is provided, in which it is ensured that the same member is enabled again when the operation requiring the disabling is completed, and which can be handled as a separate function by the management system.

  • Reduction of the transport capacity of a virtual concatenation group
    Patent number: 7616558
    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 (RFAIL) 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 (FDNU) 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.
