适用范围

This Recommendation specifies a link capacity adjustment scheme that should be used to increase or decrease the capacity of a container that is transported in an SDH/OTN network using Virtual Concatenation. In addition, the scheme will automatically decrease the capacity if a member experiences a failure in the network, and increase the capacity when the network fault is repaired. The scheme is applicable to every member of the Virtual Concatenation group. This Recommendation defines the required states at the source and at the sink side of the link as well as the control information exchanged between both the source and the sink side of the link to enable the flexible resizing of this Virtual Concatenated signal. The actual information fields used to convey the control information through the transport network are defined in their respective Recommendations, ITU-T Recs G.707/Y.1322 [1] and G.783 [3] for SDH and ITU-T Recs G.709/Y.1331 [2] and G.798 [4] for OTN.
