摘要： An aspect of the disclosed technology is a process, apparatus, and/or system that provides a capability to automatically derive the bandwidth required for a given bypass tunnel, and use it to compute a compliant path across the network, without reserving bandwidth of a given bypass along its path. This may be implemented by computing (e.g., summing) the signaled bandwidth required of all MPLS LSPs supported by a given bypass tunnel. The computation may be done as part of bypass tunnel re-optimization or re-signaling, prior to the Constrained Shortest Path First (CSPF) algorithm or procedure being run by the PLR or periodically.
