The present invention relates to communication field, wherein an embodiment of the invention discloses an ECMP path soft
recovery method in a MPLS-TP packet transfer network. The embodiment of the invention comprises the following steps: realizing functions of congestion discovering, congestion positioning, etc. by the expanded OAM information; transmitting TDM grouping dynamic
clock by MPLS-TP for adjusting operation; path
cracking of the bypass heavy routing; when congestion occurs, firstly adjusting TDM service data grouping length through a source end for improving the
delay characteristic; adopting a local service for
shunting to the service with overhigh speed for steering clear of the congestion routing; if local link resource is insufficient, informing the source end for adjusting the
bandwidth allocation, allocating higher bandwidth resource on the other N-1 paths; if no enough resources can be allocated or the allocated resources are not adjusted under the principle of simplifying the operation, informing the routing module by the source end, and completing the calculation of the other routing through the mode of incremental computation according to the bandwidth request amount. The method of the invention reduces the time for recovering
network congestion. The network flexibility can be enhanced through the mode of self-adapting grouping variable-length transmission, and the using efficiency of the protected resource is increased. The quick
performance recovery of the service is realized through the mode of bypass heavy routing
cracking. The quick combining operation at the branching point is completed with a special
numbering and a
signaling process.
