Method and apparatus for providing fast spanning tree re-starts

摘要: The invention relates to a method and apparatus for rapidly re-starting spanning tree process at an intermediate device. A entity running one or more instances of protocol stores record parameter information port states in non-volatile memory. Following re-start, the verifies whether memory is still valid. If so, adopts device resumes forwarding messages accordingly. from no longer valid, discards it proceeds re-calculate transition its conventional manner.
