System and Method for Traffic Engineering Information Summary of a Zone in Network Communications

摘要

A method for summarizing topology transparent zone (TTZ) traffic engineering (TE) information, comprising computing a TE link state for every TE link internal to a TTZ from a root node to one or more non-root edge nodes, wherein the TE link state comprises the maximum bandwidth of the link, summarizing the computed TE link state information and storing the summary in a memory, and distributing at least a portion of the information in the summary to at least one neighboring node external to the TTZ connected to the root node via an external link.
