OPTIMAL SUMMARIZATION FOR PATH COMPUTATION ELEMENT (PCE) CONCEPT

摘要

The present invention provides a method, apparatus and computer program product for the optimal summarization of the path computation element (PCE) concept. The present invention includes composing, at a first network node, a request message including a request for domain summarization information from a second network node, the request message being capable of requesting the second network node to provide domain summarization information with respect to at least two criteria, and transmitting, by the first network node, the request message to the second network node.
