Apparatus, computer program and method of maintaining timely topology data within a link state routing network

摘要

An apparatus and method of forwarding a first message from a source to a destination via a link state routing network utilizes point-to-point feedback messages when the quality of a first path from the source to the destination meets some prescribed condition. To that end, the first path is initialized within the link state routing network. A feedback message relating to a first path having a plurality of data for updating a source database is received as a point-to-point message that is forwarded to the source. In response to receipt of the feedback message, the source database is updated.
