Abstract
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 having data relating to a quality of the first path then is received as a point-to-point message that is forwarded to the source. In response to receipt of the feedback message, a second path is initialized from the source to the destination. The first message then is forwarded to the destination via the second path.
