Abstract:
A method of forwarding a first message from a source to a destination via a link state routing network, wherein the source and destination are nodes coupled by at least one intervening node, each node having associated link coupling characteristics, the method comprising:initializing a first path from the source to the destination via the link state routing network, including transmitting desired link coupling characteristics for the first path to each node in the first path; receiving a feedback message relating to the first path, the feedback message including data relating to a quality of the first path relative to the desired link coupling characteristics of the first path, the feedback message being a point-to-point message forwarded to the source; initializing a second path from the source to the destination in response to receipt of the feedback message by the source; and forwarding the first message to the destination via the second path.
