Abstract:
1. A method for controlling an establishment or modification of a connection in a communication network comprising a plurality of nodes subdivided into a core network and an access network, the connection comprising a plurality of connection stages, each connection stage controlled by one or more nodes, the method comprising the steps of: modifying or establishing at least a portion of the connection between selected nodes, one of the selected nodes being configured to employ one or more coding schemes along the connection, the coding schemes being selected from a plurality of supported coding schemes potentially affecting connection quality by individual amounts, and sending an indicator between the selected nodes including a node in the core network that includes information pertaining to the connection quality, wherein the indicator includes a plurality of individual values, each individual value corresponding to one of the supported coding schemes employed by one of the selected nodes and indicating an expected accumulated impairment associated with employing the one of the supported coding schemes at the one of the selected nodes, wherein a plurality of candidate paths with respect to individual concatenations of supported coding schemes lead through any preceding connection stages to a current connection stage.
