ABSTRACT:
Each node of a telecommunications network determines a connection type attributes available for each signal type supported by the node. Each signal type represents a different connection routing layer within the telecommunications network. Adaptation costs involved in traversing from one connection routing layer to another connection routing layer in the node are calculated. The connection type attributes and adaptation costs are included in a link state advertisement broadcasted by each node in the telecommunications network. A route calculation is performed for a desired signal to determine a route through the telecommunications network for the signal. The route calculation takes into account the various connection type attributes, availability, and adaptation costs in determining the shortest route for the signal through the telecommunications network.
