Abstract:
1. A method for calculating a physical route for a currently established connection in a communication network comprising a plurality of nodes, each of the plurality of nodes having a plurality of ingress points and a plurality of egress points, the method comprising: retrieving information regarding the plurality of nodes from at least one of the plurality of nodes along a logical path for the connection; calculating which one of said plurality of ingress points is connected in the physical route of said connection for each of the plurality of nodes along the logical path; and calculating which one of said plurality of an egress points is connected in the physical route of said connection for each of the plurality of nodes along the logical path, wherein the calculating of the ingress point includes determining activation of protection schemes for the ingress point and returning a logical port as the ingress point if no protection scheme is activated.
