Abstract

The invention concerns a method for service named routing in a packet based communication network (1) as well as a corresponding router (N, N2, N3). The communication network (1) comprises at least two servers (S1, S2) providing at least one service and a plurality of routers (N1, ..., N9). Each router provides a routing table (6), a service performance table (5) and an interest route table (7). Each router stores in its routing table for each service at least one connection port and in its service performance table for each service service performance data associated with its two or more connection ports (NI). A first router (N3) sends to neighboring routers (N1, N2, N4, N6, N7) via two or more of its connection ports (NI) an interest packet associated with the at least one service comprising a service name indicator (3a) and a unique interest tag (3b). A second router (N2) receives the interest packet via an incoming connection port, sends the interest packet via an outgoing connection port to a server (S1) of the at least two servers and stores the interest tag together with the incoming and outgoing connection port in its interest route table. The server (S1) attaches data comprising load data of the at least one service to the interest packet and sends the interest packet back to the second router. The second router calculates service performance data based on the data attached, stores the service performance data in its service performance table and updates the routing table based on an evaluation of the service performance data, and sends the interest packet via the incoming connection port as associated by the interest route table to the first router (N3).
