The present invention relates to an Explicit Routing Method used in a packet-based network containing a number of network-nodes, source-nodes and destination-nodes. All before mentioned network elements are interconnected by links. This method is used to route a packet-flow from a source node towards a destination node, along an explicit path through a number of these network- nodes. This method includes the step of determination of the explicit path of the packet-flow between the source-node and the destination-node. A subsequent step is the determination of the relevant intermediate network-nodes situated on the explicit path which are necessary to deviate said packet-flow from a hop-by-hop-path onto said explicit path and further adding only addresses of these relevant intermediate network-nodes to the packets of the packet-flow. A following step is forwarding the packet-flow from the source-node towards the destination-node in direction of the explicit path.
