| 摘要 |
The invention is related to a method in a communication network for handling traffic, such as data packets, from source nodes to destination nodes, via user selectable relay nodes. The relay nodes form an overlay network of nodes operated and managed by an overlay network operator. Communication between relay nodes relies on using packet forwarding services of intermediate networks being operated and managed independently by other operators. For any source/destination pair the overlay network operator may select an appropriate sequence of relay nodes to be passed depending on the required quality of service and the performance of different intermediate networks. The invention enables the control of the spreading of traffic between any two end-points over several alternative relay routes. <IMAGE> |
