PROBE ROUTING IN A NETWORK

摘要

A method of network probing is described suitable for probing between a probe node and a destination node. The network comprises a further node which is connected to the probe node and the destination node. A node is typically selected to be a redirecting node and the routing rules at this redirecting node are bypassed by accessing further routing rules. A node is typically selected to be a forwarding node and packet forwarding is enabled at the forwarding node. A probe packet transmitted between the probe node and the destination node can travel via the forwarding node. The result improves network probing by allowing probing of links not otherwise available for probing from the probe node, but without the disadvantages of complex packet processing at each node in the probe pathway.
