Abstract
An information gathering mechanism efficiently acquires information about a path interconnecting a source node and a destination node in a computer network. The mechanism comprises a novel packet configuration for soliciting parameters pertaining to network characteristics from routers coupled to the path. This novel probe packet preferably has a flexible format so that it may be processed not only by routers configured to interpret this type of packet, but also those that are incapable of either supplying some of the parameters or, further, deciphering any of the contents of the packet.
