IP Path Tracing BOF (ippt) Thursday, December 13 at 1300-1500 ================================== CHAIR: Craig Partridge DESCRIPTION: GOAL: Very low cost methods of storing packet trace information in routers and other devices along a network path have been recently developed. It is possible, using these technologies, to trace individual packets back to their source (see, for instance, Snoeren et al, Hash-Based IP Traceback, http://www.acm.org/sigcomm/sigcomm2001/p1.html). This BOF is focussed on the protocols required to support this kind of trace information and whether IETF wishes to standardize these kinds of protocols. AGENDA: * Ritual Agenda bashing and passing of the blue sheet * Brief presentation of hash-based traceback * Protocol requirements to support hash-based traceback * Intellectual property issues * Discussion of IETF role
