>> We'll be having a first meeting of the proposed Path Aware Networking (PAN) RG at IETF 99 in Prague next week, 13:30 Wednesday in Congress Hall 3. Since bringing path awareness to the endpoint has been the focus, at least in part, of a couple of running TSV working groups (MPTCP, TAPS), this RG seems to be of general interest to the transport area.  Olivier Bonaventure will give a review and overview of research to date in this space, and Adrian Perrig will present a fully path-aware Internet architecture, as an illustration of what is possible when path-awareness is promoted to a first-order goal.
