It's been suggested The scope of this RG might be of interest to your working group, research group, or BoF, so I hope you'll have a chance to drop by. 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. =46rom our proposed charter = (https://datatracker.ietf.org/group/panrg/about): The Internet architecture assumes a division between the end-to-end functionality of the transport layer and the properties of the path = between the endpoints. The path is assumed to be invisible, homogeneous, singular, = with dynamics solely determined by the connectivity of the endpoints and the = Internet control plane. Endpoints have very little information about the paths = over which their traffic is carried, and no control at all beyond the destination = address. Increased diversity in access networks, and ubiquitous mobile = connectivity, have made this architecture's assumptions about paths less tenable. Multipath protocols taking advantage of this mobile connectivity begin to show us = a way forward, though: if endpoints cannot control the path, at least they can determine the properties of the path by choosing among paths available = to them. This research group aims to support research in bringing path awareness = to transport and application layer protocols, and to bring research in this = space to the attention of the Internet engineering and protocol design = community. The scope of work within the RG includes, but is not strictly limited = to: - communication and discovery of information about the properties of a = path on local networks and in internetworks, exploration of trust and risk = models associated with this information, and algorithms for path selection at endpoints based on this information. - algorithms for making transport-layer scheduling decisions based on information about path properties. - algorithms for reconciling path selection at endpoints with widely = deployed routing protocols and network operations best practices. The research group's scope overlaps with existing IETF and IRTF efforts, = and will collaborate with groups chartered to work on multipath transport = protocols (MPTCP, QUIC, TSVWG), congestion control in multiply-connected = environments (ICCRG), and alternate routing architectures (e.g. LISP), and is related = to the questions raised in the multiple recent BoF sessions that have = addressed path awareness and multiply-connected networks (e.g. SPUD, PLUS, = BANANA). The PAN(P)RG intends to meet at each IETF meeting until a determination is made whether or not to charter it. Afterward, the RG = intends to meet at 1-3 IETF meetings per year, and hold one workshop per year, = collocated with a related academic conference.
