IMXP
charter-ietf-imxpbof-01

This BOF will discuss IMXP, an application-layer routing
infrastructure,
and how it may be used to support messaging and presence for
applications requiring different levels of service.

A number of messaging systems operate over the Internet (and provide
useful service in doing so); however, each of these services relies on
a
set of quality of service assumptions that limit its usefulness to
other
applications. For example, the SMTP-based infrastructure provides
extraordinary reach, but is inappropriate for either instant messaging
(which requires very low latency between posting and delivery) and
hardened messaging (which requires audit trails, reliability
guarantees,
et&c). Similarly, although presence information was readily accessible
on Internet-connected systems years ago -- when a user had an open
session to a well-known multi-user system, friends and colleagues could
easily tell -- there is no standard way to make this information known
to peers.
