                 draft-gao-flexible-session-protocol-00

Abstract

   FSP is a connection-oriented transport layer protocol that provides
   support for mobility, multi-homing and multi-path by introducing the
   concept of 'upper layer thread ID'.

   It introduces the concept of transmit transaction to facilitate a
   quad-party sub-protocol of shared secret installation.

   It provides transport layer features of zero round-trip connection
   multiplication and on-the-wire compression, in addition to ubiquitous
   message authentication with optional encryption service.
