Initial Post Sockets draft submitted to IETF

We've submitted an initial draft on Post Sockets, An Abstract Programming Interface for the Transport Layer to the IETF. This draft proposes an outline new API for the transport layer that could form an eventual replacement for the Berkeley Sockets API. It aims to support the features of modern transport- and path-layer protocols, including long-lived security associations and multipath operation.

This work builds on the initial Post Sockets API that Brian Trammell presented in the TAPS working group at IETF 96, and on our work on Requirements for Real-time Transport Services presented at the same meeting.
