ROHC bay-cough at Roke Manor Research, UK

The first interoperability test event for RTP ROHC took place in the week commencing 2001-07-30 at Roke Manor Research, UK. See the report above we gave at the IETF-51.
This is the first packet that was successfully exchanged between independent implementations, with some comments added. Unfortunately, the CRC was wrong (consistently on both sides), so here is a demo program for the four ROHC CRC algorithms to make your life easier.

WG meeting at the 50th IETF, Minneapolis, MN, US

We held a rather tight single-slot WG meeting in Minneapolis. The minutes are here.

Previous Work

The work of the ROHC WG up to spring 2001 focused on the initial main deliverable, the RTP ROHC specification, which supplants the individual contributions that went into it. RTP ROHC has been published as RFC3095, an IETF Standards Track document.
