Session Directory Tool

The Session Directory Tool is a valuable resource for any business looking to engage in multicast session directory management. Designed specifically for the advertisement and joining of multicast conferences on the Mbone, this tool is modeled after the sd tool written by Van Jacobson at LBNL. However, it implements a more advanced version of the session description protocol compared to sd. It was originally created by Mark Handley during his time at UCL under the MICE and MERCI projects, and he now works at ISI.

SDR will continue to be maintained, albeit on a limited basis, as a core part of the infrastructure for conferencing on the CAIRN testbed network as well as the EC MECCANO project. Numerous enhancements and bug fixes have been contributed by experts like Bill Fenner and Van Jacobson, with security features implemented by Edmund Whelan and Goli Montasser-Kohsari at UCL.

This release has seen the addition of a new 'application' media type for session directories, as well as fixes for byte ordering of headers on intel machines, and IP6 address allocation for unix IP6 stacks. The authentication and encryption code now allows for extra space for IPv6 addresses, and the configure scripts feature added IPv6 flags.

Overall, the Session Directory Tool is a valuable and useful tool for businesses looking for efficient multicast session directory management. The constant updates and improvements ensure that this tool stays up to date with the latest technological advancements, making it a reliable resource for businesses of all types.
