How can I get it ? Jacob Rekhter (YAKOV @ IBM.COM) The IP Multicasting extensions described in RFC988 have been implemented for 4.3bsd Unix by Karen Lam of BBN Labs. This software is available for experimental purposes to sites that have 4.3bsd source code. In addition to full support for the RFC988 extensions, the software includes a prototype "multicast agent" demon which enables a Unix host to act as an inter-network relay for IP multicast packets, and a version of Berkeley's "rwhod" that uses multicast instead of broadcast datagrams. To obtain the software, a site will have to sign a licence with BBN certifying that they possess a 4.3bsd source license. The software is distributed on a 1600bpi tar tape and comes with printed installation and usage notes. Interested parties should contact Craig Partridge (craig@bbn.com or craig@nnsc.nsf.net). It is important to note that the internetwork multicasting protocols are still under development and subject to change. Sites that obtain the software are urged to contact Steve Deering at Stanford University (deering@pescadero.stanford.edu) who maintains a mailing list for bug reports, updates, and discussion of changes to the multicast software and protocols.
