A new Request for Comments is now available in online RFC libraries. RFC 5058 Title: Explicit Multicast (Xcast) Concepts and Options Author: R. Boivie, N. Feldman, Y. Imai, W. Livens, D. Ooms Status: Experimental Date: November 2007 Mailbox: rhboivie at us.ibm.com, nkfeldman at yahoo.com, ug at xcast.jp, wim at livens.net, dirk at onesparrow.com Pages: 35 Characters: 80072 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ooms-xcast-basic-spec-13.txt URL: http://www.rfc-editor.org/rfc/rfc5058.txt While traditional IP multicast schemes (RFC 1112) are scalable for very large multicast groups, they have scalability issues with a very large number of distinct multicast groups. This document describes Xcast (Explicit Multi-unicast), a new multicast scheme with complementary scaling properties: Xcast supports a very large number of small multicast sessions. Xcast achieves this by explicitly encoding the list of destinations in the data packets, instead of using a multicast group address. This document discusses Xcast concepts and options in several areas; it does not provide a complete technical specification. This memo defines an Experimental Protocol for the Internet community.
