A number of people in the Internet community have been advocating that the IETF consider standardizing a method for handling multicast to small groups, where "small" is generally understood to be in the range of 3-10 or so participants. The rationale for this is twofold: 1) there are alleged to be a number of very important applications which have a small numbers of participants per group (e.g. classic audio and video conferencing, collaboration tools, etc.) with an extremely large number of such groups simultaneously active on the Internet. 2) Existing IP multicast methods, including newer specialized schemes like Source Specific Multicast (SSM) are generally thought to have scaling problems when there are a very large nubmer of groups, because of per-group state in all the intermediate routers. Because of the range of possible approaches to this problem and the potential widespread impact on portions of the IP protocol suite, router implementation, operational practices, etc. of the Internet, the BoF is being jointly hosted by the Routing and Internet areas, and will be chaired by Randy Bush of the OPS area.
