[comp.protocols.tcp-ip] IP Multicasting questions

lazear@GATEWAY.MITRE.ORG (07/18/90)

In looking at IP multicasting (RFC 1112) and its potential use in a
project of ours, a couple of questions came to mind:

	Is there a "reference" implementation?  For SunOS or 4.3BSD?
	How can we obtain a copy?

	Is there any interest or work in progress to extend the registration
	protocol to allow 3rd party joins?  That is, to convey the IP
	address of a system to be added to a multicast address.  We are
	thinking of a coordinating system that would best know which slave
	systems should be in which groups and would register and deregister
	them appropriately.

Thanks in advance for any help.
