Abstract
The point­to­multipoint ABR service within ATM is
important for many emerging data applications. The ob­
jective is for the source to operate at a rate representing
its max­min fair share over the bottleneck link in the mul­
ticast tree over which the connection is established. Re­
source Management (RM) cells are used by receivers to
convey back to the source an explicit rate indicating their
bandwidth fair share on the bottleneck of the path leading
to them. Switches in the multicast tree consolidate the in­
formation in backward RM cells received from downstream
switches or receivers and forward this consolidated infor­
