Abstract
In Internet multicast, the set of receivers can be dynamic with receivers joining and leaving
a group asynchronously and without the knowledge of the source(s). The Internet today uses
source­based scoping by which the source determines how far its multicast transmissions will
propagate. This mechanism, however, does not allow a receiver to bound the number of hops
added to a multicast routing tree as a result of its join request or its continued membership.
In this paper we explore the use of receiver­based scoping, in which a receiver's join request is
augmented with one or more scope values. By use of these values, the receiver specifies its wish to
