Strictly Nonblocking Three-Stage Clos Networks With Some Rearrangeable Multicast Capability.

Hwang and Lin introduced a new nonbiocking requirement for 2-cast traffic which imposes different requirements on different types of coexisting calls. The requirement is strictly nonblocking for point-to-point calls among the 2-cast traffic, and is rearrangeable for genuine 2-cast calls. We generalize the 2-cast calls to multicast calls and give a sufficient condition for such networks when the number of multicast calls is upper bounded. [ABSTRACT FROM AUTHOR]
