Blocking of dynamic multicast connections in a single link.
TD(97)46 COST257, (Sep. 1997)

Abstract

In this paper, a method for calculating blocking experienced by dynamic multicast connections in a single link is presented. An originating office provides a number of channels distributed to the users by multicast subtrees which evolve dynamically as users join and leave the channels. We reduce this problem to a generalized Engset system with unidentical users and generally distributed holding times, and derive the call and channel blocking probabilities as well as the link occupancy distribution.
