Topological design comparison for multicast network
Takumi Miyoshi, Yoshiaki Tanaka, Kaoru Sezaki · 2003
Since the multicast connection form is clearly different from the point-to-point one, the optimal network topology will also be different if many multicast services are provided. The delta-star topology has been proposed as an effective topology for a point-to-point network when reliability is a consideration. It may also be effective for multicast networks, since it is a combined form of the ring topology, suitable for multicast connections, and the star topology, suitable for point-to-point connections. The network construction cost is examined by applying each of the following topologies: star, ring, multi-ring, and delta-star. The results show that the Delta-Star topology is the most suitable for multicast networks in many cases.
