A new rearrangeable nonblocking photonic multi- log2N network DM(N) is introduced. It is shown that DM(N) network simultaneously possesses many good properties, including those of existing rearrangeable nonblocking multi-log2 N networks and new ones such as O (log N) -time fast parallel self-routing and nonblocking multiple-multicast.
In this paper, we propose a scalable multicast protection scheme based on a dual-homing architecture where each destination host is connected to two edge routers. Under such an architecture, there are two paths from the source of a multicast session to each destination host, which provides a certain level of protection for the data traffic from the source to the destination host. The protection level...
