Abstract
A conventional technology does not show that the number of middle stage switches is minimized on a non-blocking condition of a multisource and possible multicast Clos type network, and it becomes a high cost system. Further, no addition or deletion of a connection can be done without a data loss. It is an object to provide, as a means for solving the problems, a multisource and multicast possible Clos type network based on such a technology that the number of middle stage switches is minimized on a non-blocking condition and that addition/deletion of a connection to a existing multicast tree can be carried out without a data loss, so that the network can be operated at low cost without a data loss.
