<p><P>PROBLEM TO BE SOLVED: To provide technology for minimizing the number of middle stage switches on a non-blocking condition of a multisource and possible multicast Clos type network. <P>SOLUTION: A multisource and multicast possible Clos type network is provided 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 an 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. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
