The general case of multiplane wide-sense nonblocking multicast switching networks which are based on the baseline network are considered in this paper. Up to now, widesense nonblocking (WSNB) log2 (N, 0, p), log2 (N,m, p) and logd (N, 0, p) switching networks have been considered for multicast connections. A control algorithm under which these networks are WSNB is called the variable-size blocking window algorithm. In this paper, the path-searching algorithm is adopted for logd (N, m, p) networks with m extra stages and for general case d ≥ 2. The WSNB multicast conditions for logd (N, m, p) networks are presented (without proofs) and the optimal multicast switching networks are investigated.
