Comments on "Wide-sense nonblocking multicast Log/sub 2/(N,m,p) Networks"

Recently, Hwang and Lin derived nonblocking conditions for multicast connections in Log/sub 2/(N,m,p) networks. They improved some conditions obtained earlier by Kabacin/spl acute/ski and Danilewicz. In this letter, we identify some inaccuracy in present results concerning wide-sense nonblocking Log/sub 2/(N,m,p) multicast networks, and give the correct results.
