... 2. What is the channel bisection width for the star network [2] A cut of a network C(N1,N2) is a set of channels that partition the set of all nodes into two disjoint sets N1 and N2. Each element of C(N1,N2) is a channel with a source in N1 and destination in N2 or vice versa. A bisection of a netw ...
