Traffic is uniform. You are to consider various designs and find the maximum throughput. Which network provides the maximum capacity per user. Only four wavelengths are possible on the optical medium. A node may have no more than four transmitters and receivers and all may operate in parallel.
Traffic is uniform.
For the 8 node re-circulating perfect shuffle lightwave network. Consider heavy traffic from node 1 to nodes 4 and 2 and from node 8 to node 2. Repeat the above if node 6 fails after node 8 fails. Now, suggest re-arranging the network to reduce the number of hops.
