Fat tree: It is a customized version of tree network. In this network bandwidth of edge (or connecting wire between nodes) increases in the direction of root. It's a more realistic imitation of normal tree where branches get thicker in the direction of root. It's more popular in comparison to structure since practically the more traffic takes place towards the root as compared to leaves therefore if bandwidth does not change the root would be a bottleneck causing more delay. In a tree this problem is avoided due to higher bandwidth.

Hardware difficulty of Benz Network: - Benz network uses smaller switches and it gives excellent connectivity. To find hardware difficulty of Benz network let us presume that
Time out Timers are used to protect against lost packet. Each packet must have its own logical timers since only a single packet will be retransmitted after timeou
