A group of 2m - 1 routers are interconnected in a centralized binary tree, with router at each tree node. Router I communicate with router J by sending a message to the root of the tree. The root then sends the message back down to J. Then find the mean router-router path length.

m - 1

2 (m - 2)

2 (2m - 1)

(2m - l)/mJ

m - 1

2 (m - 2)
