摘 要:In this dissertation, we suggest that a significant aspect of the difficulty in studying limits of communication over networks lies in the unidirectional aspect of the problem. Under different assumptions that rid the problem of this particular aspect by introducing a suitable symmetry, either in the underlying network or in the traffic model, we find that simple schemes are approximately optimal in achieving these fundamental limits. We demonstrate this as a meta-theorem in the class of wireline networks and Gaussian networks. The key contribution driving these results is a new outer bound that we call the Generalized Network Sharing bound.
