The Multimessage Unicast Capacity Region for Bidirectional Ring Networks
Serap A. Savari, Gerhard G. Kramer · 2006
The capacity region for multiple unicast sessions on a bidirectional ring network is established and is shown to be achieved by routing. The proof uses recently developed progressive d-separating edge set bounds, new extensions of these bounds, as well as tools from the literature on the multicommodity flow problem
