Congestion aware multipath transport protocols in wired and wireless networks.
P. Key (Microsoft Research)
We describe multipath routing problems in wired and wireless communication networks, using flow-level models. We use welfare maximisation both as a framework for discussing resource allocation problems and also as a goal to aim for. We show that welfare maximization requires active balancing data across the active paths, taking current network conditions (such as congestion) into account. Implementing such ideas in existing networks may require new transport protocols to be designed and deployed. Multipath routing in wireless is more complex than for wired networks. We discuss approaches which also address scheduling issues.
