Data intensive applications require massive amount of data to be transported over shared wide area networks. Traditional network congestion control and routing schemes have proven inadequate for fully utilizing available network resource for high-bandwidth data transport. In this work, we explore the flexibility of control at the application layer and propose various application level data relay schemes to largely improve the data throughput by optimally integrating application level routing and transport layer control. The proposed algorithms can be easily implemented in overlay networks. Preliminary experiments have shown that our relay schemes are e#cient in utilizing network resource for high-bandwidth data transport. The impact of application level relays on the underlay network is also discussed.
