Fairness Issues When Transferring Large Volumes of Data on High Speed Networks With Router-Assisted Transport Protocols

This paper presents improvements of the explicit Control Protocol (XCP) in order to support fairness between XCP and TCP flows. Our mechanism is based on two main components: estimations of the resources needed by XCP, and limitation of the resources taken by TCP. The set of simulations shown in this paper proves that we can guarantee a fairness level between XCP and TCP. We think that our TCP-XCP fairness mechanism can be perfectly applied for Long Distance Data Grids, where senders need to transfer large volumes of data.
