A Feedback Mechanism for Network Scheduling in LambdaGrids
Next-generation e-Science applications will require the ability to transfer information at high data rates between distributed computing centers and data repositories. A LambdaGrid offers dedicated, optical, circuit-switched, point-topoint connections, which may be reserved exclusively for an application. Though such dedicated high-speed connections eliminate congestion in the network, they effectively push the network congestion out to the end systems, as processing speeds have not kept up with networking speeds. Therefore, developing an efficient transport protocol over such highspeed dedicated circuits is of critical importance. In this work, we propose the idea of a lightweight endsystem protocol, based on performance monitoring, to significantly improve the performance of data transport over a LambdaGrid. In particular, we focus on dynamically monitoring the OS task scheduling at the receiving end-system so that potential end-system congestion may be detected early and appropriat...
