Session Layer Burst Switching for High-Performance Data Movement

Time 07/12/11 02:40PM-03:00PM

Session Abstract

We present Session Layer Burst Switching (SLaBS) as an architecture for improving efficiency and utilization of dynamically provisioned network resources. Instead of reserving a dedicated
``circuit' per application, SLaBS forms data bursts, at transport-layer gateways in the network, which are able to intelligently schedule and switch these bursts along allocated network
paths as they become available. Using session-layer protocol data units, called ``slabs', significant amounts of data can be buffered. This allows the burst size to be adapted to the characteristics of the network path and optimally transferred via explicit buffers negotiated
between gateways. A proof-of-concept prototype of SLaBS has been implemented within the Phoebus Gateway and we present the outcome of our early testing with performance results.
