UIBK contributions to EC-GIN

GSWS

The Grid Scene Workflow Simulator was developed by Rene Plattner in his master thesis under the supervision of Michael Welzl for EC-GIN. It enables simulating concrete (mapped) Grid workflows, specified in XML, with a comprehensive network model based on ns-2, for which it communicates back and forth between our own task execution simulator and ns-2 itself.

A library for speeding up Grid service calls with SCTP

This library was developed by Christoph Sereinig in his master thesis under the supervision of Michael Welzl for EC-GIN. It can speed up Java web applications (and consequently Java based Grid applications) by facilitating the usage of SCTP instead of TCP; the speedup is attained by exploiting SCTP's multi-streaming and unordered delivery to avoid TCP's head-of-line blocking delay.

Weighted Congestion Control using MulTFRC (and an equation for multiple TCPs)
