A light-weight SIP-based execution management service for bag-of-tasks grid system

The paper presents application of SIP protocol in the context of bag-of-tasks grid architecture. The SIP protocol has been used in realization of the execution management service. The main idea is use of stateful SIP proxy as request broker. The paper provides description of the concept, and the prototype system that has been built, as well as calculation of estimated performance level and it's relation to maximum RTT of grid system. The main advantage of this light-weight grid architecture is the reuse of a mature infrastructure.
