Admission control for Grid services in IP networks

Admission control is a key issue for quality of service (QoS) provisioning in IP networks. Two solutions have been proposed successively in this matter: service differentiation (DS) and flow aware networking (FAN). DS operates at the packet level whereas FAN operates at the scale of the IP flow. In this paper, we propose an original approach consisting in applying FAN admission control against DS for grid services. A grid session may be seen as a succession of parallel TCP/IP flows characterized by data transfers with much larger volume than usual TCP/IP flows. We compare by means of computer simulations the efficiency of grid over DS (GoDS) and grid over FAN (GoFAN) architectures.
