Abstract
Quality-of-Service (QoS) is a key issue for grid services provisioning. QoS architectures originally developed for the Internet such as DiffServ (DS) have been tested in grid environment. We present in this chapter the investigation on the potentialities of a new innovative Internet QoS architecture known as Flow-Aware Networking (FAN). FAN is a flow-based networking architecture and it appears as the most promising alternative to DS for QoS provisioning in IP networks. DS proceeds to traffic differentiation and QoS provisioning through IP packet marking whereas FAN consists in implicit IP flow differentiation and a flow-based admission control. A grid traffic session may be seen as a succession of parallel TCP flows with voluminous data transfers (e.g. GridFTP). In this chapter, we compare by means of computer simulations the performance of FAN and DS architectures under the mix traffic composed by Internet and grid services.
