Abstract. Multi-cores and multi-processors loosely coupled architectures are interesting commodity off-the-shelf architectures with which to build multicluster configurations as grid environments. However, such grid environments face challenges that must be circumvented. Examples include the heterogeneity of computational resources (e.g. operating systems, processors), of different programming paradigms and of network protocols. Transport protocols are especially important, because they can directly impact the execution of distributed engineering and scientific applications. In this paper, we present an empirical study of the SCTP, XTP and TCP as transport protocols with which to support applications in multi-cluster configurations. The environment includes several networks of workstations (NOWs) interconnected via a wide area network. Our experiments consider throughput and latency parameters against number of flows; the results show performance differences from the three transport protocols over a real distributed production configurations.

New commodity-off-shelf architectures are being adopted as a differential computational power to respond the increase demand to solve a large number of complex applications. These configurations can be considered as special grid environments, called as multi-clusters, where computational resources are scattered over a wide area network. In these grid environments a well known challenge to be circumvented is the heterogeneity of computational resources. Network protocols are especially important, because of the significance for the execution of distributed global applications. As a result, the goal of this paper is to plot performance tendency for TCP, XTP e SCTP protocols referring to throughput, latency and number offlows aspects.
