PCE Based Grid Networking

Grid allows creation of abundant services by sharing widely distributed heterogeneous resources. As the Grid technology evolves, the network is elevated as the first-class resource like other Grid resources, i.e. CPU and storages, which can be managed and scheduled altogether. In this paper, we first propose a Grid internetworking architecture based on PCE (Path Computation Element) model. Within this architecture, a virtual service domain framework is presented in a multiple-domain environment. Furthermore, a PCE-based network element and a signaling mechanism are designed to address the inter-domain routing and resource reservation. Within our knowledge, this is the first work ever for Grid internetworking based on IETF PCE protocol.
