摘要:In this paper, a new FPGA-based parallel processor for shortest path searching for OSPF networks is designed and implemented. The processor design is based on parallel searching algorithm that overcomes the long time execution of the conventional Dijkstra algorithm which is used originally in OSPF network protocol. Multiple shortest links can be found simultaneously and the execution iterations of the processing phase are limited to . instead of of Dijkstra algorithm. Depending on the FPGA chip resources, the processor is expandedto be able to process an OSPF area with 128 routers. High speed up factors of our proposal processor against the sequential Dijkstra execution times, within (76.77-103.45), are achieved
