Heterogeneous Network Bridging Of Multi-protocol Based On FC-GE And Related Software Design

Nowadays,the internal communication network of large-scale embedded system is more and more complex. It often contains FC communication nodes, Ethernet communication nodes and Rapid IO communication nodes, constituting a heterogeneous network of multi-protocols. Setting the advantages of channel and network in one, Fibre Channel is very suitable for backbone network, so as to realize the converged communication of different sub-networks. The scheme proposed in this article of heterogeneous network bridging is an important application in the field of converged communication of complex embedded system.This article makes a deep analysis of FC protocol, TCP/IP protocol, Rapid 10 protocol, and Rocket IO technology, and points out the differences between them. For the coexistence of various low level protocols of communication nodes after carefully studying IPoFC and FCoE network convergence technology, this article comes up with a scheme of network bridging which is based on network virtualization, and realizes the software design of FC-IP, FC-Rapid IO, FC-Rocket IO bridging. The software design mainly includes:Ethernet transceiver module, FC transceiver module, bridging table mansgement module, network security mansgement module, FC link-state monitoring module, and Rapid IO registration and unregistration module.After rigorous testing, it verifies that the bridging scheme achieves the goal of a good interconnection of different network protocols.The actual data bandwidth meets the communication demands. At the same time, it supports network security management and link-condition detecting and monitoring.All in all, this article makes some exploratory research on network convergence for complex embedded system.
