Abstract: In the development of large electronic equipment, the coexistence phenomenon of many kinds of network is existing due to differences of technical requiremnts, costs and the application scenes. In this heterogeneous network environment, information is a problem that must be faced in the process of efficient, fast and reliable transmission and sharing. Network convergence equipment uses multi network fusion technology to establish bridge mapping between Ethernet nodes and fiber channel (FC) network. With FC ID virtualization, Ethernet nodes are mapped into FC network, forming an integrated network with FC switching network as backbone. This realizes the function of simple routing and real-time exchange between FC protocol and Ethernet protocol.
