Routing generation for implementation of fiber channel over ethernet

摘要

According to an example, a routing generation method and apparatus is applied in Fiber Channel over Ethernet (FCoE). Based on the additions to the TLV, which may be carried in the Hello packet and the LSP packet, the Hello packet of the ISIS protocol may be used to implement neighbor discovery of the FC protocol, and the LSP synchronization of the ISIS protocol may be used to implement the link information synchronization of the FC protocol. Thus, the FC routing may be generated without the FSPF. Therefore, FCoE may be implemented with a lower cost.

1. A routing generation method for implementation of Fiber Channel over Ethernet (FCoE), applied in a network that includes a plurality of network equipment, each of the plurality of network equipment supporting fiber channel (FC) protocol, the method comprising:
sending, from a local network equipment to a neighbor network equipment, a neighbor negotiation packet that includes an FC protocol identification, a Domain_ID and an originating port index of the local network equipment, wherein the FC protocol identification includes a value to express a Network Layer Protocol ID (NLPID) of the FC protocol; receiving, from the neighbor network equipment, a neighbor negotiation packet that includes the FC protocol identification, a Domain_ID and an originating port index of the neighbor network equipment; generating, by the local network equipment, a link state information packet that includes the FC protocol identification, a FC link identification, and a neighbor port index of the local network equipment; synchronizing link state information of the local network equipment with the neighbor network equipment; and if the neighbor port index of the link state information packet of the local network equipment is the same as the originating port index of the neighbor network equipment, and a neighbor port index of the link state information packet of the neighbor network equipment is the same as the originating port index of the local network equipment, calculating and generating a FC routing from the local network equipment to the neighbor network equipment.
