Embodiment Construction

[0029] The present invention proposes a method for optimizing the FSPF protocol applied to FCoE networking. The method is applied to an FCoE networking system including multiple switches. When one of the multiple switches is used as a local switch, other switches is the peer switch of the local switch, such as figure 2 A flow chart of the method for optimizing the FSPF protocol applied to FCoE networking for the present invention, the method comprising:

[0030] Step 201: the local switch receives the HLO SW_ILS message from the peer switch;

[0031] Step 202: According to the Domian ID of the peer switch carried in the HLO SW_ILS message, the local switch searches for whether it has created the neighbor state machine corresponding to the peer switch; if it has not yet created, then execute step 203;

[0032] Step 203: The local switch creates a neighbor state machine corresponding to the peer switch, and completes a neighbor discovery process for the peer switch.

Abstract

The invention provides a method applied to FCoE (Fiber Channel over Ethernet) networking and used for optimizing an FSPE (Fiber Shortest Path First) protocol and switchboards. The method is applied to an FCoE networking system comprising a plurality of switchboards; when one of the switchboards is a local-end switchboard, the other switchboards are opposite-end switchboards of the local-end switchboard; and the method comprises the following steps of: receiving HLO SW_ILS (Hello Switch Internal Link Services) messages from the opposite-end switchboards by the local-end switchboard, and searching whether neighbor state machines corresponding to the opposite-end switchboards are established in the local-end switchboard according to domain identifiers (ID) of the opposite-end switchboards carried in the HLO SW_ILS messages; and if the neighbor state machines are not established, establishing the neighbor state machines corresponding to the opposite-end switchboards to finish a neighbor discovery process of the opposite-end switchboards. By adopting the method and the switchboards, the neighbor switchboards of the switchboards in an FCoE network can be discovered by the switchboards in the FCoE network.

Description

technical field [0001] The invention relates to the technical field of Fiber Channel over Ethernet (FCoE, Fiber Channel over Ethernet), in particular to a method and a switch for optimizing the Fiber Shortest Path First (FSPF, FabricShortest Path First) protocol applied to FCoE networking. Background technique [0002] In an FC network, each switch is identified by a domain identifier (Domain ID), and packets are forwarded between different switches. The FSPF protocol is a dynamic route discovery protocol used by FC networks. This protocol is described in the fs-sw-5 specification released by the T11 organization. The FSPF protocol connects all the switches in the FC network, and calculates the route from one switch to other switches in the FC network by synchronizing the link state database (LSDB, Link StateDataBase), so as to transparently realize the connection between one N node and another N node. Node access. [0003] The above LSDB is a collection of Link State Reco...
