Embodiment Construction
[0018] The main idea of the present invention is: after the master switch is elected, the master switch uniformly sends DIA requests to other non-master switches in the fabric network where it is located, and performs domain ID distribution. After the assignment is completed, the master switch sends an EFP notification message to all non-master switches at one time.
[0019] The present invention is realized in a Fabric network formed by interconnecting FCF switches supporting the FCOE protocol.
[0020] The flow chart of the inventive method is as image 3 As shown, there are five steps:
[0021] In the first step, the master switch assigns the minimum available domain ID to itself, updates the local domain ID list, and sends an updated EFP notification message;
[0022] In the second step, the master switch sends a DIA message to the adjacent non-master switch, and after the adjacent non-master switch receives the DIA, it also sends the DIA message to its adjacent non-ma...

The invention discloses a method for realizing ID (identification) distribution of an FCOE (fiber channel over Ethernet) Fabric network domain. The method comprises the following steps that 1) a main switchboard is used for distributing a domain ID to self, updating a local domain ID list, and sending an EFP (electronic field production) announcement to a neighboring switchboard, and the neighboring switchboard is used for forwarding the EFP announcement; 2) the main switchboard is used for sending a DIA (diagram) message to the neighboring switchboard, and the neighboring switchboard is used for forwarding the DIA message; 3) after the DIA message is received by each non-main switchboard, DIA-ACC is replied and a RDI (real-time data interface) message is sent to the main switchboard to request a domain ID; 4) after the main switchboard finishes distribution of the domain ID to each non-main switchboard, the local domain ID list is updated, and an updated EFP announcement is sent; 5) according to the received EFP announcement, each non-main switchboard is used for updating the local domain ID list. According to the method, the main switchboard is used for distributing the domain ID and the announcement to the non-main switchboard in a network in a unified manner, so that the network resource can be saved, and the operating efficiency of the network is improved.
Description
technical field [0001] The invention relates to a domain ID (Identifier Domain) distribution technology in a network, in particular to a method for obtaining a domain ID by a switch in an FCOE Fabric network running an optical fiber protocol on the Ethernet. Background technique [0002] Data centers are growing at an unprecedented rate. In order to reduce the construction costs brought by multiple parallel network architectures, multi-network integration has become an inevitable trend. FCOE (Fibre Channel over Ethernet) is a network convergence technology that enables storage networks and Ethernet to share a single, integrated network infrastructure. In Ethernet, FCOE Forworder (FCF) switches with FCOE functions form a fabric network, that is, FCOE Fabric. [0003] The FCOE Fabric network initialization process is as follows: figure 1 shown. Step 1 is FIP (Fabric initialization Protocol) initialization. After the switches in the network are powered on and started, FCF sw...
