Fig. 4 provide for the embodiment of the invention another be the method flow diagram of network dividing domain.Present embodiment can realize that based on above-described embodiment as shown in Figure 4, the method for present embodiment comprises:

Registration message is published in step 401, reception, and the described registration message of publishing comprises the described device type information of publishing the second equipment of registration message of transmission.

Be the process of network dividing domain when in the above-described embodiments, having described server or memory device login FC network.It is the process of network dividing domain that the present embodiment emphasis is described when having memory device or server to publish the FC network.

The executive agent of present embodiment method also is the switch in the FC network.

Concrete, when the second equipment in the FC network need to be published the FC network, publish registration message to switch transmission direct-connected with it.Direct-connected switch is published registration message with this and is added in the name server, and name server is synchronized to other switches in the FC network.Based on this, the executive agent of present embodiment is if direct-connected switch, and second equipment that then can receive directly sends publishes registration message; If the executive agent of present embodiment is indirectly connected switch, then can receive the registration message of publishing by direct-connected switch forwarding.

Step 402, according to the described device type information of publishing in the registration message, determine that the second equipment is server or memory device; If second equipment of determining is server, then execution in step 403; If second equipment of determining is memory device, execution in step 406.

Step 403, determine whether there is memory device in the second equipment place server domain; If determine that the result is yes, execution in step 404; If determine that the result is no, execution in step 405.

Step 404, when in the second equipment place server domain, having memory device, the RSCN message that the second equipment is published generation sends to the memory device in the second equipment place server domain, memory device in the second equipment place server domain is moved in the memory device territory from the second equipment place server domain, and delete the second equipment place server domain, delete memory device in the second equipment, the second equipment place server domain and the mapping relations between the second equipment place server domain three, finish this time operation.

Step 405, when in the second equipment place server domain, not having memory device, delete the second equipment place server domain, delete the second equipment and the second equipment place server domain mapping relations between the two, finish this time operation.

Switch receive publish registration message after, determine that according to device type information wherein the second equipment is server or memory device.

If second equipment of determining is server, then the second equipment is understood corresponding server domain, so switch determines whether there is memory device in the second equipment place server domain, namely determine whether to exist the memory device that connects with the second equipment.Concrete, switch can be judged according to each mapping relations corresponding to the second equipment that record before.

Have memory device if determine in the second equipment place server domain, then switch will send to because of the RSCN message of publishing generation of the second equipment each memory device in the second equipment place server domain, to announce the variation of the second equipment.Simultaneously, switch is moved to each memory device in the second equipment place server domain in the memory device territory from this server domain, waits for that other servers or the second equipment continue to use after again logining the FC network.If the second equipment is published the FC network, the server domain that then the second equipment is corresponding has not just existed yet, the old friend changes planes also to be needed the second equipment place server domain deletion, the second equipment, the memory device in the second equipment place server domain and the mapping relations between the second equipment place server domain three of simultaneously deletion record.For example, if the mapping relations here are to be made of the list item shown in similar table 1 or the table 2, then switch is with the respective table entry deletion.

If determine in the second equipment place server domain and do not have memory device, there are not the second equipment, and the memory device that connects of the second equipment and the mapping relations between the second equipment place server domain three this moment, so switch is directly with the deletion of the second equipment place server domain, and the second equipment deleted with the second equipment place server domain mapping relations between the two gets final product.For example, if the mapping relations here are to be made of list item shown in table 1 or the table 2, then switch is with this list item deletion.

Step 406, determine that described the second equipment is whether in the memory device territory; If determine that the result is yes, execution in step 407; If determine that the result is no, execution in step 408.

Step 407, when the second equipment is in the memory device territory, delete the second equipment and memory device territory mapping relations between the two, finish this time operation.

Step 408, when the second equipment is not in the memory device territory, the RSCN message that the second equipment is published generation sends to server in the second equipment place server domain and other memory devices except the second equipment, delete server in the second equipment, the second equipment place server domain and the mapping relations between the second equipment place server domain three, finish this time operation.

If second equipment of determining is memory device, because this memory device may be in the memory device territory, also might be in certain server domain, the old friend changes planes and determines that further the second equipment is whether in the memory device territory.Concrete, switch can be judged according to the mapping relations with the second device-dependent that record before.

If second equipment of determining is in the memory device territory, second equipment that then illustrates is not used by any server, does not need to carry out the announcement of RSCN message, so only need the second equipment and the mapping relations deletion between the two of memory device territory of record are got final product.For example, if the mapping relations here are a list item, then switch gets final product this list item deletion.

If second equipment of determining is not in the memory device territory, illustrate that then the serviced device of the second equipment uses, in the server domain at the server place of using the second equipment, based on this, switch will send to because of the RSCN message of publishing generation of the second equipment server in the second equipment place server domain and other memory devices except the second equipment, announcing the variation of the second equipment, and delete server and the deletion of the mapping relations between the second equipment place server domain three in the second equipment, the second equipment place server domain.For example, if the mapping relations here are to be made of the list item shown in similar table 1 or the table 2, then switch can get final product the respective table entry deletion.

By as seen above-mentioned, in the present embodiment, by dividing different territories for the FC network, memory device and the server of needs communication are put in the same territory, like this when memory device or server are published the FC network, the RSCN message that produces only needs to announce in same territory, has reduced the network resources waste that unnecessary announcement process causes, and is conducive to improve stability and the availability of network.In addition and since the present embodiment method provide be the method for network dividing domain, do not need keeper's participation, automatically finished by the switch in the FC network, have realize flexible, the more high advantage of efficient.
