Abstract
The invention discloses an address synchronization method and device in a VSU, a VSU system, a host device and member devices. The address synchronization method and device, the VSU system, the host device and the member devices are used for solving the problem that in the prior VSU art, due to data flow migration across the member devices, communication of the VSU is abnormal. The address synchronization method comprises the following steps that after a member device of the VSU detects an MAC address of newly-added data flow, an address updating message is sent to a host of the VSU, the host of the VSU conducts synchronous address updating according to the address updating message and sends address deletion message to other member devices except that member device sending the address updating message, the address deletion message comprises the MAC address of the data flow of the address updating message, after the member devices of the VSU receive the address deletion message, the MAC address of the data flow is deleted, and therefore the MAC address of the same data flow is only stored in one member device in the same moment.
Description
Technical field
The present invention relates to network communicating system, particularly, relate to address synchronization method and device, VSU system, main process equipment and member device in a kind of virtual switch unit (VSU, Virtual Switch Unit).
Background technology
VSU is a kind of network system Intel Virtualization Technology, supports many switch devices are combined into to single virtual switch machine equipment by stacking link (VSL), and the member device that is about to several physics is equivalent to a virtual logical device, as shown in Figure 1.In Ethernet switch, by address aging mechanism, the MAC Address be connected or communicate is managed, particularly, Ethernet switch starts the aging timing of this address when learning a new address, before reaching aging timing, take if Ethernet switch is not received again the message that this address is source MAC, this address can be deleted after reaching ageing time from mac address table.In VSU, in the situation that the MAC managed in the member device of VSU occurs to increase newly, deletes or change, trigger the synchronous learning functionality of MAC Address of the main frame of VSU.
In the VSU practical application, often due to the of short duration variation of external network topology (such as change topology or exchange device more) or route selection etc., cause striding equipment migration in pile system in the data flow short time, and this migration will cause the pile system network can't carry out normal data communication.Need the user manually member device to be carried out to the address deletion action.In conjunction with the scene graph of data flow striding equipment migration in the VSU shown in Fig. 2, the concrete steps of the message repeating under the scene of data flow striding equipment migration of the member device in VSU are as follows:
Step 1, in the pile system formed by member device A and member device B, in pile system, the data flow of second line of a couplet equipment C is transmitted toward first line of a couplet equipment D by the port of member device A, member device A learns this data flow MAC Address, the port that corresponding ports is member device A; The main frame of VSU will synchronously be learnt this MAC Address simultaneously;
Step 2, because outside topological environmental of short time changes, the data flow of second line of a couplet equipment C moves to equipment B by device A, thereby equipment B is learnt the MAC Address of this data flow, the main frame of VSU will synchronously be learnt this MAC Address, the MAC Address corresponding ports of this data flow will be updated to the port of equipment B;
Before in device A, the address of this data flow arrives ageing time, because reaching ageing time, the address of this data flow in device A do not have to change, what therefore in VSU, preserve is the port of data flow corresponding device B, now device A and equipment B will be preserved the MAC Address of this same data flow simultaneously, and correspond to the port of distinct device; Like this, during the message of other these MAC Address of port access, will be forwarded to due to the address corresponding relation retained in device A the port of device A, thereby cause the access user MAC Address telex network therewith of other ports on device A on device A;
After step 3, outside topological environmental recover to stablize, before in device A, the MAC Address of this data flow arrives ageing time, data flow is moved back device A, and the mac address information in device A is change not, and the main frame that can not trigger VSU carries out MAC Address and synchronously learns; Before the address of this data flow of equipment B does not reach ageing time, the port of the MAC Address corresponding device B that remains this data flow preserved in the main frame of VSU; During the message of other these MAC Address of port access, will be forwarded to due to the address corresponding relation retained in equipment B the port of equipment B, thereby cause the access user MAC Address telex network therewith of other ports on equipment B on equipment B.
Step 4, after a period of time, because data flow is transmitted constantly on device A, the address aging on equipment B, the main frame that has simultaneously triggered VSU also will correspondingly fall the address aging of this data flow, synchronously the mac address information of this data flow be deleted.Like this, in the main frame of VSU, finally do not preserve the mac address information of this data flow, cause the VSU data communication abnormal.
Visible, in existing VSU technology, exist data flow to cause the problem of the communication abnormality of VSU across the member device migration.
