Description
Technical Field
The present invention relates to a network communication system, and in particular, to an address synchronization method and apparatus in a Virtual Switch Unit (VSU), a VSU system, a host device, and a member device.
Background
The VSU is a network system virtualization technology, and supports the combination of multiple switch devices into a single virtual switch device through a stack link (VSL), that is, several physical member devices are equivalent to a virtual logical device, as shown in fig. 1. In the Ethernet switch, the MAC address connected or communicated is managed through an address aging mechanism, specifically, the Ethernet switch starts aging timing of the address while learning a new address, and before the aging timing is reached, if the Ethernet switch does not receive a message taking the address as a source MAC address again, the address is deleted from a MAC address table after the aging time is reached. In the VSU, when MAC managed in the member device of the VSU is added, deleted or changed, the MAC address synchronization learning function of the host of the VSU is triggered.
In practical applications of VSUs, often, due to a short change in external network topology (for example, changing topology or replacing devices) or routing, data flows are migrated across devices in the stacking system in a short time, and such migration will cause the stacking system network to fail to perform normal data communication. The user is required to manually perform an address deletion operation on the member device. With reference to the scenario diagram of data flow migration across devices in the VSU shown in fig. 2, the specific steps of packet forwarding of the member devices in the VSU in the scenario of data flow migration across devices are as follows:
step 1, in a stacking system formed by a member device A and a member device B, a data stream of a lower device C in the stacking system is transmitted to an upper device D through a port of the member device A, the member device A learns an MAC address of the data stream, and a corresponding port is the port of the member device A; meanwhile, the VSU host learns the MAC address synchronously;
step 2, as the external topological environment changes in a short time, the data stream of the equipment C connected in series is transferred from the equipment A to the equipment B, so that the equipment B learns the MAC address of the data stream, the host of the VSU synchronously learns the MAC address, and the port corresponding to the MAC address of the data stream is updated to be the port of the equipment B;
before the address of the data stream in the device a reaches the aging time, because the address of the data stream in the device a does not reach the aging time and does not change, the address stored in the VSU is the port of the device B corresponding to the data stream, and at this time, the device a and the device B simultaneously store the MAC address of the same data stream and correspond to the ports of different devices; thus, when other ports on the device A access the message of the MAC address, the message is forwarded to the port of the device A due to the address corresponding relation reserved in the device A, so that access users of other ports on the device A cannot communicate with the MAC address user;
step 3, after the external topological environment is recovered to be stable, before the MAC address of the data stream in the equipment A reaches the aging time, the data stream is migrated back to the equipment A, the MAC address information in the equipment A is not changed, and a VSU host is not triggered to carry out MAC address synchronous learning; before the address of the data stream of the device B does not reach the aging time, the port of the device B corresponding to the MAC address of the data stream is still stored in the host of the VSU; when other ports on the device B access the message of the MAC address, the message is forwarded to the port of the device B due to the address correspondence relationship reserved in the device B, so that the access users of other ports on the device B cannot communicate with the MAC address user.
And 4, after a period of time, as the data stream is continuously transmitted on the device A, the address on the device B is aged, and meanwhile, the host triggering the VSU also correspondingly ages the address of the data stream, namely, the MAC address information of the data stream is synchronously deleted. In this way, the host of the VSU does not ultimately store the MAC address information of the data flow, resulting in an abnormal VSU data communication.
It can be seen that in the existing VSU technology, there is a problem that data stream migration across member devices causes communication anomaly of the VSU.
