The aging method of the MAC address comprises the following steps of: sequentially acquiring MAC address table entries from a local MAC address table by an overall system; judging the aging states of the MAC address table entries in all subsystems; notifying all the subsystems to age the MAC address table entries under the condition that the MAC address table entries in all the subsystems are all in aging states; and if not, keeping the MAC address table entries in all the subsystems alive. The invention can be used for enhancing the property and the processing capacity of the system.
Description
Technical field
The present invention relates to the communications field, relate in particular to the aging method and the system of a kind of medium access control (Media Access Control abbreviates MAC as) address.
Background technology
MAC Address is the sign of identification local area network (LAN) (Local Area Network abbreviates LAN as) node, and the interface of itself and equipment (for example, network interface card) is globally unique.Usually, MAC Address is 48, represent with 12 hexadecimal numbers, wherein, preceding 6 numbers are managed by Institute of Electrical and Electronics Engineers (Institute for Electrical and Electronic Engineers abbreviates IEEE as), be used to discern the producer or manufacturer, constitute and organize unique identifier (Organizational Unique Identifier abbreviates OUI as), back 6 numbers generally comprise the set point of network interface card sequence number or specific hardware manufacturer.
Introduce several notions relevant below with MAC Address:
(1) MAC address learning: the source MAC of the message that each received is stored in this study VLAN (Virtual LAN Local Area Network, abbreviate VLAN as) lining, so that the follow-up message of sending to this address only is forwarded to this place, address interface, rather than be forwarded to the total interface of VLAN.As seen, MAC address learning is to transmit the port of past appointment afterwards in order to allow message arrive equipment, and then reduces the traffic carrying capacity in the local area network (LAN), helps the traffic carrying capacity of coupled local area network (LAN) is minimized.
(2) MAC address aging: through after a while (for example, Yu Ding ageing time) afterwards, MAC Address is deleted.Because each MAC Address all is to take actual software and hardware resources,, just must delete and discharge software and hardware resources when certain MAC Address is not deposited when being necessary.
(3) MAC Address keep-alive: if in predetermined periods (for example, ageing time), receive this MAC Address again; this MAC Address just should be by study (existing) so; should be by not aging yet, can reset predetermined periods this moment, restarts timing.
Fig. 1 is according to the schematic diagram that concerns between each subsystem in the distributed system of correlation technique and each management system, as shown in Figure 1, for distributed network equipment at a subsystem (subsystem 1, port one 2) learns after the MAC Address on, need be synchronized to other all subsystems to this MAC Address by the subsystem synchronization module gets on, could guarantee that like this other subsystems receive after the message of this MAC Address, can be forwarded on this MAC Address corresponding port of learning and remove (on subsystem 1 port one 2).
If this MAC Address on subsystem 1 port one 2 has stream to exist always; then all need to keep on all subsystems can not be deleted for this MAC Address; owing to only receive on subsystem 1 port one 2 that the data flow of source MAC could keep-alive on subsystem 1; so, can't receive that other subsystems of such flow have the process of " false aging ".For example, software is after receiving this " false aging " message, because the hardware mac address list item still exists this moment, thus at first can judge port in the mac address table whether on this subsystem, if not, then ignore this message.So; MAC Address on other subsystems is can be not deleted; the principle that Here it is only has the ownership place subsystem just can initiate to wear out; promptly; MAC Address deletion on other subsystems is to need the MAC Address on the wait subsystem 1 not lived by keep-alive; inform the mac address table administration module, on all subsystems, delete corresponding M AC address by the mac address table administration module.
But, the inventor finds can have a kind of aggregation port in two-layer network device, this aggregation port is a logical concept, it is the set of a series of physical ports, and the physics mouth in aggregation port can be on different subsystems, that is to say, aggregation port does not have information of home location, the ownership place of aggregation port is all subsystems in other words, the MAC Address of learning on aggregation port, corresponding output port are exactly an aggregation port, rather than certain physical port, like this, all subsystems are all had the right to initiate aging.
As seen; this moment is just inapplicable for common port MAC Address keep-alive principle; because aggregation port does not belong to any one subsystem (member's physics mouth of an aggregation port can simultaneously on a plurality of subsystems); if carry out keep-alive according to subsystem under the port; unless all these aggregation ports all have member port on all subsystems; and all ports can both be received and be used for the data flow of keep-alive; otherwise, must have on certain subsystem this corresponding MAC Address list item can not be by keep-alive.And; in this case; common port can not be vetoed " false aging " message by subsystem under judging port as handling " false aging "; so the mac address table administration module will be deleted this MAC Address of " can not delete " (the keep-alive flow that other subsystems have this aggregation port) originally; after MAC Address is deleted; with this MAC Address be the data flow of target MAC (Media Access Control) address will be on two-layer equipment inundation, increase the bandwidth occupancy rate.
