Description
Technical field
The present invention relates to the study and the aging technology of medium access control (MAC) address in the distributed Ethernet switch, relate in particular to a kind of distributed Ethernet switch and inner MAC Address maintaining method thereof.
Background technology
Ethernet switch is the multiport networking equipment that is operated in the second layer (data link layer) of open system interconnection (OSI, Open System Interconnection).Packet enters from a port of Ethernet switch, Ethernet switch is based on the purpose medium access control (MAC in the packet, MediaAccessControl) MAC of address and self internal maintenance transmits, obtain output port of data packet, then packet is forwarded from outbound port.It is that Ethernet switch is realized the core component that packet is transmitted that the MAC of Ethernet switch internal maintenance transmits, and MAC transmits and learns each newfound MAC Address and automatic aging automatically by Ethernet switch and fall all inactive MAC Address and set up.
High-end Ethernet switch adopts distributed structure/architecture more at present, is called distributed Ethernet switch, promptly includes a plurality of ply-yarn drills, and a plurality of ports and an exchange chip are arranged on each ply-yarn drill.Packet can enter from a port on one of them ply-yarn drill, and another port from same ply-yarn drill exchanges away, and this exchange is called local switch mode; Packet also can enter from a port on one of them ply-yarn drill, and a port from another ply-yarn drill exchanges away, and this exchange is called strides the card switch mode.This shows, must keep identical MAC to transmit on each ply-yarn drill of distributed Ethernet switch.
At present, be used for realizing distributed Ethernet switch MAC address learning and aging technology, mainly comprise two types.
A kind of is " common study is concentrated aging " type, and each ply-yarn drill in the promptly distributed Ethernet switch can be learnt MAC Address, and is shared with other ply-yarn drills after study; Inactive MAC Address during MAC in each distributed Ethernet switch on responsible concentrated aging all ply-yarn drills of personal module of existence transmits.
For example: Chinese patent is disclosed on May 14th, 2008, publication number is CN101179514, denomination of invention is the patent application of " MAC item of distributed network processing system maintaining method and attending device ", " common study; concentrate aging " technology is applied to comprise the distributed network processing system of an interface board and a plurality of business boards, have only ports having on the interface board in this system, MAC transmits on each plate to be had.Each business board can be learnt MAC Address in this system, and the aging of MAC Address then is responsible for by interface board.Because in the specific environment that this patent application was suitable for, interface board finally is responsible for receiving and dispatching all packets, so every the record of interface board in can transmitting MAC maintains easily.But for this applied environment of distributed Ethernet switch, do not have no matter which independent card (is ply-yarn drill, still be main control card) can touch all packets through system forwards, thereby the MAC Address that realizes " common study is concentrated aging " mode in distributed Ethernet switch safeguards it is the comparison difficulty.

Embodiment
The technical solution of the present invention is further elaborated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the distributed Ethernet switch that is suitable for of MAC Address maintaining method of the present invention need possess following feature:
A, distributed Ethernet switch inside comprise N (N 〉=1) individual ply-yarn drill and 1 main control card;
Comprise a plurality of switching ports on b, each ply-yarn drill, for example: port one, port 2, port 3, port 4, port 5 and port 6; Between ply-yarn drill and the main control card, and communicate by interconnect port (as port 0) between the ply-yarn drill, and ply-yarn drill is supported this locality exchange of packet and is striden the card exchange;
Safeguard all on c, each ply-yarn drill and the main control card that a MAC transmits.
MAC Address maintaining method by the present invention's distributed Ethernet switch shown in Figure 1 is realized as shown in Figure 2, mainly may further comprise the steps:
That is to say that the packet that the ply-yarn drill in the distributed Ethernet switch only enters the switching port from this ply-yarn drill is learnt its MAC Address; And, do not learn its MAC Address to the data that the interconnect port from this ply-yarn drill enters.Thereby a packet only allows the ply-yarn drill of first this packet of processing to learn its MAC Address from entering distributed Ethernet switch to the process that is forwarded away (leaving distributed Ethernet switch).
The ply-yarn drill of learning MAC Address is constructed the learning information of corresponding MAC Address, and main control card and other ply-yarn drills in the distributed Ethernet switch are given in announcement.The learning information of the MAC Address of structure comprises: MAC Address of learning and port information.Main control card and other ply-yarn drills are according to the learning information of the MAC Address of being announced, and separately MAC is transmitted upgrade processing.
In addition, MAC Address among the present invention can be the source MAC or the target MAC (Media Access Control) address of packet, but be preferably the source MAC of packet,, can show more that just the owner of this source MAC is movable because when only receiving a packet from source MAC; And receive a packet of going to target MAC (Media Access Control) address, whether the owner that but can not reflect this target MAC (Media Access Control) address more accurately movable (may not exist).
From MAC Address maintaining method shown in Figure 2 as can be seen, the strategy that the present invention adopts a kind of " whose study; who is aging; whose announcement ", after promptly learning MAC Address by certain ply-yarn drill, to be responsible for wearing out by this ply-yarn drill, and be responsible for announcing the learning information and the ageing information of this MAC Address, with the consistency of safeguarding that MAC transmits on all integrated circuit boards to main control card and other ply-yarn drills.And by adopting above-mentioned strategy, its operation that realizes the MAC Address maintenance is simple relatively, can simplify the processing logic of distributed Ethernet switch; Because it is little to be used to safeguard that MAC on each integrated circuit board transmits conforming communication overhead, therefore can reduce the communication between plates burden in the distributed Ethernet switch.
Be example with a certain ply-yarn drill X in the distributed Ethernet switch below, the learning process of MAC Address further elaborated, as shown in Figure 3, mainly may further comprise the steps:
Certain ply-yarn drill X in the step 301, distributed Ethernet switch receives packet from switching port, and according to the MAC Address of learning from packet, the MAC that searches self transmits.

In an embodiment of the present invention, can wear out (AGING) identifies as first, and can not wear out (UNAGING) is as second sign.For the list item that is designated AGING, the MAC Address that shows this list item correspondence is that ply-yarn drill X learns from switching port, and ply-yarn drill X can carry out burin-in process to this list item voluntarily; For the list item that is designated UNAGING, the MAC Address that shows this list item correspondence is not that ply-yarn drill X learns from switching port, and ply-yarn drill X can not carry out burin-in process to this list item voluntarily, and can only be according to the announcement of other ply-yarn drills, passive execution burin-in process.
Thereby if ply-yarn drill X judges that in the list item that mates be AGING, then execution in step 304; Otherwise, execution in step 305.
Step 304 is AGING in the list item of ply-yarn drill X judgement coupling, shows that corresponding MAC Address is that ply-yarn drill X learns from switching port, only need refresh the timestamp in this list item, and is refreshing the whole flow process of back end that finishes.
Be UNAGING in the tag field of list item, and ply-yarn drill X receives from the packet that mates corresponding MAC Address the list item from its switching port, show that then migration has taken place MAC Address, for example: originally the packet of MAC1 enters distributed Ethernet switch from the port one of ply-yarn drill Y, and now the packet of MAC1 enters distributed Ethernet switch from the port 3 of ply-yarn drill X.
The learning information of the MAC Address of structure need comprise: mac address information of learning and port information.
Tag field was the MAC Address of AGING during ply-yarn drill X transmitted the MAC of its maintenance, can carry out burin-in process voluntarily: stab according to these MAC Address time corresponding and calculate expired time, and when expired time exceeds the ageing time of setting, judge that MAC Address is expired; Thereby expired MAC Address is carried out burin-in process, and the ageing information of constructing the MAC Address of carrying expired MAC Address is announced to main control card and other ply-yarn drills, by main control card and other ply-yarn drills ageing information, carry out the burin-in process that MAC separately transmits according to MAC Address.
