Wherein, said first integrated circuit board also comprises after on second integrated circuit board of MAC table capacity maximum in the network of said DLF message redirecting to said first integrated circuit board place:
In the MAC of said second integrated circuit board table, search the target MAC (Media Access Control) address of said DLF message;
If there is not the target MAC (Media Access Control) address of said DLF message in the MAC of said second integrated circuit board table; Then said DLF message is broadcasted in the network of said first integrated circuit board place; Otherwise, said DLF message is sent to said target MAC (Media Access Control) address purpose of indicating port, and sends with the mode of clean culture.
Wherein, the step of said DLF message being broadcasted in the network of said first integrated circuit board place is preferably: said DLF message all of the port in said first integrated circuit board place VLAN is broadcasted.
Because the MAC Address in the MAC table of the integrated circuit board that MAC table capacity is maximum is maximum; Therefore; When an integrated circuit board confirms that the data message of its reception is the DLF message; On the integrated circuit board that this DLF message redirecting to this MAC table capacity is maximum, show the target MAC (Media Access Control) address that the maximum integrated circuit board of capacity is searched this DLF message again by this MAC, the probability that finds like this is just very big; In case find the target MAC (Media Access Control) address of this DLF message; Just this DLF message is sent to the indicated destination interface of this target MAC (Media Access Control) address; Have only when the maximum integrated circuit board of this MAC capacity does not find the target MAC (Media Access Control) address of this DLF message yet, just broadcast, significantly reduced the probability that data message is broadcasted like this; Finally save the waste of port bandwidth, improved systematic function.
In addition, broadcast and go out, form broadcast storm, need carry out two layers of isolation, guarantee to flow out from the port again from the stream that the port gets into to source port self from source port for fear of final DLF message; Before said DLF message was broadcasted in said first integrated circuit board and said second integrated circuit board place network, also comprise: the port to said first integrated circuit board was isolated.
Specifically, as being provided with in the port isolation list item to said first integrated circuit board: the direction of sending message from this port is a channel status, and the direction that message gets into this port is a blocking state.
In addition, when not having the target MAC (Media Access Control) address of said DLF message in the MAC table as if said second integrated circuit board, also comprise: the source MAC of said DLF message is joined in the MAC table of said second integrated circuit board.During concrete the realization; As can be to open the source mac learning function of second integrated circuit board (being the maximum integrated circuit board of MAC table capacity) to the redirection message of the target MAC (Media Access Control) address that also do not have data message in this type second integrated circuit board; The source MAC that is about to this data message joins in the MAC table of said second integrated circuit board, like this, and when the target MAC (Media Access Control) address of a data message is identical with this source MAC; This second integrated circuit board can be directly with this data message forwarding to this source MAC port pointed; This second integrated circuit board just need not be searched in its MAC table again, has improved the probability that the data message target MAC (Media Access Control) address hits, and has also improved the operating efficiency of integrated circuit board simultaneously.
In addition, in said method, when confirming that said data message is address searching failure DLF message, also comprise: in the header field of said DLF message, being provided for this message of mark is the sign of DLF message.When another processing unit of this integrated circuit board,, when receiving a data message, just can be easy to confirm whether this data message is the DLF message according to the header field of this data message like transmitting element.
Combine Fig. 1 that the concrete realization of said method of the present invention is described below again:
The MAC table capacity of integrated circuit board 1 is 16K, and the MAC table capacity of integrated circuit board 2 is 32K, and the MAC table capacity of integrated circuit board 3 is 16K, and the MAC table capacity of integrated circuit board 4 is 16K;
The integrated circuit board of selecting MAC table capacity maximum in the system is an integrated circuit board 2; MAC table capacity utilizes redirection function to be established to the redirected rule of integrated circuit board 2 less than all the other integrated circuit boards (like integrated circuit board 1,3 and 4) of integrated circuit board 2; On MAC table capacity all the other integrated circuit boards, each port is set isolates from going up in two layers less than integrated circuit board 2;
1) when the Port 1 of integrated circuit board 1 receives a data message, checks at first whether its target MAC (Media Access Control) address exists in the MAC of integrated circuit board 1 table;
2) if exist, then be forwarded to destination interface according to normal forwarding process; If do not exist; Then data message is utilized the message redirecting function that 1 chip provides on the integrated circuit board; This data message is redirected on the integrated circuit board 2 of MAC table capacity maximum in the system, carries out the quadratic search of the target MAC (Media Access Control) address of said data message, can improve and search hit probability;
In this step, need set up the redirected rule that is redirected to integrated circuit board 2 on less than the integrated circuit board of integrated circuit board 2 at these MAC table capacity.Whether this rule has comprised and has been used to discern a bag is the relevant field combination of DLF message; This field is when integrated circuit board 1 judges that its data message that receives is the DLF message; In the packet header of this data message one sign is set, being used for this data message of mark is the DLF message, behind another processing unit (like transmit port) of this this integrated circuit board 1 of data message entering; This processing unit can be resolved the packet header of data message; Extract relevant field, whether see and above-mentioned rule match, if mated; Then explanation is the DLF message, and this DLF message will be redirected to integrated circuit board 2 and do the secondary purpose and search;
3) if in the MAC of integrated circuit board 2 table, still do not find the target MAC (Media Access Control) address of above-mentioned data message, again this data message is broadcasted in corresponding VLAN; If find, then clean culture is forwarded to destination interface;
If in the integrated circuit board 2; The target MAC (Media Access Control) address of said data message is searched still failure, broadcasts and goes out from source port for fear of final DLF message, forms broadcast storm; Must carry out two layers of isolation to source port self, guarantee to flow out from the port again from the stream that the port gets into.
4) after the exchange chip on the integrated circuit board 1 (MAC table capacity is less than the integrated circuit board of integrated circuit board 2) is received a data message, judge whether it is the DLF message.If DLF bag; Then open source mac learning function on the integrated circuit board 2 to such redirection message; After receiving redirected DLF message of coming; Search the MAC table of this integrated circuit board exchange chip, if find then the DLF message is forwarded to destination interface, if still do not find purpose MAC then this DLF message is broadcasted in corresponding VLAN; Otherwise, normally transmit this and wrap to destination interface;
Wherein, After integrated circuit board 2 receives the redirected DLF message of coming of other integrated circuit board; Open the learning functionality of source MAC on integrated circuit board 2 in this type of message; So just increase MAC Address capacity less integrated circuit board carries out the purpose MAC of the DLF message that the secondary purpose searches on integrated circuit board 2 the probability that hits, be equivalent to expand the mac address table capacity of integrated circuit board 2.Thereby reduced the probability that the DLF message is broadcasted in VLAN.
Certainly, in the foregoing description, if the MAC table capacity of integrated circuit board 1 is 16K, the MAC table capacity of integrated circuit board 2 is 32K, and the MAC table capacity of integrated circuit board 3 is 64K, and the MAC table capacity of integrated circuit board 4 is 16K;
Under such situation,, and judge when this data message is the DLF message if integrated circuit board 1 receives a data message; Can (be that MAC table capacity promptly is not maximum with this DLF message redirecting to integrated circuit board 2; Neither be minimum), after integrated circuit board 2 receives the next data message of this integrated circuit board 1 forwarding, if the target MAC (Media Access Control) address of this data message of judgement is not also in the MAC of this integrated circuit board table; Then this integrated circuit board 2 can directly be broadcasted this data message; Also can further this data message be redirected to integrated circuit board 3, if find, then directly with data message forwarding to destination interface;
After integrated circuit board 3 receives the data message that this integrated circuit board 2 forwards, also in the MAC of this integrated circuit board 3 table, search the target MAC (Media Access Control) address of the data message that this integrated circuit board 2 forwards,, then broadcast again,, then directly send to destination interface if having if do not have;
Certainly, most preferred mode is: integrated circuit board 1 directly with on the DLF message redirecting of judging to this integrated circuit board 3 (be MAC [integrated circuit board that capacity is maximum), can increase the hit rate of data message purpose MAC so to the full extent, reduces the probability that data message is broadcasted.
As shown in Figure 3, embodiments of the invention also provide a kind of integrated circuit board 30, comprising: first port 31 and second port 32; And
Be redirected unit 34, be used to produce instruction on MAC table another integrated circuit board capacious of the said integrated circuit board of said DLF message redirecting to MAC table Capacity Ratio;
