Embodiment
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
The flow chart that fragment message is recombinated that Fig. 3 provides for the embodiment of the invention one, as shown in Figure 3, its concrete steps are as follows:
Step 301: the same reconstructing interface board selection principle of configuration on each interface board of receiving equipment.
Reconstructing interface board selection principle can be: in may receiving the total interface plate of burst, with the interface board of plate minimum as reconstructing interface board; Perhaps, in may receiving the total interface plate of burst, as reconstructing interface board, at this moment, master control borad needs periodically the load information of total interface plate is sent to each interface board with the interface board of load minimum; Perhaps, source IP address and/or the purpose IP address and/or the protocol number etc. of burst are carried out Hash (hash) computing, in may receiving the total interface plate of burst, interface board that will be corresponding with the hash operation result is as reconstructing interface board.
Step 302: the interface board on the receiving equipment receives burst, in the routing table of self preserving, searches the corresponding route of source IP address of carrying with this burst.
Step 303: interface board judges whether lookup result is equal-cost route, if, execution in step 304; Otherwise, execution in step 308.
In the embodiment of the invention, equal-cost route refers to the route that has one or more from the source device to the receiving equipment, is called equal-cost route between these routes mutually; The non-equivalence route refers to and only have a route from the source device to the receiving equipment.
Step 304: interface board judges whether all outgoing interfaces of the equal-cost route that finds all are positioned on the interface board, if, execution in step 308; Otherwise, execution in step 305.
Preserve the corresponding relation of outgoing interface information and interface board number on each interface board, interface board is according to this corresponding relation, can determine whether all outgoing interfaces of the equal-cost route that finds are positioned on the interface board.
Step 305: interface board is according to pre-configured reconstructing interface board selection principle, in the interface board of all outgoing interface correspondences of the equal-cost route that finds, selects an interface board as reconstructing interface board.
When reconstructing interface board selection principle is: in may receiving the total interface plate of burst, with the interface board of plate minimum during as reconstructing interface board, the interface board that receives burst only needs in the interface board of all outgoing interface correspondences of the equal-cost route that finds, and the interface board of option board minimum gets final product as reconstructing interface board.
Distinguishingly, since receiving equipment with send the routing table of preserving on the source device of this burst or the middle forwarding unit may be inconsistent, the interface board that might cause receiving burst is not in the interface board of all outgoing interface correspondences of the equal-cost route that finds any one, at this moment, consider that other interface board on the receiving equipment can't learn that according to routing table described interface board can receive burst, therefore, all interface boards that receive burst will be benchmark with the interface board of determining according to equal-cost route still, determine reconstructing interface board.For example: establish preestablish the plate minimum interface board as reconstructing interface board, if a message comprises 4 bursts: burst 1～4, wherein: burst 1,3 arrives receiving equipment by interface board 1, burst 2,4 arrives receiving equipment by interface board 2, outgoing interface information on the receiving equipment in the equal-cost route corresponding with the source IP address of these 4 bursts is then indicated: the outgoing interface of the burst of this message is positioned on interface board 2 and 3, then the interface board of interface board 1 and 2 option board minimum in interface board 2 and 3: interface board 2 is as reconstructing interface board.
When reconstructing interface board selection principle is: in may receiving the total interface plate of burst, with the interface board of load minimum during as reconstructing interface board, the interface board that receives burst only need be according to the load information of up-to-date each interface board sent of master control borad, in the interface board of all outgoing interface correspondences of the equal-cost route that finds, the interface board of selecting the load minimum is as reconstructing interface board.
When reconstructing interface board selection principle is: source IP address and/or purpose IP address and/or protocol number etc. to burst carry out the hash computing, in may receiving the total interface plate of burst, interface board that will be corresponding with the hash operation result is during as reconstructing interface board, the interface board that receives burst only needs source IP address and/or the purpose IP address and/or the protocol number etc. of burst are carried out the hash computing, then the hash operation result is mapped on the interface board in the interface board of all outgoing interface correspondences of the equal-cost route that finds, with this interface board as reconstructing interface board.For example: the outgoing interface of establishing the equal-cost route that interface board finds according to the source IP address of burst is positioned at 3 interface boards: on the interface board 2～4, if the source IP address of this burst is 1.2.3.4, purpose IP address is 2.3.4.5, each interface board that then receives this burst carries out the hash computing to this source IP address and purpose IP address, hash=(1+2+3+4+2+3+4+5) %3=0, determine that then interface board 2 is a reconstructing interface board, wherein, a among the %a represents the interface board sum of the outgoing interface correspondence of the equal-cost route that finds.
Step 306: interface board sends to reconstructing interface board with the burst that receives.
If reconstructing interface board is self, then interface board need not to send burst.
Step 307: reconstructing interface board receives the burst that other interface board is sent, and according to the side-play amount in this burst and the burst self received, all bursts is recombinated, and this flow process finishes.
Because the reconstructing interface board selection principle that disposes on each interface board is identical, therefore, for same message, the determined reconstructing interface board of each interface board of different bursts that receives this message is with identical, guaranteed that reconstructing interface board will obtain all bursts of message, thereby made the message reorganization reliably to carry out.
After reconstructing interface board is finished the fragment message reorganization, the message after the reorganization is sent to upper layer entity handle.
Step 308: interface board determines self will receive all bursts of this message, and the burst that receives is recombinated.
Distinguishingly, when interface board judges that the route that the source IP address according to burst finds is the non-equivalence route, perhaps, the route that finds is that equal-cost route but all outgoing interfaces are when only being positioned on the interface board, if the interface board of outgoing interface correspondence that detects described non-equivalence route or described equal-cost route simultaneously when self not being same interface board, then sends to this burst on the interface board of outgoing interface correspondence of described non-equivalence route or described equal-cost route and recombinates.
In addition, in actual applications, when reconstructing interface board selection principle is: source IP address and/or purpose IP address and/or protocol number etc. to burst carry out Hash (hash) computing, in may receiving the total interface plate of burst, interface board that will be corresponding with the hash operation result is during as reconstructing interface board, after interface board receives burst, can not search the action of routing table, directly source IP address and/or purpose IP address and/or the protocol number etc. to burst carry out the hash computing, then this operation result is mapped on the interface board number, with this interface board corresponding interface plate as reconstructing interface board.For example: establish receiving equipment and have 4 interface boards: interface board 0～3, if the source IP address of the burst that interface board is received is: 1.2.3.4, then this source IP address is carried out hash computing: hash=(1+2+3+4) %4=2, then with interface board 2 as reconstructing interface board, wherein, a among the %a represents the interface board sum on the receiving equipment.
As can be seen: the message that adopts the load balancing mode to transmit of not being only applicable to embodiment illustrated in fig. 3 is equally applicable to the message that does not adopt the load balancing mode to transmit.
In addition, because the user can be according to the network design environment, learn that in advance which path will adopt the load balancing mode to transmit message, and which path will not adopt the load balancing mode to transmit message.The dispersion recombination form that can adopt the present invention to mention in embodiment illustrated in fig. 3 for the message that adopts the load balancing mode to transmit carries out the message reorganization, then can adopt concentrated recombination form of the prior art to carry out the message reorganization for the message that does not adopt the load balancing mode to transmit.Like this, the user can with packet route information as: source IP address and/or purpose IP address and/or protocol number etc. are configured on the receiving equipment with the recombination form of supporting, interface board is after receiving burst like this, at first according to source IP address and/or the purpose IP address and/or the protocol number etc. of this burst, determine to adopt and concentrate recombination form still to disperse recombination form to recombinate, concentrate recombination form if adopt, then burst is sent to master control borad and recombinate; Disperse recombination form if adopt, then adopt method shown in Figure 3 to recombinate.
The flow chart that fragment message is recombinated that Fig. 4 provides for the embodiment of the invention two, as shown in Figure 4, its concrete steps are as follows:
Step 401: the corresponding relation of routing information such as configuration source IP address and/or purpose IP address and/or protocol number and recombination form information on receiving equipment in advance, and on each interface board of equipment, dispose same reconstructing interface board selection principle.
Recombination form comprises: concentrate reorganization and disperse reorganization.
The corresponding relation with recombination form information such as source IP address and/or purpose IP address and/or protocol number etc. can be configured in the access control list (ACL).
Step 402: interface board is received burst, according to source IP address and/or the purpose IP address and/or the protocol number etc. of this burst, judges that this burst is to support to concentrate recombination form or dispersion recombination form, if support to concentrate recombination form, execution in step 403; If support to disperse recombination form, execution in step 404.
Step 403: interface board sends to master control borad with this burst, carries out the burst reorganization by master control borad and handles, and this flow process finishes.
Step 404～410 are identical with step 302～308.
It is pointed out that the equipment mentioned in the embodiment of the invention can be the destination device that message arrives, also can be to E-Packet and the forwarding unit of virtual support burst reorganization.Because forwarding unit may network enabled address transition (NAT), IP packet safety detection (IPSec), dynamic firewall (ASPF) wait business, when forwarding unit is received fragment message, carry out described Business Processing to each burst; In all bursts of a message, first burst that sends of active equipment is promptly: comprise source/destination slogan information in first, and when each burst is carried out above-mentioned Business Processing, all to use this source/destination slogan information, therefore must guarantee: all bursts can both be handled on same interface board, so that interface board can be from first acquisition source/destination slogan information, and be used for the above-mentioned Business Processing of all bursts.Will be owing to carrying out above-mentioned Business Processing and burst is focused on situation on the same interface board be called virtual burst reorganization to burst.
