With the high speed development of internet, network equipment ground performance is also faced with and gravely tests, the treatment of fragment message
Ability is an important indicator of the performance for weighing the network equipment.
Under normal circumstances, the size of the former message for being sent when sender's network equipment is more than MTU (Maximum
Transmission Unit, MTU) when, it is possible to burst treatment is carried out to sent former message, then will be every
The burst side-play amount of individual fragment message is write into the header of the fragment message, then again by these fragment messages send successively to
Recipient's network equipment, carries out correspondingly fragment message and recombinates by recipient's network equipment.
After recipient's network equipment receives fragment message, the fragment message can be cached into buffer area.Referring to
Fig. 1, Fig. 1 are the schematic diagrames of the mapping format of the fragment message in a kind of recipient's network equipment buffer area shown in the application.
Under normal circumstances, the header of the fragment message that recipient's network equipment will can be received and fragment message data institute
In the address write-in SKB of buffer area (i.e. data field), and the buffer area that the data write-in of the fragment message is recorded with the SKB
In the corresponding buffer area in address (i.e. data field).
Because after above-mentioned former message is fragmented, each fragment message has the header of oneself, and is route in selection
When with other fragment message independences.So, when these fragment messages reach recipient's network equipment, it is possible that out of order
Problem, in other words, the order of fragment message cached in the buffer area for being exactly recipient's network equipment is not this point
Order of the piece message in the former message.
For example, the former message is split into first, second to n-th fragment message by sender's network equipment, and will
This first, second to n-th fragment message are sent to recipient's network equipment successively.
But, because the selected route of each fragment message is different, link-quality is different so that recipient's network equipment
The order of the fragment message for receiving is not first, order as second to n-th fragment message, for example, receiving
The order of the fragment message that side receives may be first, the 4th, the 3rd, second fragment message etc..
Therefore, recipient's network equipment needs to recombinate the fragment message for receiving, and reformulates the former message,
Correspondingly Business Processing (such as NAT, protocol depth detection) can be carried out to the former message.
Referring to Fig. 2, Fig. 2 is that Fig. 2 shown in related IP message recombining methods is a kind of correlation technique shown in the application

The fragment message burst side-play amount, in an orderly manner by the data of the fragment message in buffer area be copied to successively one section it is continuous
In physical memory so that what is stored in the continuous physical memory is complete former message.
However, in the recombinant technique of fragment message in the related art, when being recombinated to fragment message, recipient's network
Equipment needs each fragment message to be copied to above-mentioned continuous physical memory from buffer area that (this process can also be referred to as
Memory copying), because the number of times that memory copying occurs is excessive, so having had a strong impact on the performance of equipment, considerably increase message
The time delay of forwarding.
The application proposes a kind of processing method of fragment message, and the fragment message that the network equipment will can be received is stored up respectively
Deposit to corresponding buffer area, the buffer area includes header region and data field.And the header region note of each fragment message can be based on
The burst side-play amount of record, the address-ordered of the data field of each fragment message is linked as corresponding logic chained list.The network equipment
The logic chained list can be based on, corresponding Business Processing be carried out to each fragment message, and after processing is completed, patrolled based on described
Chained list is collected, each fragment message is forwarded to the next stage network equipment successively.
When fragment message is recombinated, because the fragment message that the network equipment will no longer be stored in buffer area is copied in an orderly manner
In continuous physical memory, and the burst side-play amount that the header region that can be based on each fragment message records, by each fragment message
Data field address-ordered be linked as corresponding logic chained list, the fragment message in buffer area is reassembled into the upper original of logic
Message, such that it is able to efficiently reduce the number of times of copy.Therefore the performance of equipment can be effectively improved, message forwarding is reduced
