It should be appreciated that specific embodiment described herein is only used to explain the application, it is not used to limit the application.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutual any combination.
It is data pack transmission method flow chart provided in an embodiment of the present invention referring to shown in Fig. 2.The data packet transmission side
Method, including：
Step 201：The data packet for going to same destination is carried out packaging by uplink；
Wherein, the same destination specifically refers to which SA be sent to by switching network from the SA by data packet, goes to
The same SA is just destined to same destination.
Step 202：Cell is passed through choosing by scheduling by the cutting that the data packet after packaging is carried out to cell as a whole
The link selected is sent in switching network；
Step 203：Downlink caches the cell received from switching network, then carries out package-restructuring and unpacking processing；
Step 204：Data packet after unpacking is scheduled output.
Wherein, for going to, the data packet of same destination can be a packet or two packets are spelled in step 201
It connects, is also possible to multiple packets and is spliced.
Specifically, described that the data packet for going to same destination is subjected to packaging, including：
1) 1 packet is spliced and (carries out splicing to be equivalent to not splicing to 1 packet) or 2 packets splice, and
The packet of current 1 data packet for going to same destination can just go to same mesh when growing less than the first preset parameter value with the latter
The data packet on ground spliced.Such as the previous a length of N of data packet packet for going to same destination, go to same destination
The latter a length of M of data packet packet, and 2 packets are then combined into a whole packet less than the first preset parameter value by N, whole after packaging
Packet length is M+N, is a kind of special circumstances when M is equal to N, the whole packet length after packaging is 2*N certainly.Wherein, described
One preset parameter value can be configured according to actual system situation, application demand etc., and first preset parameter value can be with
For 144B, i.e., previous packet length can just be spliced when being less than 144B with the latter packet.
Using above-mentioned packaging method, have the characteristics that realize that logic is simple, and be able to satisfy application demand.It is default with first
Parameter value is 144B, for a length of 64B of most parcel, when carrying out packaging and unpacking, where the packet of second packet is first in cell
Position only appears in 64B~144B, without any position in cell, meeting in this realization to packaging and unpacking
It is simple more.
2) one or more parcels are spliced, but spliced several parcels is required to form a complete cell.Example
Such as, cell payload length is N, when continuously receiving the parcel that length is L, is at this time spliced n parcel, spliced packet
A length of n*L, and (n*L)<=N.
3) continuous packaging splices packet that is, as long as packaging length is less than the second parameter value, the packet of unlimited packaging
Number.The setting of second parameter value and Packet Forwarding Rate, system clock, cell tax, the relating to parameters such as link transmission bandwidth,
It needs to be calculated according to specific requirements, by taking the second parameter value is equal to 1024B as an example, it is assumed that a length of 64B of most parcel then at most may be used
16 packets are combined into a whole packet, i.e. the packet number range of packaging is 1~16.
Further, the uplink packaging rule can also include：
1) it is less than the packet of M (third parameter value) for length, it is unified to be handled according to M.Packet less than M first passes through filling nothing
Byte is imitated to M length, then carries out packaging processing again.When i.e. packet of the length less than M and other packets are spliced, the latter packet exists
Initial position in cell is mth byte.The long field of packet in the packet header of parcel is not modified, and is still small before indicating packaging
The physical length of packet.It when downlink unpacks, extracts the long field of packet and is judged, if packet is long to be less than M, according to length when handling
It is unpacked for M.
It is 144B with the first preset parameter value, for third parameter value M is 64B, when carrying out packaging and unpacking, second
Position where the packet of packet is first in cell only appears in 64B~144B, and without any position in cell, this is right
It can be simply more in the realization of packaging and unpacking.
2) data packet for participating in packaging, cannot be out-of-order after packaging, i.e., the packet first reached is located at the high ratio of the whole packet after packaging
Special position, the packet reached afterwards are located at the low bit position of whole packet.
3) packaging granularity is set, i.e., in the cell on packaging boundary, the initial position of next parcel needs what is met to want
It asks.Next parcel initial position calculation method (by taking packaging granularity is P as an example)：Previous parcel packet long-pressing P is that granularity is upward
It is rounded.Such as：When a length of L of previous packet, the initial position of next packet is [being rounded (L/P)+1] * P.
Wherein, packaging granularity is needed in the case where meeting packet transmission bandwidth, chooses maximum value.Because packaging granularity is got over
Greatly, first place is wrapped in cell sets the local fewer of appearance, such as：Packaging granularity is 32B, when maximum cell length is 256B, then
Packet first place, which is set, in cell only appears in the 0th, 32,64,96,128,160,192,224 byte, the realization that such packaging unpacks
It can be simply more.
Example：First parcel (A) wraps a length of 125B, and second parcel (B) wraps a length of 256B, according to the packaging granularity of 4B
Packaging, B packet initial position are：128B.
4) setting time-out configuration, time threshold is arranged in the time before current packet arrives to next packet, when being more than this
Between thresholding will be no longer waiting for next packet and carry out packaging, directly will currently wrap carry out subsequent processing.
After the completion of packaging, the whole packet after packaging carries out the cutting of cell, and cutting mode may include：
If maximum cell length is Max, minimum cell length is Min, wraps a length of L.
The determination of maximum cell and minimum cell and total system scheme architecture design have relationship, can be according to using need
It asks and is set.It is 256B with maximum cell length, for minimum cell length is 128B, for wrapping the packet of a length of 1000B, then
Packet is cut into 4 cells, cell length is respectively：256B, 256B, 256B, 232B.
It is less than the packet of Max for length, a cell directly is dressed up into whole encapsulating.
If packet is long to be equal to n*Max, packet is directly cut into the cell that n length is Max.
If packet is long to be equal to (n*Max)+r, and r is more than or equal to Min, then is cut into cell and one that n length is Max
Length is the cell of r.
If packet is long to be equal to (n*Max)+r, and r is less than Min, then is cut into the cell that n-1 length is Max, one long
The cell that degree is Max/2 and the cell that a length is (Max/2+r).
Wherein, n is the natural number more than or equal to 1, and r is the natural number more than or equal to 1.
Packet after cutting is as cell payload.
Cell length, packaging instruction and the label information for being used to recombinate are loaded into header, by header and cell
Payload is scheduled output as a cell.
The packaging instruction, including：First packet position instruction and useful signal and packet tail eop identifier, it is seen then that in uplink
When cutting cell, first packet position instruction and useful signal and packet tail eop identifier are added in header, are used for downlink solution
Packet.
In step 202, in downlink, the cell received from switching network is cached, then carries out package-restructuring and unpacking
Processing, and the data packet after unpacking is scheduled output.
During specific implementation, since data packet between the cell of different data packet by will appear after switching network
Interweave, after several cells of same data packet cutting may also have by the time of different links arrival downlink and first have, because
This needs to carry out package-restructuring to data packet.
To data packet carry out package-restructuring method include：
The cell received is cached, and extracts the label information in header, then by label information and letter
The storage location of member divides link to carry out queue caching together, is then compared by label information, the cell that will be sent at first
Scheduling output, completes cell order maintaining, i.e., by label information, cell is successively dispatched to output, to realize package-restructuring.
The cell of caching can be only comprising cell payload, i.e., the data after removing header, while conciliating in package-restructuring
It is cached before packet, as shown in figure 5, parcels multiple in this way only take up a spatial cache, to save spatial cache, is improved slow
Deposit utilization rate.
After data packet completes package-restructuring, unpackaging operation is carried out to whole packet, the step of unpacking includes：
1) the first position in cell of packet that practical first packet is obtained according to first packet position instruction, is wrapped further according to first
Package informatin, extract first packet packet it is long.
As it can be seen that the information that unpacking needs are used includes：First packet position instruction and useful signal may have in one cell
Parcel data packet packet is first, it is also possible to which first without data packet packet, when there is data packet packet head, it is 1 that packet first place, which is set effective signal,.
2) packet is long extracts：The long initial position for calculating next data packet of the packet wrapped according to upper one, then according to packet header
The packet long message of middle carrying, the packet for successively extracting the data packet in packaging is long, and the packet then after read group total packaging is long, big packet
It is long to detect number of slices for wrapping, to detect the long splicing correctness of packet.When being provided with packaging granularity, next packet initial position
Preparation method (by taking packaging granularity is P as an example) is：Upper parcel packet long-pressing P rounds up for granularity.
3) packet tail is obtained according to packet tail eop identifier, this packet tail indicates the packet tail of whole packet after packaging.Work as eop=1, indicates
Current cell is the tail cell of whole packet.
Each cell of packet after unpacking is successively read into then scheduling output by group packet sequence from caching.
Due to there is a packaging, i.e. in a cell there are two or several parcels, therefore a cell addresses need it is multiple
Team out such as needs can just carry out address recycling after all exporting at all parcels.As shown in fig. 6,2 parcels are spliced into a whole packet,
And it has been cut into a cell, and it is all when dispatching output since caching is cached according to cell, it needs to repeat to read the letter
Twice, one small packet scheduling output is read every time in first address.
