Those of ordinary skills hold is intelligiblely, interweaving scheduling between multichannel is the different scheduling mode of whole packet scheduling between a kind of and multichannel, in the scheduling that interweaves, each passage message to be sent is divided into fragment, first select a passage to send a fragment of message in this passage, then select another passage to send a fragment of message in this passage, so circulate, the selection that interweaves, repeats no more this present embodiment.
At the second receiving terminal, for each receive path:
The appointed information of S203, reception message, and,
S204, according to described appointed information and the message fragment that receives successively, the corresponding Frame of current receive path is filled, to complete the encapsulation to described Frame.
In the present embodiment or the present invention some other embodiment, preferred:

Below in conjunction with concrete scene, the present invention is further described.
At SDH(Synchronous Digital Hierarchy, SDH (Synchronous Digital Hierarchy)), PDH(Plesiochronous Digital Hierarchy, accurate synchrodata system), OTN(Optical Transport Network, optical transport network) etc. in network, in order to realize the transmission of customer data, can adopt generic framing procedure, GFP (GFP, Generic Framing Procedure), first customer data is packaged into GFP Frame, according to ITU-T suggestion, (ITU-T G.707 again, ITU-T G.8040, ITU-T is G.709) in be defined in SDH, PDH, on OTN network, carry out concurrent transmission.
GFP Frame is byte-aligned, shown in Figure 3, core heading (Core Header) and payload section (Payload area), consists of.Core heading (Core Header) is indicated again the verification bit(cHEC of territory (payload length indicator) and 16bit by the message length of 16bit) form; Payload section (Payload area) consists of payload head (Payload headers), customer data (Client payload information field), FCS verification territory (Optional payload FCS) again, further can be shown in Figure 4.Before encapsulation gfp frame, need to first obtain the length information of customer data.
In prior art, DP chip and OTN chip communication modes are shown in Figure 5.DP chip is connected by Interlaken interface with OTN chip.DP chip be take single message and at each interchannel, is carried out whole packet scheduling as granularity, selects a passage to send a message, and then selects another passage to send a message.After each passage of OTN chip receives message, will carry out the buffer memory of whole message, until that the current message in this passage receives is complete, then calculate message length territory, and message length territory and message data are packaged into the Frame of GFP form.
Fig. 6 is DP chip and OTN chip communication schematic diagram in the embodiment of the present invention three.In the present embodiment:
DP chip changes at each interchannel the scheduling mode that interweaves into, at each interchannel, take the message fragment of certain length (such as be mapped to the message data length of OTN pipeline at every turn) and carry out the scheduling that interweaves between message as granularity, and before in advance each message length information being placed on to start of message (SOM) position (for example, in two bytes before start of message (SOM) position), by Interlaken interface, message length information and whole message are below sent to OTN chip.DP chip itself disposes larger buffer memory because of the needs of function, thus message to be sent can global storage in the buffer memory of DP chip, in this buffer memory, calculate the length of message to be sent.
When each passage of OTN chip receives message, what first receive is message length information, then wait for that the message fragment data accumulation receiving reaches some degree of depth (also can be described as and start waterline) in the corresponding buffer memory of prepass, just can open the encapsulation of GFP Frame, the message length obtaining and the message fragment of taking out from buffer memory are filled to corresponding GFP Frame, along with transmitting terminal is sent message fragment successively, receiving terminal also ceaselessly takes out message fragment from buffer memory, this GFP Frame is filled continuously, until the whole fillings of current message are complete, complete encapsulation.Because the filling of Frame is a continuous process, can not interrupt, thus while starting, need to first wait for that the message fragment data accumulation in buffer memory reaches some degree of depth, then open filling process.
When the transmitting terminal in the present embodiment sends message to receiving terminal, the single message of no longer take sends as unit, but message is decomposed, change into and take the message fragment of designated length and send as unit, and the required appointed information (as message length) of first transmitting and receiving terminal while sending, thereby make receiving terminal not need again the whole message of buffer memory, solved the problem that the cache resources of receiving terminal is taken in a large number.
