Embodiment Construction

[0039] Below in conjunction with the accompanying drawings, the implementation of the technical solution is described in further detail basically in the order of the accompanying drawings:

[0040] Fig. 1 is the framing multi-channel system diagram of the present invention, is used for explaining the connection relation of each channel of framing, for each channel, the direction of data flow is to enter channel scheduling processor earlier, then data is sent into data buffer 1 again, and then sent After processing, the data is sent to the data buffer 2, and then output to the channel scheduling processor.

[0041] Fig. 2 is single-channel framing data processing flow chart of the present invention, has illustrated the data processing flow when PPP (point-to-point, the same below) packet is transformed into advanced link control procedure data packet in single-channel, comprises character escape, fast Frame check sequence FCS calculation.

Abstract

The method for implementing high-grade link control protocol frame treatment includes framing and deframing processes. The described framing process includes the following steps: receiving a piece of data transferred from exterior and identification number of said user; temporarily storing the data into data buffer memory; fetching a byte of data from data buffer memory by data processing machine; escaping said byte data and resolving frame correction sequence (FCS); judging that the processed data byte number can meet some set threshold value y or not, if it can meet said threshold value, feeding the data byte number into the next data buffer memory, if it can not meet, judging that the piece of data is processed completely or not, if it is not, returning to third step, if it is processed, executing next step, the data in the second data buffer memory can be outputted by means of channel dispatcher.

Description

Technical field: [0001] The invention relates to the field of digital communication, and realizes an advanced link control procedure frame processing method, in particular to a multi-channel multi-user fast advanced link control procedure frame processing method. Background technique: [0002] RFC1662 (PPP in HDLC-like framing) proposes an advanced link control protocol processing method for realizing synchronous bit stream and asynchronous byte stream, but the protocol does not give specific values ​​for processing data traffic. In the early days, small-scale hardware circuits were used, and the shift XOR tap method was used. The circuit implementation was relatively simple, and the synchronous bit stream method was used; later, the software was implemented, and the synchronous bit stream method was also used. The programming was relatively simple, but the largest The disadvantage is that the single-channel data flow is low. And some field programmable gate array chip manu...
