Embodiment Construction

[0038] 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:

[0039] figure 1 It is a multi-channel system diagram of framing in the present invention, which is used to illustrate the connection relationship of each channel of framing. For each channel, the direction of data flow is to enter the channel scheduling processor first, then the data is sent to the data buffer 1, and then the data is sent The processor sends the data into the data buffer 2 after processing, and then outputs the data to the channel scheduling processor.

[0040] figure 2 It is a single-channel framing data processing flow chart of the present invention, illustrating a data processing flow when converting a PPP (point-to-point, the same below) packet into an advanced link control procedure data packet in a single channel, including character escape and fast frame correctio...

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 ofdata 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] Protocol RFC1662 (PPP in HDLC-like framing) proposes an advanced link control procedure 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...
