Problems solved by technology

[0010] In the actual network environment, the transmission data is constantly changing. The multiplexing of PPPMUX frames is constrained by a fixed time and packet length. Various changes that will occur during actual transmission are not considered, which will often affect the multiplexing. efficiency, which in turn affects the transmission efficiency

Embodiment 3

[0100] image 3 The flow chart of Embodiment 3 of the data transmission method provided by the embodiment of the present invention includes:

[0101] 301. Obtain the length of the PPPMUX subframe header;

[0102] When the two ends of the PPP system negotiate the structure of the message, the two parties send the format information they support to the other end, and finally obtain the format standard supported by them, and the length of the PPPMUX subframe header is usually confirmed and obtained according to the negotiation result.

[0103] 302. According to the length of the PPPMUX subframe header, determine whether the effective information ratio after multiplexing is smaller than the effective information ratio before multiplexing; if yes, execute step 303, otherwise execute step 304;

[0104] Assuming that the message payload length is L, the number of PPP subframes multiplexed in a PPPMUX subframe is N, the length of the PPPMUX subframe header is M, and the length of the...

Abstract

The embodiment of the present invention discloses a data transferring method and a data processing apparatus. Wherein, one method comprises that acquiring transferred data; adjusting multiplexing parameters according to the transferred data; utilizing the multiplexing parameters to multiplex the sent data to acquire a point-to-point multiplexing protocol frame; and sending the point-to-point multiplexing protocol frame. Another method comprises that acquiring the head length of a point-to-point multiplexing protocol sub-frame; according to the point-to-point multiplexing protocol sub-frame, judging whether the proportion of significant bit after multiplexing is smaller than the proportion of significant bit before multiplexing; if the proportion of significant bit after multiplexing is smaller than the proportion of significant bit before multiplexing, sending a point-to-point protocol sub-frame; if the proportion of significant bit after multiplexing is larger than the proportion of significant bit before multiplexing, sending a point-to-point multiplexing protocol frame. The embodiment of the present invention can effectively improve transferring efficiency.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data transmission method and a data processing device. Background technique [0002] Point-to-Point Protocol (PPP, Point-to-Point Protocol) is a link layer protocol designed for simple links such as transmitting data packets between equivalent units. This link provides full-duplex operation and delivers packets in order. The design purpose is mainly to establish a point-to-point connection to send data through dial-up or leased line, making it a common solution for simple connection between various hosts, bridges and routers. [0003] The PPP multiplexing protocol (PPPMUX, PPP Multiplexing) is a protocol used for frame multiplexing in the PPP protocol cluster. It allows multiple common PPP frames to be multiplexed and encapsulated into one PPPMUX frame, thereby reducing the header consumption of PPP frames and improving bandwidth utilization. [0004] The PPPMUX frame...
