Method and apparatus for processing message of MP group

Abstract

The embodiment of the invention relates to a message processing method applied to a multi-link protocol (MP) group and a device thereof. The message processing method applied to the multi-link protocol (MP) group comprises the following steps: whether a first fragment message received is the initial fragment message or not is judged; if not, the first fragment message is stored and subsequent fragment messages are received; and when the fragment message received is the initial fragment message and the initial fragment message is confirmed to be the initial fragment message required by the entry of packet working state, the entry of packet working state is realized according to the initial fragment message. Under the condition that the initial fragment message is received a little late due to the link time delay of the first message after the MP group is started, the method can prevent the whole message from losing, perfect the normal start process of the MP group and increase the accuracy of the MP group packet.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a message processing method and device applied to the MP group. Background technique [0002] The Point-to-Point Protocol (PPP) has produced an extended feature Multilink Protocol (MP) in use. Its principle is to bundle multiple physically independent PPP links to external Expressed as a logical link, these physical channels are called an MP group. The data packet transmitted on the MP group will be fragmented first. The B flag in the head fragment is set to 1, and the E flag in the tail fragment is set to 1. All fragmented packets in the same MP group will follow Increment the sequence number, and then send the fragments to each sub-link for transmission according to the sequence number. In an MP group, since the actual delays of different bound links may be different, the fragments sent sequentially by sequence number will pass through the delay of different links, an...

AI Technical Summary

Problems solved by technology

[0004] The prior art described above has at least the following disadvantages: when the header fragment of the data packet where the first fragment is located is only delayed by a small time than the first fragment and arrives at the receiving end due to the delay in the link , since the sequence number of the header fragment is smaller than the initial comparison value, the header fragment can only be discarded, so that the first data packet cannot be assembled, thus affecting the correct rate of MP packet assembly
