Example Embodiment

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] The embodiment of the present invention adopts a message processing method that considers the multi-link protocol (MP) group under various conditions, so as to realize that the MP group can be normally started under various conditions and the packet grouping work is completed. Method, and provides an automatic reset function.

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...
