Data packet transmission method and transmission device
First Claim
1. A data packet transmission method, wherein the method comprises:
- acquiring, by a front end node, multiple sub data packets obtained by division;
performing, by the front end node, inter-packet combination encoding on the multiple sub data packets, and obtaining multiple encoded sub data packet groups, wherein one of the encoded sub data packet groups comprises at least one encoded sub data packet; and
sending, by the front end node, the multiple encoded sub data packet groups to a destination node separately through at least two transmission paths.

Abstract
The present invention discloses a method. In a process of splitting and sending a data packet, after dividing a data packet to be sent to a destination node into multiple sub data packets, a front end node performs inter-packet combination encoding on the sub data packets in a combination encoding mode, and sends obtained encoded sub data packet groups to the destination node. Even if a channel state of a transmission path suddenly deteriorates, because the destination node does not need to wait to receive all encoded sub data packet groups provided that an original data packet can be parsed out by combining content in a received encoded sub data packet group and a corresponding decoding mode, a process in which the destination node receives the data packet is less affected by a sudden network case, and transmission efficiency is not significantly affected.
