Problems solved by technology

This method reduces the number of packet loss to a certain extent, but because the source node caches and forwards the data packet, it increases the switching delay time

Embodiment Construction

[0028] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] One of the core concepts of the embodiments of the present invention is that, when the mobile node is handed over from the source node to the destination node, the second node receives a data packet sent from the first node to the mobile node, wherein the data packet is the first When a node detects that sending the data packet to the mobile node fails, it is sent to the second node, the first node is the source node or the first node receives the data packet from the source node The data packet; the second node sends the data packet to the mobile node; if the second node detects that sending the data packet to the mobile node fails, then sends the data to a third node packet, so that the third node sends the data packet to...

Abstract

The embodiment of the invention provides a data package forwarding method and device. The method includes the steps that when a mobile node is switched to a destination node from a source node, a second node receives a data package which is from a first node and is sent to the mobile node, the data package is sent to the second node under the condition that the first node detects that the data package cannot be successfully sent to the mobile node, and the first node is used as the source node or the first node receives the data package from the source node; the second node sends the data package to the mobile node; if the second node detects that the data package cannot be successfully sent to the mobile node, the data package is sent to a third node, and accordingly the third node can send the data package to the mobile node. By means of the data package forwarding method and device, the forwarding time of the data package is shortened.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data packet forwarding method and device. Background technique [0002] In the prior art, some nodes can be moved, for example, mobile terminals such as mobile phones can be moved. Handover occurs when these mobile nodes move from the coverage area of ​​one node to the coverage area of ​​another node. [0003] At present, a relatively common switching method is hard switching, which is also called a non-forwarding method of data packets. In this method, when the mobile node moves from the current node to another node, if the signal received from the current node is relatively weak and the signal received from the destination node is relatively strong, the mobile node will immediately disconnect from the source node. Node connection, and establish a connection with the destination node. When the mobile node switches to the destination node, it stops receiving data from ...
