Embodiment 1

[0058] This embodiment provides a message forwarding method, which selects the air interface according to the delay of the air interface for establishing communication with the satellite, and implements load sharing among multiple air interfaces through the change of the delay of the air interface. In this way, it can better adapt to the scenario where the bandwidth and delay of the air-ground link are constantly changing.

[0059] Specifically, the method can be performed by a ground station in communication with the satellite, Figure 4 A schematic flowchart of a message forwarding method provided by an embodiment of the present application, in this method, each step can be performed by different modules of the ground station antenna, and the ground station antenna includes a plurality of Ethernet ports for communicating with The ground router communicates, and also includes multiple air interfaces (referred to as air interfaces) for communicating with satellites, and also i...

Embodiment 2

[0084] Based on the load sharing in the HASH mode, there will be a small amount of disorder when the path selected by the traffic link is triggered at the moment when the HASH factor is adjusted, which will affect the service system.

[0085] In the manner of using the first embodiment, this embodiment provides a packet forwarding method by estimating the remaining time for the last packet to reach the peer end, so as to select the air interface with the smallest delay and the delay greater than the remaining time, and go to Avoid out-of-order problems caused by packets sent first.

[0086] specific, Figure 7 A schematic flowchart of the packet forwarding method provided in this embodiment is shown, as shown in Figure 7 As shown, the method includes:

[0087] Step 701, periodically polling the Ethernet port of the network device.

[0088] Step 703: If it is found that at least one complete to-be-scheduled packet is received in the receive queue corresponding to the Ethern...

Embodiment 3

[0099] On the basis of the above two embodiments, this embodiment also provides a packet forwarding method, Figure 8 A schematic flowchart of a packet forwarding method provided in this embodiment is shown, and the method includes:

[0100] Step 801, periodically polling the Ethernet port of the network device;

[0101] Step 803: If it is found that at least one complete to-be-scheduled packet is received in the receive queue corresponding to the Ethernet port, the delay of each air interface is acquired.

[0102] The implementation process of step 801 and step 803 is similar to that of step 101 and step 103 in the first embodiment, and is not repeated in this embodiment.

[0103] Step 8041, the air interface obtains the number of tokens in the token bucket corresponding to itself, wherein the number of tokens placed in the token bucket is determined according to the current bandwidth of the link corresponding to the air interface.

[0104] The arbitration module can send s...

Abstract

This manual provides a message forwarding method and device. The method includes: periodically polling the Ethernet port of the network device; if it is found that at least one complete message to be scheduled is received in the receiving queue corresponding to the Ethernet port , the time delay of each air interface is obtained; and the air interface meeting the time delay condition is determined according to the time delay of the air interface to forward the message to be scheduled. The method provided by the present application selects an air interface through the time delay of the air interface for establishing communication with the satellite, and implements load sharing among multiple air interfaces through the time delay change of the air interface. In this way, it can better adapt to the scenario where the bandwidth and delay of the air-ground link are constantly changing.

Description

technical field [0001] This specification relates to the field of communication technologies, and in particular, to a method and device for forwarding a message. Background technique [0002] With the gradual deployment of the fifth-generation 5G communication technology, the development of bearer services has been promoted. While the bandwidth has been doubled, the coverage of wireless base stations, which are the main force of ground communication, is getting smaller and smaller, and the deployment density of base stations is getting higher and higher. , Under the premise of fierce competition among operators, it is obviously impossible to develop 5G first in some remote areas with large-scale and full coverage. This has resulted in isolated islands that cannot be covered in some remote areas (such as forests, deserts, oceans, etc.) and sparsely populated areas. The sixth generation of 6G communication technology has begun to explore and develop, in order to achieve the o...
