Method for guaranteeing message transmission and network node

Abstract

This invention discloses one method to protect message transmission and one network joint, which comprises the following steps: network point monitors low speed linkage wide band changes; if yes, then adjusting wide band process and adjusting high speed network low speed network message transmission according to adjust wide band; then sending message to low speed network. This invention ensures message transmission to improve business service quality into the range of low speed linkage wide load.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method for ensuring message transmission and a network node. Background technique [0002] With the development of network technology, different types of network interconnections have become a reality. figure 1 It is a schematic diagram of connecting a high-speed network through a low-speed network. see figure 1 , in many occasions at present, it is necessary to connect high-speed networks with higher packet transmission rates through low-speed networks with lower packet transmission rates. For example, in order to save the transmission bandwidth of the intermediate network, different Ethernet high-speed networks such as local area networks or metropolitan area networks can be connected together through low-speed networks such as wireless networks or satellite networks. [0003] see figure 1 , when a high-speed network is connected through a low-speed network, because the...

Problems solved by technology

However, in actual service implementation, the available bandwidth of links in low-speed networks cannot always meet its bandwidth configuration. Under the influence of many factors, the available bandwidth of links in low-speed networks will decrease

For example, due to environmental factors such as weather, distance, and relative speed, or due to link switching in low-speed networks, the available bandwidth of links in low-speed networks will be greatly reduced

However, in the prior art, the gateway does not consider the actual bandwidth changes in the low-speed network at all, and always adjusts the rate of the message according to a fixed bandwidth reference value. In this way, when the link bandwidth in the low-speed network decreases, It will cause the flow of packets entering the low-speed network to be larger than the range that the link bandwidth of the low-speed network can actually carry, resulting in congestion on the low-speed network, and delays or even loss of packets in the low-speed network, so it cannot fundamentally Guaranteed message transmission, greatly reducing business service quality

[0006] In addition, after the available bandwidth of the link in the low-speed network decreases, the available bandwidth of the link in the low-speed network will recover, that is to say, the available bandwidth will increase, but in the prior art, the increase in bandwidth in the low-speed network is not considered time bandwidth processing

[0007] It can be seen that in the existing technology, the gateway does not consider the actual bandwidth changes in the low-speed network, but blindly adjusts the packet rate according to a fixed reference value, which cannot adapt to the change in the carrying capacity caused by the bandwidth change in the low-speed network in a timely manner. , so the transmission of the message cannot be fundamentally guaranteed, which greatly reduces the service quality of the business
