Embodiment 1

[0034] Embodiment 1 of the present invention provides a data transmission method, including: after determining that the first interface is the bottleneck of the user data transmission channel, reducing the rate limit or resource limit of the second interface; wherein the second interface is used to transmit the second node Using the user data received by the first interface; scheduling and sending the user data according to the reduced rate limit or resource limit of the second interface.

[0035] Wherein, the limit rate of the second interface is the maximum rate allowed by the second interface to send data, that is, the rate at which the second interface sends data does not exceed the limit rate of the second interface, and the limit rate of the second interface can be a variable ; The limited resource of the second interface is the maximum value of available resources allowed by the second interface to send data, that is, the resources occupied by the second interface to sen...

Abstract

The embodiment of the invention provides a data transmission method, a network node, and a network system, where the data transmission method comprises reducing speed limit or resource limit of a second interface after determining that a first interface is a bottleneck of a user data transmission channel; said second interface is used for transmitting user data of a second node received via the first interface; scheduling user data and transmitting the same according to the reduced speed limit or resource limit of the second interface. With the technical plan provided in the embodiment of the invention, the second interface is used as the bottleneck so as to solve the problem of user fairness under bandwidth limited situation of the first interface.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method, a network node and a network system. Background technique [0002] At present, the proportion of voice services in the communication system is getting smaller and smaller, and the proportion of data services is increasing. Therefore, the bandwidth requirements provided by the communication system are also getting higher and higher. Currently, the services delivered in the communication system are mainly divided into two categories: real-time services and non-real-time services. In the existing communication system, priority services are generally provided, and real-time services are set with a higher priority, so that real-time services are sent preferentially, avoiding packet loss and data caching in real-time services, so that the quality of real-time services is guaranteed . For non-real-time services, it is usually necessary to allocate ban...
