Problems solved by technology

However, in the face of symmetrical or uplink-oriented businesses, the demand cannot be met
Due to the complex types of equipment in the access network, the huge number, and the complex problems
Therefore, it is difficult to fully deploy the uplink QoS mechanism point by point from the source in the access network

Embodiment Construction

[0029] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation of the present invention.

[0030]Since the multi-service access gateway MSE (Multi-Service Edge) is at the end of the access network, it is generally believed that the data is congested before reaching the MSE, so the MSE cannot provide QoS guarantee for the upstream service flow. However, in fact, the sending of data packets is instantaneous, and there is a time course for data traffic to increase from small to large. That is, before access congestion occurs, MSE can monitor related business traffic and its changes. When the present invention finds that there is a tendency of congestion in a certain place, it starts to reduce the low-prior...

Abstract

The invention discloses a method for realizing uplink QoS (Quality of Service) based on an IP access network and a multi-service access gateway. The method comprises the following steps: the multi-service access gateway judges whether the uplink flow flowing through each link node exceeds the uplink early-warning threshold of each link node according to the uplink early-warning threshold of multiple link nodes on the uplink from a client to the multi-service access gateway; and the multi-service access gateway reduces the flow of the uplink low priority service so as to ensure the QoS of the uplink high priority service flow at the client if the uplink flow of any one link node flowing through multiple link nodes exceeds the uplink early-warning threshold of any one link node. The invention can effectively prevent congestion of the uplink and satisfy the quality of service of the uplink flow of the high priority service at lower reformation and cost.

Description

technical field [0001] The present invention relates to the field of integrated service network of the Internet, and more specifically, relates to a method and a multi-service access gateway for realizing uplink quality of service (Quality of Service, QoS) based on an IP access network. Background technique [0002] With the development and popularization of the Internet, the development trend of the Internet as a future converged network is becoming more and more obvious. Multimedia communications such as voice and video and other key Internet application services such as video surveillance will be carried by the Internet in a unified manner. This will change the traditional Internet network's best-effort transmission mode, and implement dynamic end-to-end for the so-called key business flows that need to be guaranteed. Terminal business bandwidth and quality assurance. For key services that must be guaranteed, such as multimedia communication and video surveillance, it is...
