Method and system for realizing terminal quality of service of internet voice transmission system

Abstract

The invention discloses a method and a system for realizing the terminal quality of service of an internet voice transmission system. The quality of service link of the system comprises a quality of service control module and a quality of service execution module. The method comprises the following steps that: a user configures parameters and then a CGI module writes the parameters into a configuration file; the quality of service control module generates the configuration file into a flow control script for execution and then writes a quality of service policy into an inner core of the system; and when the inner core of the system receives a data packet, the quality of service execution module configures the data packet. A first-in first-out policy comprising the determined priority and allocated bandwidth is introduced to configure the QoS quality of service, and end-to-end quality of service in an internet voice transmission application system is uniformed, a superior QoS processing mechanism is ensured on a VoIP terminal, the voice quality of the terminal is guaranteed, real-time smoothness of IP phones is realized and the basic requirements of the user are met; and the low cost is realized and the system is easy to develop and maintain.

Description

technical field [0001] The invention relates to the field of QoS quality service of a VoIP Internet voice transmission system, in particular to a method and system for realizing terminal quality service of the Internet voice transmission system. Background technique [0002] VoIP (Voice over Internet Protocol, hereinafter referred to as VoIP) is an IP-based voice transmission, which refers to the transmission of voice over an IP network. Generally speaking, it is Internet telephony, Internet telephony, or IP telephony for short. For a long time, one of the key problems that has not been solved well in the existing IP telephony technology is the quality of service (QoS, hereinafter referred to as QoS) problem of its business. [0003] Since the IP phone needs to rely on the IP network as the basic data transmission network, most of the current IP networks cannot provide effective QoS quality services, so the QoS quality service problem of the IP network has become one of the ...

AI Technical Summary

Problems solved by technology

[0005] However, the technical support of QoS quality service has not been unified in the VoIP Internet voice transmission application system; therefore, generally speaking, there is still no end-to-end QoS quality service technology based on the SIP session initiation protocol; and currently The network is gradually moving in the direction of all-IP. In order to realize telephone and other carrier-class services in the all-IP network, the application of VoIP Internet voice transmission system is more closely related to QoS quality service, which has very high requirements for QoS quality service; One of the most lacking technologies for VoIP Internet voice transmission applications is end-to-end QoS quality of service control. How to provide basic or even good QoS quality of service control is not only a problem that must be solved on the evolution road of NGN (Next Generation Network) The problem is also the problem that must be solved on the terminal
