Service quality quaranterring method, system, broadband access terminal and network device

Abstract

Being setup in broadband access terminal, cipher key is in use for establishing credible session. Using the cipher key, the broadband access terminal builds PPPOE session to office end. Through the credible PPPOE session, the broadband access terminal transfers marked traffic stream to office end. Based on prearranged strategy of QoS, the office end carries out operation of process QoS for traffic stream transferred from credible PPPOE session. The invention guarantees that stream marker of data message transferred to office end by the broadband access terminal is a legal stream marker, and prevents office end from baleful cheating through QoS from user side so as to make office end ensure providing QoS in high priority. Thus, the invention guarantees lawful rights and interests of users' terminals finally.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for guaranteeing service quality, a broadband access terminal and network equipment located at the central office. Background technique [0002] With the development of communication networks, there are more and more network terminals and more and more services. In the case of limited resources such as network bandwidth and network equipment processing capabilities, it is necessary to provide differentiated services for different business flows, so as to provide different quality of service (QoS) for different business flows, such as guaranteeing resources for high-priority services, giving priority to High-priority business processing and so on. [0003] The guarantee of service quality is aimed at end-to-end, and any problem in any link on the end-to-end link will affect the service quality. Currently, the QoS processing model includes: flow ...

AI Technical Summary

Problems solved by technology

[0008] The main disadvantage of method 2 is: any gateway can transmit the data message to the central office, and the central office cannot control the QOS marking of the data message by the gateway, that is, any user terminal can give priority to the QOS of any service flow Therefore, the second method also cannot guarantee that the flow label of the service flow transmitted to the central office is a legal flow label, so that the central office cannot correctly provide service quality assurance for the service flow
