Embodiment Construction

[0069] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0070] The key idea of ​​the present invention is to introduce a QoS policy conversion device into the original bearer network, and through methods such as code flow convergence, the nodes (such as routers) of the original bearer network can adopt simple strategies such as physical ports and IP quintuple matching. Flow classification, and these flow classification methods can be supported by the bearer network itself. The corresponding OSI seven-layer model can be described as follows: QoS policy conversion equipment converts high-level flow classification requirements (such as application layer service differentiation) into low-level flow classification basis (such as IP quintuple), so that bearer network devices (such as routers) It can perform traffic classification at a lower level to meet the high-level traffic classification require...

Abstract

This invention relates to a conversion device for service quality strategy including: a network interface module providing the interface to outside and processing related protocol of carrying network,a signaling process module processing signaling of applied service, responsible for setting up and releasing of conversation and providing service information necessary for the management module, a managing module carrying out service identification and user certification and controlling forward of code streams, a code stream forward module forwarding code streams based on the forward list createdby the signaling process module. The method includes: setting a strategy conversion device n corresponding to the needs of service n to analyze n to the device n to verify its authority to finish con tinuation of the service based on its list identification.

Description

technical field [0001] The present invention relates to the communication field, in particular to a quality of service (service quality) (QoS Quality of Service) policy conversion device and method. technical background [0002] Along with the growth of various broadband services, there is an increasing demand for the quality of service (QoSQuality of Service) of the Internet. Although existing network devices support the implementation of QoS policies through technologies such as DiffServ Differentiated Services and MPLS Multi Protocol Label Switching, they mainly use five-tuples (source address, source port, destination address, etc.) , destination port, protocol type) or physical ports to distinguish services, and generally can only be pre-configured, which is difficult to meet the requirements in practical applications. What is needed in practical applications is a QoS technology that can differentiate services based on "service type + user". [0003] To this end, the ...
