Embodiment

[0040] figure 1 A schematic diagram of a network topology for implementing this embodiment is given. On the LAN side, the end user 1 is connected to the cascading gateway through an ultrashort wave link; on the WAN side, the cascading engine is connected to the core network through a mobile network, a short-wave network and a satellite network. A virtual reconstruction server and end users 2 are deployed in the core network. Among them, the virtual reconstruction server is used to integrate and restore the data from multiple links, and then send it to the end user 2 .

[0041] Based on the above environment, the specific process of dynamically adjusting the QoS priority of the LAN side and the WAN side to realize the closed-loop mutual coupling of QoS is as follows:

[0042] When LAN user 1 sends data to WAN user 2:

[0043] The user 1 control plane entity unit adds data to the QoS queue of the data plane according to the QoS priority of the service;

[0044] User 1's QoS ...

Abstract

The invention provides a heterogeneous cascade network QoS closed-loop mutual coupling system and method. The system comprises a LAN QoS control module, a WAN QoS control module and a cascade engine, the LAN QoS control module, the WAN QoS control module and the cascade engine respectively comprise a control plane entity unit and a data plane entity unit, and the control plane entity units of the LAN QoS control module, the WAN QoS control module and the cascade engine respectively comprise a user attribute memorizer SPR module, a P-CSCF module, a PDF module and a PEP module; the data plane entity units of the LAN QoS control module, the WAN QoS control module and the cascade engine respectively comprise a QoS queue module and a channel queue module. With the system and method, the QoS priority on the LAN side and the WAN side can be dynamically regulated, QoS closed-loop mutual coupling is achieved, the QoS of a cascade network is guaranteed, the QoS is improved, and the utilization rate of resources is guaranteed at the same time.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a heterogeneous cascade network QoS closed-loop mutual coupling system and method. Background technique [0002] Service quality assurance technology is one of the core technologies of the new generation network. Quality of service is an overall measurement of the services provided by the distributed system based on certain key parameters. Specifically, it refers to the degree to which the distributed system meets a series of service requirements of the upper application during the service process. These requirements are often quantified as QoS Indicators, such as performance indicators such as transmission delay, delay jitter, bandwidth requirements, loss rate, and throughput. The effectiveness of applications (such as real-time, multimedia, etc.) in some distributed network environments depends on whether the system can provide certain quality of service guar...
