Embodiment Construction

[0053] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0054] see figure 1 , figure 1 It is an overall structural diagram of a QoS strategy scheme for heterogeneous networks in the example of the present invention.

[0055] figure 1 The left side is a schematic diagram of a general QoS framework. This model summarizes the QoS information of each layer to form network status information. The network status information is stored by each layer and can be accessed separately to read the required network status information. . When there is a QoS requirement, the application layer can compress or package data according to the network status and the urgency of business needs; the transport layer can perform macro-control according to the current network status, such as realizin...

Abstract

The invention provides a method and a system for realizing a heterogeneous network QoS policy, which are mainly embodied in the following three aspects: In the aspect of Qos module, Qos-RN architecture, suitable for the combination of multiple means of communication, is provided. In the aspect of QoS mapping, a QoS mapping method based on three-dimensional model is proposed, and a mapping feedbackmechanism is added. In the aspect of QoS routing, an improved OSPF algorithm is proposed by adding QoS requirements to the OSPF algorithm. Simulation verification on OPNET platform shows that the heterogeneous QoS policy ensures service meets the QoS constraint, reduces service delay, improves resource utilization, reserves bandwidth channel and makes full use of bandwidth resources when there ishigh priority service demand.

Description

technical field [0001] The present invention relates to the field of heterogeneous networks, more specifically, to a method and system for realizing QoS policies of heterogeneous networks. Background technique [0002] Heterogeneous network is the product of the coexistence of multiple communication methods caused by people's increasing communication and network requirements. It is composed of different types of communication equipment, network equipment and systems, which can combine different network protocols and support different functions and applications. network of. The heterogeneity, integration, and variability of heterogeneous networks can solve the problems of single communication means with single structure and difficult to guarantee effectiveness in harsh environments, but it will lead to unreasonable planning of communication resources, chaotic access, difficulty in guaranteeing priority services, and security issues, etc. Aiming at the problems of unreasonab...
