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 present invention provides a heterogeneous network QoS policy implementation method and system, which are mainly embodied in the following three aspects: In terms of QoS model, a QoS-RN architecture is proposed, which is suitable for the combination of various communication means. In terms of QoS mapping, a three-dimensional model-based QoS mapping method is proposed, and a mapping feedback mechanism is added at the same time. In terms of QoS routing, a QoS requirement is added on the basis of OSPF algorithm, and an improved OSPF algorithm is proposed. Through the simulation verification of the QoS policy scheme on the OPNET platform, it is shown that the QoS policy of the heterogeneous network ensures that the business meets the QoS constraints, can reduce business delays, improve resource utilization, and when there are high-priority business needs, it can Reserve bandwidth channels to make full use of bandwidth resources.

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...
