Embodiment Construction

[0029]The mobile agent-based satellite network service quality assurance method of the present invention is composed of four parts: service quality mapping, resource reservation, satellite network monitoring and resource reservation negotiation. Through the mapping of quality of service, the user's business requirements are converted into QoS parameters such as bandwidth, delay, delay jitter, and packet loss rate that the network layer can recognize, and corresponding bandwidth resources are allocated for the QoS path through resource reservation. Monitoring to determine whether the satellite link is switched or whether the satellite node and the link fail, so that the reserved resources are updated, and more QoS requests are satisfied through the negotiation of resource reservation. The quality of service guarantee method of the present invention is described as follows:

[0030] 1) The user sends a QoS request, and the receiving satellite converts the request into QoS parame...

Abstract

The invention provides a method for ensuring satellite network service quality based on a mobile agent which is used for solving service quality ensuring problem of various QoS operation in the satellite network transmitting from end to end. The method makes the satellite network no needing special resource reservation signaling agreement, but distributing a bandwidth resource needed by QoS route through the agreement of the mobile agent, reacts to linkage switch, linkage invalidation or node invalidation allodially and dynamically by using changes of the mobile agent monitor satellite network, keeping accuracy of the resource reservation information, and satisfying more QoS requirements by using the mobile agent for realizing agreement of the resource reservation. The method can process network resource reservation according with operation QoS requirement before sending the data, provide QoS ensuring from end to end and process cooperation with the resource reservation.

Description

technical field [0001] The invention is a mobile agent-based satellite network service quality assurance method. It is mainly used to solve the end-to-end service quality assurance problem of various QoS (Quality of Service) services in satellite network transmission, and belongs to the field of satellite network communication technology. Background technique [0002] With the ever-increasing demand for interactive real-time multimedia services and mobility, the satellite network will surely become an important part of the global mobile communication system. Global seamless coverage, mobility, no geographical restrictions and providing QoS guarantees have become global mobile important characteristics of the system. The satellite network QoS technology faces special challenges due to special factors such as the dynamically changing topology of the satellite network, limited on-board processing capacity, and background noise in space. [0003] Intelligent agents, especially...
