QoS guarantee system of 5G satellite convergence network

Abstract

A QoS guarantee system of a 5G satellite convergence network comprises a resource cache and flow control module, and is characterized in that services in the network are classified, and data flows ofdifferent services are separated; a network monitoring module can set a probe at a network entrance of the 5G satellite convergence network, the probe is used for monitoring network flow of differentservices to obtain network delay, jitter and packet loss rates of the different services, and the network delay, jitter and packet loss rates are sent to the evaluation and decision module; the evaluation and decision module is used for obtaining an MOS score of QoS according to the network delay, jitter and packet loss rates of different services, and determining a network adjustment strategy anda network adjustment strategy according to the MOS score by utilizing a pre-stored corresponding relationship between the MOS score and the network adjustment strategy, including processing of data packets in the network, routing decision and network configuration; and the network control module is used for adjusting and controlling the network according to the network adjustment strategy. According to the invention, non-blocking stable communication capability is realized, and diversified application services are provided.

Description

technical field [0001] The invention relates to a QoS guarantee system for a 5G satellite fusion network, belonging to the technical field of 5G satellite fusion networks. Background technique [0002] The 5G satellite fusion system is formed by the interconnection and integration of various heterogeneous networks. Its node types, terminal types, interface types, and protocol types are complex and diverse, and the satellite nodes are always in high-speed operation. At the same time, most of the existing interconnection architectures use specific protocols. The network interconnection mode, its internal topology, and port bandwidth allocation methods are all fixed, and the hardware-solidified rigid interconnection architecture puts forward new requirements for heterogeneous network integration.

AI Technical Summary

Problems solved by technology

Mainly manifested in: First, non-blocking and stable connectivity, providing diversified application services, requiring 5G satellite fusion network to achieve full coverage of network interconnection and stable connectivity; second, heterogeneous network fusion interconnection capabilities, the network involved in 5G satellite fusion system The types are heterogeneous and diverse, especially the satellite network and the terrestrial 5G network operating environment are quite different, and the network connection presents the characteristics of discontinuous connectivity and large delay variance. Network interconnection needs to integrate different rate channel bandwidths, different magnitudes of transmission delay, Intermittent link connectivity and the impact of link dynamic switching; the third is flexible adaptability. The existing rigid interconnection architecture causes inflexibility in system networking and inconvenient expansion. Therefore, flexible adaptability is required to achieve Flexible system expansion, open support for new protocols, and online optimization and expansion of system operation
