Embodiment

[0112] In the air-space-ground integrated information network, define the underlying network G s ={Node s ,Link s } where Node={ID, Type, NodeProperties}, Link={Ori, des, LinkProperties}. virtual network G v ={Node v ,Link v }, then the user virtual network request at time t is VNR i ={t, M, Node, Link}, t=1...I,

[0113] Drawing on the application scenarios of traditional terrestrial networks, and considering the time-varying and heterogeneity characteristics of the integrated air-space-ground information network, the underlying physical resources of the integrated heterogeneous network are abstracted into a logical resource pool LogicalPool.

[0114] Define the virtual network request in a certain time slice to apply for a resource vector to the logical resource pool as:

[0115] LogicalPool(VNR(n i ))=[SensorRes, BandWidthRes, FreqRes, CalcRes, EngyRes, StorageRes, OthRes] (12) with figure 2 Based on the vector distribution diagram of business resources, sensor re...

Abstract

The invention discloses a virtual network mapping method, device, equipment and storage medium based on the space-space-ground integrated information network. The present invention abstracts the multi-dimensional physical network resources of the space-space-ground integrated heterogeneous fusion network, and uses integer linear programming as The research tool combines the minimization of energy consumption and cost as the overall optimization goal. With the help of the proposed resource cube classification model, the user's virtual network request service tendency is judged, and the personalized mapping strategy is adopted to complete the virtual network mapping, aiming to improve the basic implementation provider ( InP) virtual network mapping benefits, while reducing mapping energy consumption and saving mapping costs, to achieve a reasonable use of resources.

Description

【Technical field】 [0001] The invention belongs to the field of air-space-ground integrated information network virtualization, and in particular relates to a virtual network mapping method, device, equipment and storage medium based on an air-space-ground integrated information network. 【Background technique】 [0002] Due to the explosive growth of traditional terrestrial network communication users and service types, future networks need to flexibly provide more network underlying physical resources to meet emerging network application requirements with different service quality requirements. At the same time, satellite communications ushered in a new round of development boom in the world, and the fifth generation of terrestrial mobile communications (5G) entered commercial use. Using modern information network technology, the fusion of satellite networks, 5G ground networks, and other air-space-ground integrated networks (SAGIN) has become a new hot spot in academic and c...
