多域网络中基于域间时延博弈的端到端动态协同切片方法
End-to-end dynamic collaborative slicing method based on inter-domain delay game in multi-domain network
摘要
Abstract
Aiming at the problem of uneven inter-domain delay in slicing in multi-domain networks,this paper proposed an end-to-end dynamic cooperative slicing method based on inter-domain delay game.This method used game theory methods to allocate end-to-end delay constraints to different network domains,and deployed slices within the domain to obtain correspon-ding game benefits.It used the DDPG algorithm to continuously update the game strategy,and finally obtained the optimal de-lay allocation ratio and slice deployment solution.Experiments show that compared with the traditional static allocation algo-rithm,the proposed algorithm has obvious advantages.Compared with the empirically iterative DSDP method and the DQN-SNAF algorithm,the IDGA algorithm increased the slice deployment success rate by about 8％and 3％respectively under 100 slice requests.At the same time,the node resource utilization rate increased by about 5.75％and 1.96％.There are also sig-nificant advantages in reducing deployment costs.关键词
