网络结构自调整的柔性内涵初探

从微观和定量意义的服务效果对应用要求一致匹配的角度探索了网络重构柔性的内涵,具体地揭示了跟随应用时变要求的时变信道这一可重构网络的核心特征,然后从该时变信道"一致满足"应用要求的目标出发,进一步揭示了重构柔性的"渐变跟随"、"着眼整体"、"隐性隔离"和"自主驱动"4个重要内涵,采用指数移动平均、n:m表决、马尔科夫决策和强化学习定量地刻画了效果对要求的稳定偏离和资源调整幅度的最佳顺序决策。

Preliminary study on the connotation of flexibility in dynamically reconfigurable networks

From the microscopic and quantitative viewpoints,the connotation of the structural flexibility of reconfigur-able networks was explored.More accurately,a key feature,i.e.,the dynamic data channel varying with service demands,of reconfigurable networks was first exhibited and explained.Four dominant implications of the flexibility were then re-vealed as gradually mapping to demands,keeping global performance good,implicit isolation,and self-driven control.Finally,related quantitative models and methods for both determining the stable deviation of outcomes from demands and computing the volume of resource dynamically reconfigured were investigated by using the exponentially moving aver-age,the n:m voting scheme,Markov decision processes(MDP) and reinforcement learning,respectively.
