【摘要】：在不斷衍化的互聯(lián)網(wǎng)環(huán)境下,云服務呈現(xiàn)出異構分散,動態(tài)多變,數(shù)據(jù)規(guī)模龐大等特征,結合具有自主決策能力的多agent系統(tǒng)(MAS)來實現(xiàn)云服務的分配和管理近年來逐漸成為研究熱點。為追蹤整體效用隨時間的衰減趨勢從而進一步優(yōu)化協(xié)同策略,在云服務Saa S層基礎上,提出基于時間邊際效益的協(xié)同框架——Que Ty。該框架為云服務的broker(代理)、provider(提供商)和executor(服務執(zhí)行者)之間引入時間邊際效益概念,并在此基礎上提出通信衰減算法和選播算法,實現(xiàn)了對服務流程的控制,并進一步平衡了整體效用,降低了通信損耗。
[Abstract]:In the constantly evolving Internet environment, cloud services show the characteristics of heterogeneous, dynamic, dynamic, large data scale, and so on. In recent years, it has become a hot topic to realize cloud service allocation and management by combining multi-#en0# system with autonomous decision ability. In order to track the decreasing trend of overall utility over time, the cooperative strategy can be further optimized. On the basis of cloud service Saa S layer, this paper proposes a collaborative framework based on temporal marginal benefit, named que Ty.The framework introduces the concept of time marginal benefit between broker (broker) and executor (service executor) of cloud service. On this basis, the communication attenuation algorithm and the anycast algorithm are proposed to control the service flow, and the overall utility is further balanced, and the communication loss is reduced.
