【摘要】：隨著網(wǎng)絡(luò)服務(wù)的蓬勃發(fā)展,服務(wù)選擇方法成為重要的研究熱點。而隨著云數(shù)據(jù)中心的發(fā)展,大量網(wǎng)絡(luò)服務(wù)部署在云數(shù)據(jù)中心上,服務(wù)選擇不可避免的將受數(shù)據(jù)中心底層性能的影響,進而影響服務(wù)組合性能。現(xiàn)有的國內(nèi)外大部分仿真測試軟件都只能用于網(wǎng)絡(luò)層及以下各層的驗證,尚未有能支持跨層感知和協(xié)同的仿真系統(tǒng)。此外,目前的仿真系統(tǒng)無法實現(xiàn)網(wǎng)絡(luò)服務(wù)組合和選擇對云數(shù)據(jù)中心底層相關(guān)參數(shù)的感知。為此,針對網(wǎng)絡(luò)服務(wù)選擇的跨層感知仿真需求,論文設(shè)計和開發(fā)了一個面向網(wǎng)絡(luò)服務(wù)的云數(shù)據(jù)中心仿真系統(tǒng)。該系統(tǒng)不僅可以對云數(shù)據(jù)中心的各種實體進行建模和仿真,還可以完成對云數(shù)據(jù)中心網(wǎng)絡(luò)拓撲、網(wǎng)絡(luò)時延、任務(wù)執(zhí)行、動態(tài)調(diào)度等特性進行仿真,保證網(wǎng)絡(luò)服務(wù)能夠全面獲取云數(shù)據(jù)中心的底層環(huán)境狀態(tài)。論文通過對網(wǎng)絡(luò)服務(wù)關(guān)鍵算法進行研究,提出了一種網(wǎng)絡(luò)感知服務(wù)選擇算法,并根據(jù)算法仿真的需求,確定了基于開源云計算平臺CloudSim進行二次開發(fā),實現(xiàn)云數(shù)據(jù)中心仿真系統(tǒng)的基本技術(shù)路線。然后,根據(jù)服務(wù)選擇算法的網(wǎng)絡(luò)感知要求,設(shè)計了云數(shù)據(jù)中心仿真系統(tǒng)體系結(jié)構(gòu),設(shè)計了各個模塊之間的服務(wù)接口與交互流程,并完成了仿真系統(tǒng)功能實現(xiàn)與測試。論文最后基于云計算中心仿真系統(tǒng)對論文提出的網(wǎng)絡(luò)感知服務(wù)選擇算法進行了仿真,驗證了算法的有效性和仿真系統(tǒng)的功能性。論文最后總結(jié)了相關(guān)工作,并提出了下一步的研究方向。
[Abstract]:With the rapid development of network services, service selection has become an important research hotspot. With the development of cloud data center, a large number of network services are deployed in the cloud data center. Service selection will inevitably be affected by the underlying performance of the data center, and then affect the performance of service composition. Most of the existing simulation and testing software at home and abroad can only be used for the verification of the network layer and the following layers, but there is no simulation system that can support cross-layer awareness and collaboration. In addition, the current simulation system can not realize the network service composition and selection of the cloud data center underlying related parameters perception. In order to meet the requirement of cross-layer perceived simulation for network service selection, a cloud data center simulation system for network service is designed and developed in this paper. The system can not only model and simulate all kinds of entities in cloud data center, but also simulate the network topology, network delay, task execution and dynamic scheduling of cloud data center. To ensure that the network services can fully access the underlying environment of the cloud data center state. Through the research on the key algorithms of network service, this paper proposes a network aware service selection algorithm, and according to the needs of algorithm simulation, determines the secondary development based on open source cloud computing platform CloudSim. The basic technical route of cloud data center simulation system is realized. Then, according to the network awareness requirements of the service selection algorithm, the architecture of the cloud data center simulation system is designed, the service interface and interaction flow between the modules are designed, and the function of the simulation system is realized and tested. Finally, based on the cloud computing center simulation system, the proposed network aware service selection algorithm is simulated, which verifies the effectiveness of the algorithm and the functionality of the simulation system. Finally, the paper summarizes the related work, and puts forward the next research direction.
