【摘要】：隨著網絡規(guī)模的急劇擴張和各種新興網絡技術與網絡業(yè)務的不斷涌現(xiàn)以及用戶對網絡需求的轉變,傳統(tǒng)網絡架構所面臨的網絡架構僵化、技術革新困難、服務質量難以保證等問題日益突出。網絡虛擬化技術通過在共享的底層基礎架構上并行部署多個虛擬子網，保證網絡穩(wěn)定性的同時加速網絡技術的革新和應用，成為解決現(xiàn)有網絡問題的一種有效途徑。然而，面對虛擬網絡的動態(tài)服務特性，如何實現(xiàn)對底層物理資源的高效管理以滿足各個虛擬子網的資源需求，同時實現(xiàn)底層物理資源利用率最大化，成為了網絡虛擬化研究的關鍵問題。 為了解決資源高效管理問題，本文首先對網絡虛擬化現(xiàn)有的資源管理架構研究成果進行了重點研究，并分析了這些資源管理架構存在的不足。在此基礎上設計了一種多層混合式資源管理架構MHVRM，旨在提高網絡資源的管理效率和可擴展性。該架構通過建立一種分層式管理和分域式控制的資源調度服務模式來實現(xiàn)對業(yè)務請求的靈活、高效、可擴展和智能化部署。為了解決虛擬網絡映射問題，本文在分析控制轉發(fā)分離架構下物理節(jié)點資源基本特征的基礎上，以實現(xiàn)底層物理網絡資源利用率最大化為目標，在控制轉發(fā)分離網絡構架下建立了基于路徑分裂的用戶優(yōu)先級虛擬網絡映射模型，針對不同的虛擬網絡請求，設定不同的優(yōu)先級，采用不同的鏈路映射策略來實現(xiàn)虛擬網絡的部署。最后，本文通過VS2008仿真軟件來建立仿真平臺對所提出的模型和算法進行多方面指標的性能仿真和驗證，證實了所提模型和算法在解決虛擬網絡映射方面的高效性和優(yōu)越性。
[Abstract]:With the rapid expansion of network scale, the continuous emergence of various emerging network technologies and network services and the change of users' demand for network, the traditional network architecture is faced with rigid network architecture and difficult technological innovation. The quality of service is difficult to guarantee and so on. Network virtualization technology is an effective way to solve the existing network problems by deploying multiple virtual subnets on the shared underlying infrastructure in parallel to ensure the stability of the network and accelerate the innovation and application of the network technology at the same time. However, in the face of the dynamic service characteristics of virtual network, how to efficiently manage the underlying physical resources to meet the resource requirements of each virtual subnet, and at the same time to maximize the utilization of the underlying physical resources. It has become a key problem in the research of network virtualization. In order to solve the problem of efficient resource management, this paper first focuses on the research results of the existing resource management architecture in network virtualization, and analyzes the shortcomings of these resource management frameworks. On this basis, a multi-layer hybrid resource management architecture, MHVRM, is designed to improve the efficiency and scalability of network resource management. The architecture can achieve flexible, efficient, scalable and intelligent deployment of business requests by establishing a hierarchical management and domain-controlled resource scheduling service model. In order to solve the problem of virtual network mapping, based on the analysis of the basic characteristics of physical node resources under the separate control and forwarding architecture, this paper aims at maximizing the utilization ratio of the underlying physical network resources. Based on path splitting, a user priority virtual network mapping model is established under the framework of control and forward separation network. Different priorities are set for different virtual network requests. Different link mapping strategies are used to implement the deployment of virtual networks. Finally, this paper establishes a simulation platform to simulate and verify the performance of the proposed model and algorithm through VS2008 simulation software, which proves the efficiency and superiority of the proposed model and algorithm in solving virtual network mapping.
