| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 102 === Along with the rapid development of the Internet, the distributed architecture of legacy networks has increased network complexity and the cost of maintenance. Traditional network cannot meet the requirements of current users. To meet the requirements and improve the quality of various network application services, Software-Defined Networking (SDN) has been developed.
SDN technology has already been used successfully in many cases. In SDN architecture, network intelligence and state are logically centralized, and the underlying network infrastructure is abstracted from the applications. As a result, SDN provides the benefits of programmability, automation, and network control it. It also realizes the concept of network virtualization, through which network resources can be shared. Therefore, this work concerns the allocation of network resources on a network virtualization platform. This work presents a dynamic resource allocation mechanism in EnterpriseVisor based on the proposed network virtualization platform, to deploy the network resources based on an analysis of the resource utilization of each network slice.
This work analyzes the proposed dynamic resource allocation mechanism in EnterpriseVisor. First, the EnterpriseVisor monitors the resource utilization of each slice. Second, based on the results, the mechanism of EnterpriseVisor analyzes the utilization of each slice. Then, the slices will be classified as providers or requesters. Finally, the EnterpriseVisor will perform resource planning by minimizing cost and translating into resource allocation policies. Based on the results thus obtained, the proposed EnterpriseVisor overcomes the bottleneck of slicing technology and improves resource utilization by 13.4% and 25.7% over those achieved SDN using the slicing technology and SDN without slicing technology.
