Study On Technology Of Virtual Resource In Virtualized Switch Management And Optimization

The conventional network based on TCP/IP faces a range of difficulties in flexibility, scalabilityand manageability. In order to take experiment some new alternatives in the Internet core and tosupport future network innovation, it is imperative to verify the architectures of the future internetand associated protocols in a real network environment. Researchers have put forward the idea ofnetwork virtualization. It has received widespread attention. In the research of networkvirtualization, it is crucial to find an efficient way to manage virtualization resources.This thesis analyzes the technology of development and implementation for virtualization ofswitch with NetFPGA. It combines XenServer virtualization software with NetFPGA. This thesisfirstly develops a NetFPGA driver module in XenServer DDK environment, then deploys the drivermodule into XenServer Domain0to create physical switch with four Ethernet networking ports.The thesis constructs a virtualized switch by network bridges between virtual network card andphysical network card. Then it verifies the effectiveness of the virtualization of switches by theexperiment of the allocation and deployment of two independent virtualization of switches.Secondly, in order to make virtualization of switches provide better network performance, the thesisdesigns an approach to monitoring virtual resources, and completes the function of sensing andmonitoring that communicates with a global resource management entity. Finally, aiming at fairnesscontrol by a conventional management tool for the physical bandwidth resource shared by virtualswitches, this thesis provides a scheme on flow shaping and a brief verification over a testingnetwork.
