Description
Summary:碩士 === 國立中興大學 === 資訊科學與工程學系所 === 100 === In cloud computing, virtualization is accomplished by equipping with a virtual switch to connect between physical machine and virtual machine. The virtual switch which is usually written coded in software provides a flexible configuration and management. In this paper, we use kernel based virtual machine (KVM) to deploy the virtual server cluster and apply Open vSwitch for the virtualized network environment. Our platform provides service with single entry point so that the virtual server cluster is fully transparent to end users. The implementation of load balancing is carried out by using Open vSwitch with an Openflow controller. Openflow controller dynamically manages the flow table in Open vSwitch through secure channel by Openflow protocol. With the platform, we can also deploy a virtual cluster across two Local Area Networks (LANs) through Generic Routing Encapsulation tunnel protocol. Upon a request, the Open vSwitch forwards the traffic to the virtual server cluster upon the loading policy to achieve load balancing.
