Virtualization is an imminent sector of the Information and Technology in the peresent world. It is advancing and being popuraly implemented world wide. Computer network is not isolated from the global impact of the virtualization. The virtualization is being deployed on the computer networks in a great extent. In general, virtualization is an inevitable tool for computer networks. This report presents a surfacial idea about the impact of the virtualization on the computer network. The report enlightens about the measurement of the some popular network performance metrics. The report describes the experiments which has been separately conducted on a bare metal environment and virtualized platforms. The analysis and comparison between these two experimental issue is covered on this document. The web server is a most prominent entity of the computer so that to address a little bit more scenarios, the performance measurement of the web server is explained. Thus, the report is reflection of the two fold task, measurement of the performance of the computer network along with measurement of the performance of web server. In addition, the document provides basic information about the influence of virtualization on a small private computer network.
