Among these SPE process, we focus on load generating of performance testing. There are many load generating tools like Load Runner [13] and Silk Performer [14]. However, tools cannot cover every testing scenario. In a server/client environment, client sends information to server generally. However, server may send information to client. Existing tools cannot support that scenario. If a tool does not understand communication protocol, it cannot generate load and if DUT[2] uses new technique that tool does not support, it cannot
generate load. In those situations, we cannot use existing load generating tool and we may have to use many real computers and lot of people are required to operate software on those computers which is not

Architecture of the tool
The overall architecture of the tool is presented in Figure 1. Virtual computers are generated from real server. The number of virtual computers generated from a real server depends on the scenario under which the DUT[2] is to be analyzed. Each Virtual Computer has a different IP Address. Thus, each virtual computer acts as an individual client. The user (tester) just interacts with the physical computer and executes the python scripts present. These scripts activate the virtual computers which interact with the DUT[2] and generate traffic depending on the profile which the user selects before the test begins.
Virtualization is a technique that abstracts computing resource. It enables the users to create a simulated environment and use the resources effectively. Virtualization is divided into several categories as purpose such as server virtualization, network virtualization, desktop virtualization, application virtualization and so on [15]. In this paper, we use desktop virtualization technique to perform software performance test. There are a lot of desktop virtualization products such as VMWARE [16], Virtual PC [17], Parallels [18], Virtual Box [19] and so on. We selected VMWARE because it is the most frequently used product and it uses computing resource efficiently. It enables the users to use all the CPU cores effectively. It also has high compatibility with various
Answer the following questions based on the packet capture that precedes them. You may research any of these on the Internet if you need to do so.
Network Based Virtualization is abstract storage of data applications from the host machine. This is well achieved through fibre channels connection between the machines and the servers running virtualization. The respective operating systems on the separate machines are not a factor to consider as they work independently. For it to achieve its expectations, the following services must be provided as below:
software has lot of importance in recent years. A number of tools are available for testing network and communication protocols. NetIQ’s ANVL(Automated Network Validation Library) is to test routers and other networking products. The software generates packets in correct and incorrect formats to test the networking software.
As we all know virtualization is the requirement of future. We have evolved from the age of traditional environment to virtual environment.We have grown accustomed to almost all things virtual from virtual memory to virtual networks to virtual storage.The most widely leveraged benefit of virtualization technology is server consolidation, enabling one server to take on the workloads of multiple servers. For example, by consolidating a branch office’s print server, fax server, exchange server, and web server on a single windows server, businesses reduce the costs of hardware, maintenance, and staffing.
VMware provides the vSphere application and similarly Microsoft provides Hyper-V application for the purpose of virtualization. Most of the major datacenter in the world use the VMware as their solution for virtualization. VMware dominates the server virtualization market in world due to its innovations, strategic partnerships and rock-solid products [2]. We shall be using VMware products to virtualize the hypothetical organization. The reasons for choosing VMware [3] are:
This tool is what’s known as a Network Mapper. This tool is mainly used as a network discovery scanner and as a security auditing tool. This tool can determine the availability of hosts on a particular network through the use of raw IP packets. The tool can also determine what services ( including application name and version) the hosts is offering, as well as what OS and versions they are running. This tool can also determine the type of firewalls and/or packet filters that are in use, and other important characteristics of the network environment.
This type of computing even makes use of other resources such as SANs, network equipment, and security devices. It can also support applications that are accessible through the Internet. These applications make use of large data centers and powerful servers that host Web applications and Web services.
To test the performance of an ESXi host in the form of memory, CPU, and network
Testing is accomplished on an Intel Xeon, 6x2 Cores, Dual Processor with 32 GB of RAM, 2TB secondary storage of capacity. Operating system is 64 bit MS Windows Server 2008. Testing is being performed on five
This lab is extremely important for the real world. A good majority of companies run their server infrastructure on Windows, which means becoming familiar with the technology and services that run on it is just as important as knowing them on Linux. This lab has honed our skills in that regard.
Network communication is an increasing phenomenon as associated technologies are improving. This is very important in the all aspects of life. In present time, there is a lot of traffic over various kind of networks. Due to this, the network performance gets compromised. There are wide range of network performance and traffic generation tools available and these are very useful for the network administrator. With the help of these tools, they can monitor and test network performance. However, it is not an easy task to find an appropriate tool and start checking performance related attributes. It is like looking for a needle in a haystack due to the large number of availability of these tools. It is very difficult to find tools that are suitable with desired characteristics and features.
The idea of developing such product that automates routing and helps in analyzing network came from the troubles that a network administrator had to face in resolving network issues in the backbone of the Internet. External Gateway Protocol (EGP) are incapable of adjusting to the network anomalies easily. Moreover, hackers can also introduce delays, loops that affect the network connectivity and operations. Hence to resolve these issues at faster rate the network administrator requires a
The Server virtualization process involves physical partitioning of the server into more subdivided and smaller manageable server units to maximize the resources available in the server. Server virtualization helps conserve space through consolidation by recreating a single server to operate as a server running multiple virtual environments. This enhances full resource utilization thus saving operation cost by reducing the hardware maintenance because of the diminished
Virtualization combines or divides the computing resources of a server based environment to provide different operating environments using different methodologies and techniques like hardware and software partitioning or aggregation, partial or complete machine simulation, emulation and time sharing (Uddin and Rahman, 2011:69) meaning less hardware will be required to run a number of applications.
