Network performance evaluation by using packet tracer or NS tools

As computer networks are growing, wire and wireless networking technologies are developing, As technology are improving, the requirements of users for fast network performance and security of network are increasing day by day. In this study, the performance of networks will be examined. Therefore what can be done in a network performance evaluation using some simulation tools such as network simulation or packet tracer. And these information will be presented that how various parameters can be brought side by side together successfully. CCNA, CCNP, HCNA and HCNP educational level has been used and important adjustment has been designed and simulated one by one. As a result this is a usefull guide for a local network and wide network. The proposed remote network in this lab architecture based on virtual technology showed more benefit than traditional laboratories using real equipment, which is especially important for network simulations. In addition to the experience gained here, operations can be performed on a network. We are re-cabling virtually laboratory equipment here. We could apply a new design by changing the topology of the laboratory and adding virtual laboratory equipment. The virtual laboratory brings all the functions of real equipment. This lab solution is mostly suitable for educational because network traffic is light and lab is usually strong to come from the top of PC load, and a particularly impotant eagle server is DHCP, Mail, FTP, Web buttons and distributors, and networking equipment such as security devices and PCs provided by a linux based machines provides benefits for us. In this study, we tried to integrate virtualization applications such as linux based eagle server and and WMware into virtual cisco device simulation. Finally, the performance issues precautions described. Considering the necessary parameters, imaginary networks were designed and evaluated in both CISCO Packet Tracer and Huawei's eNSP simulation program. But it should not be forgotten that the designed networks were designed and evaluated in free virtual environments, not real laboratories therefore, it is not possible to make actual performance appraisal and output as there is no actual data available. Only the performance requirements are taken into consideration and the network performance is assessed by evaluating as much as the virtual environments permit.
