INTRODUCTIONNetwork performance can be defined as review or analysis of network statistics in orderto define service quality provided by the computer network [1]. It also helps in defining as wellas measuring performance level of a network. It also helps in measuring, improving and guidingnetwork services. Network performance can be used for discussing performance issues,deployment issues associated with the network [2]. This assignment will lay emphasis oncapturing of Wireshark data in order to discuss performance of distributed system behind givenweb system with the help of flow graph, time sequence graph, throughput graph, loaddistribution and windows scaling graph. Analysis of this data will be done with the help ofWireshark tool. Other than this analysis of output of audio streaming website will also be done inorder to measure its performance. TASK 1Three websites performance analysisWireshark: Wireshark is an open source, free packet analyser which is used for analysis, troubleshooting, development of communication protocols and for various other things [2]. It has agraphical front end with integrated filtering and sorting options. It runs on different platformssuch as windows, Linux, MacOs and various others. Website 1: http://www.onlinenewspapers.com/australi.htmIt has been determined that ip address of http://www.onlinenewspapers.com/australi.htmwebsite is 52.23.105.176. Wireshark tool has helped in analysing and capturing packettransmission.Load DistributionFigure 1 Onlinenewspapers load distributionIn the above load distribution table rate, percentage and burst rate, average count,capacity of the network has been shown.1

Throughput graphFigure 2 Onlinenewspapers throughput graphThe above throughput graph helps in calculating average throughput (bits per second) ofthe website by calculating segment length per second. It has been observed that highest averagethroughput of the website is between 0.5 second to 1.5 second.Time Sequence graph2
