As a part of this experiment, four different media applications were analyzed for network performance. They are:
1.YouTube: YouTube is a video-sharing service that uses the process of dynamic adaptive streaming over a HTTP protocol to enable two serial client-server processes to allow the user to access video content.
2.Blackboard: Blackboard is an emerging educational tool, used by academics all over the world to provide streaming services for students, allowing file-sharing, live examinations, interactive video, etc. It is similar to YouTube in the sense that two serial client-server processes are used in the protocol, but certain salient features of this application enable peer-peer communications, which will be the focus of this study.
3.Skype: Skype is a video-call hosting service, in which users can access audio or video or both while conversing with an end user. Since the new features of Skype also include interactive live sessions, the network performance analysis of the comparison of audio-only, video-only, audio-video dual and interactive audio and video sessions will be of significance in addressing the context of this paper.
4.Google+ Hangouts: Google+ Hangouts is similar to Skype, except that it is hosted over an email network. Thus, the internal architecture of this media application is quite complex, and is of consequence in improving the current efforts to provide a dynamic network that can support both streaming media and real time media applications with optimal performance.
For the sake of the experiment, the Wireshark network software was used to measure the performance of the network while the specifications of each of the five experiments were being tested. The differences in the nature of these applications and the characteristics of the network performance under each experiment will be compared and put in appropriate context. This is also with the purpose to test the hypothesis that the network protocol utilized by each of these applications carries the characteristics of each of these applications in different characteristic ways. Wireshark, thus, offers potential for a wide variety of quantization calculations to be performed to extract the features of the network that are most suited to the purpose of the study. Thus, the conceptualization of various existing and required network performance parameters is also essential.
