What this means is that although the new network provides a massively increased pipeline, the clients seem to want to have their own services, self hosted and managed, that they can provide for their students. The smaller the organization, the more they want SAAS applications available On-net, the larger the organization, the more they want their own, controllable environment. Recommendation Providing a service that can run as a local Real Time Communication service so that any local data is kept inside the local network will provide lower latency and a controlled environment. Communication from the local server to a central server for cross institute, cross jurisdictional real time communication can be achieved using an Origin server. This is sometimes referred to as an Edge/Origin strategy. This will also allow the organizations to brand their local version of the Real Time Communication applications.

5.2.3 Bandwidth Considerations From a bandwidth point of view, most locations did not experience a major difference unless connected directly to the pipeline as local machines and networks were often throttled down to help provide quality of service or at least a more equal shared network environment to stop heavy users dominating the bandwidth, which resulted in users being able to do basic functions like checking email etc. without being affected by another user downloading huge files. A major unseen benefit is the massively reduced latency when using these applications between on-net users. As many of the application users where both on-net and commodity internet users, the fact that on-net traffic reduced latency by an incredible amount and allowed large video formats as more users at once was not as apparent due to the students accessing the applications form either home or work where they are limited by the commodity internet providers that they are connected through. There is no immediate solution to this except to recognize that to make the most of this latency benefit means making the most of applications between on-net sites while recognizing that commodity internet users will lag behind. Recommendation Making sure that clients are aware of the bandwidth limitations imposed on their local pc’s will allow them to understand why a real time service is not responding as well as they had hoped and providing an approved solution to increased bandwidth, decrease latency, if it is required by the client. 5.2.4 Bandwidth Calculations From the results of this project and ongoing testing we are able to estimate the bandwidth usage for a typical scenario using video and audio conferencing on a personal computer across the network. This also allows us to calculate the server load and bandwidth requirements to and from the server. The following scenarios are provided as a guide only.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
