The Virtual University, Pakistan’s first University based completely on modern Information and Communication Technologies, was established by the Government as a public sector, not-for-profit institution with a clear mission: to provide extremely affordable world class education to aspiring students all over the country.

Using free-to-air satellite television broadcasts and the Internet, the Virtual University allows students to follow its rigorous programs regardless of their physical locations. It thus aims at alleviating the lack of capacity in the existing universities while simultaneously tackling the acute shortage of qualified professors in the country. By identifying the top Professors of the country, regardless of their institutional affiliations, and requesting them to develop and deliver hand-crafted courses, the Virtual University aims at providing the very best courses to not only its own students but also to students of all other universities in the country.

Abstract

Minimum end-to-end delay, packet delay variations or packet jitter, and packet drop for given throughput in fixed and wireless networks are well-known important factors. These factors play important role in achieving better Quality of Service (QoS). Furthermore, these also have evident effects on network utilization, efficiency and better Quality of Experience (QoE) for services being carried over networks. Traffic intensities (TI) are generally used for dimensioning and capacity planning in telecom networks. Generally, TI depends on point of presence (POP) and its characteristics. These characteristics include type of area served, customer density, usage pattern and grade of service (GOS). Most of time, for TI in busiest hour is used to determine required capacities of network resources. This thesis research work extends concept of traffic intensity for period-to-period base rather than busiest hour and utilize traffic intensity being offered for packet scheduling in wireless and wired networks. This will provide an opportunity to manage packet forwarding decisions based on dynamics of planned Traffic intensities for given POP and will enable us optimize forwarding decisions and hence optimize delay, jitter, drop behavior of network nodes. To evaluate effects of packet scheduling based on TI, a model network was simulated using NS2 and Traffic Intensity Based Packet Scheduling (TIPS) algorithm was used to schedule packets from various sources to common destination. During analysis impact on end-to-end delay, jitter, and throughput and drop behavior of network nodes was evaluated and compared with various other available approaches. It is found that TIPS offers optimized results for better QoS and network utilization as compared to existing packet scheduling approaches like Drop Tail, Round Robin, Deficit Round Robin, RED and SFQ. This thesis document will provide details of packet scheduling methodology, TIPS algorithm, simulation results and their comparison with above packet scheduling algorithms.
