Review of Differentiated-Services Architecture for QoS-Aware and Delay-Sensitive Campus Area Network (Case Study of Ahmadu Bello University, Zaria)
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 7
Abstract
University networks are mostly designed to support best-effort data applications, but demands by the university’s faculty, researchers, students, administrators, and staff to discover, learn, reach out, and serve society expect the networks to run voice, video and other multimedia traffic over it as well. In today’s networks, the widespread use of real-time and multimedia traffic applications demand special service guarantee in terms of throughput, delay, and delay variance, thus making quality of service (QoS) a key problem. For multimedia packets to travel seamlessly on the network and for the network to meet the demand for higher performance by applications; Voice, video and other multimedia packets must be given priority in term of packet delay and packet delay variance over other, less-time-sensitive traffic, such as e-mail or Web browsing. In this paper we present the review of development of a differentiated services computer networking architecture for packet delay and packet delay variance reduction in a campus area network. Using management tools that can be used to provision and monitor set of routers in a campus network in a coordinated manner, which can classify and apportion network traffic give preferential treatment to applications identified as having more demand requirements. This scheme is capable of differentiating between delay sensitive and best-effort traffic and route packets accordingly. Keywords: Best-effort, differentiated services, quality of service, packed delay, packet delay variance, network architecture.
