Managing the bandwidth of a computer network is always faced with great challenges. This research was
necessitated by the urgent need to manage the University network currently experiencing congestion in both the
local LA� and on the internet backhaul with a view to improving network performance and reduce the huge
recurrent on the WA� link. However, there exists various ways that have been deployed towards solving these
problems. In this paper we examined existing bandwidth management, effect of limited bandwidth on the
network performance and profound solutions of techniques that enhanced or improved the bandwidth efficiency.
Also, included in this research work are the studies of the effect of limited bandwidth on work load, type of
protocol used and the effect of network congestion on the quality of service of a Wide Area �etwork (WA�). By
comparison, from the modeling of the effect of work load and limited bandwidth on the throughput of a wide
area network based on experimental simulation and real time simulation scenarios, some observations were
made and recommendation of solutions were given from the analyzed results
