Development Of An Acceptable Use Policy Framework For Ibbul Communication Network.
ABSTRACT
Bandwidth utilization in a campus network if not properly managed, may lead to the congestion of the network bandwidth. This research work presents a bandwidth control system implemented at the access layer of a campus network which is aimed at reducing the processing time at the core of the network.
Ibrahim Badamasi Babangida University Lapai (IBBUL) campus network was monitored and data were collected on a daily basis between 12 am to 11 pm over a period of 60 days (from 1st September 2014 to 30th October 2014).
Analyses of these data were carried out which include:
(i) peer-to-peer (p2p) activities,
(ii) user traffic analysis and,
(iii) web analysis.
The analyses revealed the highest and lowest p2p activities of the users across the monitored nodes, as well as the time of day they occurred. It also revealed the nodes with the highest traffic and the time of day it usually occurred. Based on these results, the IBBUL network scenario was modeled and simulated using Graphical Network Simulator 3 (GNS3).
A star network topology with a Juniper EX4200 core was modeled. Juniper EX2200 series switches were modeled as the access layers. A number of host computers with various specifications were also attached to these switches and all the devices were configured appropriately.

INTRODUCTION
This chapter discusses the network structure of IBBUL, the type of devices used in the network, as well as the challenges facing the network with respect to bandwidth management.
With the use of wired or wireless connectivity, instant access to email, the Internet, and other IT services have dramatically changed the way people live, work, and study.
To this end, students, staff, and visitors always expect easy access to most information and services of an institution. While academic institutions are characterized by the high rate of electronic file sharing and Internet surfing,
Ibrahim BadamasiBabangida University, Lapai (IBBUL) as a fast-growing institution is not exempted from such demand. These demands can only be met effectively with a robust bandwidth management policy.
