Abstract:


The Kuwait Civil Service Commission (KCSC) built an enterprise to allow clients to access those systems. This network covers two buildings: Headquarters (HQ) and Disaster Recovery (DR). In addition, the KCSC network covers more than 250 sites, including all ministries and other governmental agencies. This analysis studies the Local Network Area (LAN) for KCSC using OPNET. The following network parameters are investigated in order to identify any network performance issues: network delay, throughput, packet drops, and jitter. The main results of this analysis show an average network delay of 0.2 ms without any packet drops and a maximum network traffic of not more than 2.2 Gbps, indicating that there is no congestion. Some network jitter appears, affecting VOIP service. The most critical design issue in the KCSC LAN is a lack of redundancy links between core switches and server farm switches, which have very little effect on the redundancy of the network.
