Performance Evaluation of Ahmadu Bello University IP-Based Network using OSPF and MPLS in a GNS3 Environment
Publication Date : 19/06/2019
The ABU IP-Based Campus Network has grown to a complex level requiring solutions that will provide more efficiency for centralized services and policies, while preserving the availability, manageability, and scalability benefits of its Campus design. Therefore, this paper presents a performance evaluation of ABU IP-based Campus Network that conventionally utilizes the OSPF protocol and also, its comparison with the MPLS protocol. The ABU Campus Network was modeled using Graphical Network Simulator (GNS3) to emulate and identify its performance and challenges. To mitigate these challenges, another scenario using MPLS-enabled was re-modeled on the same GNS3 for comparison to cater for the ever increasing demand of the Campus Network. The results obtained show that the MPLS Campus Network design is a more suitable design over the OSPF Network design, currently implemented at ABU, as it provides a more scalable and performance improvement in addressing the over-arching challenges of delays (End-to-end and queuing), jitter, throughput and server load on the Network. This has further shown that the MPLS design has the capability to accommodate more network services and devices, as well as end-users when compared to OSPF design.
