Hybrid optimisation for managed network services

One of the solutions to overcome the network congestion issue over the WAN is to deploy QoS. However Service Provider rarely utilized the QoS function to avoid any implication on the network because it requires high maintenance and attention from network administrator. Usually they would propose customers to add more bandwidth due to congestion but it would only resolve the congestion issue temporarily and application performance would still be an issue. This paper presents the performance evaluation on hybrid optimisation which combines both network-based QoS and WAN Optimisation solution to overcome the congested link issue over the WAN. The headquarters and branch office connection were setup over the MPLS VPN on our test lab to simulate the congested link. The performance of the proposed method was evaluated by measuring the network and application throughput, round-trip time, efficiency and utilisation. The results presents that the proposed hybrid optimisation was able to reduce bandwidth utilisation at 53% over the congested link. The proposed method was useful to managed network service provider to customize their managed service as well as improving the network efficiency and provide optimum level quality of service to enhance their end user experience.
