Abstract:
Quality of service (QoS) refers to the ability to provide guarantees w.r.t. to bandwidth, latency, jitter, etc., to certain classes of network traffic. The effectiveness of QoS strategies and their implementation depend on a large number of factors, e.g., the size of the network and the complexity of services the network is intended to provide to users. In this paper, we propose a layered QoS which guarantees that the available bandwidth is assigned to users proportionate to the subscribed bandwidth even in case of congested backbone links. The key issue to achieve this is effective prioritization of management traffic. We have implemented our QoS strategy in a laboratory environment and have monitored its performance under simulated traffic. Our method has significantly reduced the total amount of packet loss. Bandwidth utilization on the congested link was increased by 60 percent.
