Impact of queue tree and layer 7 filtering combination to bandwidth management in 802.3 Network

Abstract

Bandwidth management on commercial local area network should be maintain as efficient as possible so that users connections experience best performances and are treated equally and fairly to support business activities. Unsuitable bandwidth management may cause unstructured user management and lead to bandwidth degradation during busy hours. Some users may occupy network more than the others. Some existing works have proposed bandwidth management approaches. This paper combines queue tree and layer 7 filtering by applying traffic priority, committed information rate (CIR) as well as applying specific data pattern to preserve bandwidth. As results, at the evaluated network, the combined method guarantees in average 2 mbps bandwidth for upload/download traffic with average CIR 250 kbps per client. The ICMP test produces average 20 ms delay which is in excellent category. Average jitter 18 ms and packet loss is zero. Further, specific data pattern implementation is able to preserve the total 20 mbps available bandwidth without omitting the CIR guarantee in each client.
