Controlling network congestion is a very urgent task while securing queues in resource reservation systems. This is one of the key elements, as many controllers were introduced to control overload to solve the problem. This article analyzes the impact of network workload on the performance of various active queue management controllers, including the traditional Drop Tail controller, to ensure that queues are protected from congestion in resource reservation systems. This paper presents an analysis of four possible scenarios with the same network parameters except for the network workload. The performance of each controller is measured using various performance metrics. The effect of network traffic load on the performance of network controllers can be easily observed in the four presented scenarios. The behavior of all controllers clearly indicated the effect of network traffic load on their performance. The results showed that the load on network traffic is directly proportional to bandwidth, packet loss and delay. The results can be used to create fault-tolerant resource reservation systems.

Keywords: workload, network, queues, controller, resource reservation.
