Qualidade de serviço usando o algoritmo Token Bucket

Abstract

Quality of Service (QoS) in Computer Networks, has as one of its objectives to limit internet traffic from specific devices, making it possible to have greater control over the network. But the routers and switches used in networks do not impede Quality of Service (QoS) control and their configuration can be challenging. Therefore, this work aims to analyze the configuration parameters of the Token Bucket, which is a mechanism that allows limiting the available bandwidth for the end user or for a network equipment such as a router and switch. The parameters of the algorithm are the bucket rate, the bucket size and the input buffer size. Through simulations using the mininet simulator, it is possible to observe that as the bucket size increases, the packet transmission delay increases and that there must be a minimum input buffer size to avoid packet loss.
