Abstract Introduction of circuits into the packet-switched network influences the QoS of the packets transported hop by hop. This report focuses on the correct dimensioning of two types of circuits in a butterfly network with different loads. The results show that depending on the load and routing mechanism, introduction of circuits can bring benefits for both the packets transported by the circuits and the packets transported by the packet-switched network with reduced resources. Packet switched networks are very efficient in terms of utilization of network resources, but the service they provide is usually dependent on the traffic conditions. Traffic in the Internet is hardly predictable, and so is the endto- end transmission delay of packets. Moreover, each hop on a packet route is a potential congestion point and may cause variation of the transmission delay or even packet loss. Usage of a circuit in an IP network guarantees a constant delay and no losses between its edges, namely high and predictable QoS. An investigation of influence of circuits in the packet switched network was performed in this report, with the focus set on circuit dimensioning. It was shown that circuits in the Internet can decrease packet transmission delay and losses, while increasing throughput, if lowly utilized links are used to establish a circuit.
