Measuring the performance of the OpenFlow controller in the experimental sample of the network

The OpenFlow protocol is the main technology formed among the first concepts of software-defined systems. This technology makes it possible to develop external software shells necessary for increasing the functionality of switching, routing and information processing processes, not depending on modern equipment and firmware versions and formed separately by an external controller. One of the main tasks of the work that needs to be done is to study changes in packet delays on the FloodLight controller, which does not have a flow table of the OpenFlow switch. In addition, it is necessary to find out the packet loss in the experimental network sample in the Mininet virtual environment. The study was conducted using some modern tools and technologies, and an analysis of the domain and requirements was previously carried out. Based on the results obtained experimentally, some conclusions were drawn and some recommendations on the use of the OpenFlow protocol in early stages of development for small networks were made.
