Modelling of SDN switch with OpenFlow protocol in AnyLogic

Abstract

Background. Low flexibility and manageability of software control of network equipment is one of the problems of modern networks. In order to solve this problem, software- defined networks (SDN) are used, the main component of which is switch with OpenFlow protocol. The purpose of the study is to model a SDN switch with OpenFlow protocol in AnyLogic, in order to obtain the transmission characteristics of SDN, experimentally evaluate these characteristics. Materials and methods. The article considers the simulation model of SDN switch in AnyLogic. The main components of the switch, such as flow tables, rules of packet actions on the input and output ports of switch, control processor, switch queues are briefly described. The work of the scheme with SDN switch and OpenFlow protocol is debugged. Tests are performed, data are measured, and the advantages of the presented model are described. Results. The research analyses the processes of traffic management and network equipment configuration using OpenFlow protocol, builds a model and identifies potential areas of application and prospects for the development of this model in SDN. The results obtained can be used for optimization of SDN operation and development of effective methods of network traffic management. Conclusion. The model of SDN switch with OpenFlow protocol was considered. Positive and negative aspects of the model using OpenFlow protocol in SDN were revealed, and the decision to increase the network bandwidth to improve the efficiency of the model was demonstrated.
