Abstract

The article identifies the appropriate network monitoring methods to be explored to propose new SDN fault schemes and explains in detail the basic principles of OpenFlow. Detection of network failures is a serious problem for each operator and is based on the human factor. In order to reduce the time of failure detection, new methods for SDN architectures are needed. There are several approaches to network measurement and monitoring, which are based on the insertion of additional layers between devices and the network controller. This allows for the control of OpenFlow control messages, for example, to identify traffic overload. Since the extra layer differs from the original OpenFlow architecture and requires additional hardware, the analysis of the flow of records on the network controller - this can be achieved by deploying monitoring algorithms that operate on the basis of the network controller. Flow analyzes can be used to detect traffic characteristics and build a complete picture of the network by including incoming signals from all network devices. Also presented is the concept of Software-Defined-Networking.

Keywords: information network; software-configured network, information security; SDN; Linux; Ethernet; OpenFlow.
