Development of monitoring system for end-to-end packet delay measurement in software-defined networks

In this paper the concept of network monitoring implemented in SDN architectures are explored. This new programmable network architecture ensures a significant advantage over other because it is introduce new functionalities and easier to tune up to provide guaranteed quality of services from end-to-end for each priority flow. Monitoring the network is the first step towards a SDN forwarding protocol capable to ensure sufficient QoS for all types of applications and traffic. A new measuring method for packet delay has been proposed. The method is capable to provide statistics for every different type of service that passes through the network.
