A Web-Based Management System for Software Defined Network Controllers

摘要

Auto-reconfiguration and response mechanisms in IP networks are challenges that lead to enforcing the required policies in such a dynamic environment. Software-Defined Network (SDN) provides an economic architecture solution for service providers by reducing provisioning time from weeks to minutes, facilitating centralized management, allowing programmability and promoting innovation. SDN achieves this by separating the two features inside network devices, such as routers and switches, namely the control plane from the data plane. The paper presents an implementation of a web-based management system for SDN controllers. This implementation allows network operators to control and supervise quickly the virtual network functions (VNF) provided by SDN networks. The implementation not only takes advantages of open source software including Flask and Ryu frameworks, OpenvSwitch and Mininet but also supports for virtual network functions. The system emulates a network topology with simple switches and links and also acts as a management center to query commands from Ryu network application using REST API in order to monitor changes in network traffic.
