VIM-SUMA: Virtual infrastructure management-software defined unified monitoring agent

Providing the programmable control interfaces, Software-Defined Network (SDN) enables agile network traffic control and configuration as well as shortens the network function deployment time. Despite the projected benefits of SDN, the abstractions toward the remote and centralized control tend to impose excessive control traffic overheads in order for the controller to acquire the global network visibility as well as to extend the legacy network´s inaccurate and unreliable management problems into the control plane. To address such complex management problems, efficient and intelligent traffic and resource monitoring is an essential function. In this paper, we propose an intelligent traffic and resource monitoring middle-box called Virtual Infrastructure Management - Software-defined Unified Monitoring Agent (VIM-SUMA). It assists to build a scalable, reliable, and efficient SDN architecture by providing intelligent management abstraction and filtering layer. We present design, implementation, and evaluation results of VIM-SUMA.
