- Abstract
- 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 overhead 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. In addition, a complex combination of multiple and heterogeneous management channels further aggravates the scalability problem. In this paper, to address the above management problems. We propose an intelligent management middlebox called Software-defined Unified Monitoring Agent (SUMA). SUMA builds a hybrid SDN architecture by providing intelligent control, management abstraction, and a filtering layer, that eventually will serve as an essential component for the reliable, scalable, and secure SDN deployment. In this paper, we present design, implementation, deployment, and evaluation results of a SUMA. © 2014 IEEE.
