The paper presents a survey on OpenFlow related technologies that have been proposed as a means for researchers, network service creators, and others to easily design, test, and deploy their innovative ideas in experimental or production networks to accelerate research activities on network technologies. Rather than having programmability within each network node, separated OpenFlow controllers provide network control through pluggable software modules; thus, it is easy to develop new network control functions in executable form and test them in production networks. The emergence of OpenFlow has started various research activities. The paper surveys these activities and their results.

As a result of large-scale and complicated of ICT (Information and Communication Technology), the technologies of operations and management of ICT infrastructure and systems are changing to adopt the variation and diversity of usage and communication characteristics. In retrospect, operations and management technologies cover widely from the support of telecommunications operations and remote monitoring for maintaining network equipments, to an integrated network management framework for configuration, monitoring, testing and controls. Recently, the spread of network virtualization technologies enable agility, integrity, and resilience to ICT services. Operations and management technologies will be more important in future, for the support of integrated management of ICT infrastructure including computing resource, and automation of service operations. In this paper, we review research activities of the Technical Committee on Information and Communications Management (ICM) with discussions of individual research category. We then describe the state-of-the-art topics and future directions in the area of ICM.
