Abstract
Software Defined Networking attempts to use software defined packages or modules for implementing network features/functions and their control and management. It utilizes the concept of separating the network control plane from the network traffic forwarding plane. The control plane can be physically distributed, but it is logically centralized. SDN decouples the physical networking infrastructure/resources from the services that utilize them so that flexibility and programmability in a resources’ assignment can be achieved seamlessly for the desired applications and services. However, there are a number of network management issues to be explored as to how developers and engineers should design, build, and manage networks from the existing networks, and what and how new functionalities can be offered. We received a large number of submissions from seven different countries. We have gone through a rigorous review process and all the papers received at least two reviews. Ultimately, we selected five papers from the open call, and an invited paper from the industry. This special issue covers a wide scope of SDN management including a transport network, a broader abstraction platform, a hybrid architecture with a legacy network, a multi-domain architecture, multicast, and end-host management. Some of them are near or already at the operational/deployment stage.
