Abstract Software-Defined Networking (SDN) architecture has emerged in response to
limitations of traditional networking architectures in satisfying today's complex networking …

A software-defined network (SDN) separates the network control plane from the data
forwarding plane. SDN has shown significant benefits in many ways compared to …

In recent years, Software Defined Networking (SDN) has emerged as a pivotal element not
only in data-centers and wide-area networks, but also in next generation networking …

In modern life the internet has become backbone of digital society which is the packet
switched distributed network and connected with almost every digital devices, available …

The new network requirements are rising with internet scalability and expansion of its
coverage. The traditional network cannot support recent needings, so a new architecture …

With the rapid growth of user traffic, service innovation, and the persistent necessity to
reduce costs, today's mobile operators are faced with several challenges. In networking, two …

In this paper we address the problem of Software Defined Networking (SDN) controller
placement in large networks. Indeed, to solve the scalability issue raised by the centralized …

Software-defined networking (SDN) is considered one of the most promising development
modes of the future Internet because of advantages such as programmability and …

In a multi-controller SDN, the network state is replicated or distributed between the
controllers requiring repeated synchronization. This synchronization cost depends on …

Software-defined networking (SDN) is a networking architecture with improved efficiency
achieved by moving networking decisions from the data plane to provide them critically at …
