IEEE ComSoc CTN Special Issue on Software Defined Networks & Virtualization Trends in Communications

CTN Issue: August 2014

Anywhere you look in the Communications Technology Industry – mobile networks, content delivery, home connectivity, wireless, enterprise, IoT, data centers, cloud computing and backbone networks – you see and hear about “Software-ization” as one of the most important transformational forces underway in the industry. This trend is most commonly refereed as Software Defined Networks (SDN) and network Virtualization/Network Function Virtualization (NFV).

Interfaces, Attributes, and Use Cases: A Compass for SDN

CTN Issue: August 2014

The term Software Defined Networking (SDN) is present in most discussions about the future of communications technology, and it means different things to different people. Thus there isno consistent definition at this early stage of its technology development lifecycle. And this fragmented definition of SDN results in fragmented approaches to design,in mixing up the attributes of SDN with those of network virtualization (NFV), and in users not fully understanding the benefits of this technology in terms of cost savings, performance and time-to-market benefits.

Network Virtualization and Software Defined Networking for Cloud Computing: A Survey

CTN Issue: August 2014

Network virtualization is the key to the current and future success of cloud computing. This article covers the key reasons for virtualization, and briefly explains several of the networking technologies that have been developed recently or are being developed in various standards bodies (IEEE, IETF, etc). In particular, the article explains software defined networking(SDN) and why it is the key to network programmability with an illustration called OpenADN which is an application delivery framework in a multi-cloud environment.

Are We Ready for SDN? Implementation Challenges for Software-Defined Networks

CTN Issue: August 2014

Cloud services are exploding, and organizations are converging their data centers in order to take advantage of the predictability, continuity, and quality of service delivered by virtualization technologies. In parallel, energy-efficient and high-security networking is of increasing importance to network operators. Software Defined Networking (SDN) has emerged as an efficient network technology capable of supporting the dynamic nature of future network functions and intelligent applications while lowering operating costs through simplified hardware, software, and management. This article addresses the question of how to achieve a successful carrier grade network with SDN. Specific focus is placed on the challenges of network performance, quality, scalability, security, and interoperability with the proposal of potential solution directions.
