Multi-Domain Federation Utilizing Software Defined Networking—A Review
Mohammad Hassan, Mark Gregory, Shuo Li
Abstract
The global growth of the Internet continues with an increase in accessibility, connected users and new applications in emerging fields like egames, augmented and virtual reality. Technologies that improve reliability whilst reducing cost and latency are being developed. However, before the Internet can sustain the growth in utilisation and new applications there are challenges to overcome. One of the key challenges remaining is to develop new mechanisms for intra and inter-domain federation that facilitate fast, reliable, and secure sharing of reachability and routing information. Software Defined Networking (SDN) is being introduced to address control and management challenges at domain boundaries. This paper reviews the current state of domain federation and discusses the potential approaches that utilise SDN for a next-generation solution.
