Abstract:

Software defined networking (SDN) has been applied increasingly in practical networks. Currently, SDN is mainly used to improve the flexibility and efficiency of datacenter networks, enterprise networks and wide-area networks (WAN). There also emerge some studies that try to deploy SDN to inter-domain settings. In this article, we introduce the progress stages of inter-domain SDN and studies related to each stage. Finally, we discuss the applications and challenges of inter-domain SDN.

Key words: software defined networking, network programmability, inter-domain SDN
