A Survey on Multicasting in Software-Defined Networking
Salekul Islam, Nasif Muslim, John William Atwood · IEEE Communications Surveys & Tutorials · 2017
Existing surveys of research into software-defined networking (SDN) make only minimal mention of multicasting. We present a survey of existing multicast routing protocols in Internet Protocol (IP) multicast, and a survey of existing and proposed multicast routing algorithms in SDN multicast. Each of these protocols/algorithms is designed to optimize a slightly different metric, under specific constraints, so we contrast the approaches based on the optimization goal. We then present a survey of existing and proposed approaches to security for IP multicast and SDN multicast. This reveals a striking lack of breadth in the research in the topic of SDN multicast security.
