Kai Gao, Changqiao Xu, Jianfeng Guan, Yang Liu · 2017
The idea of decoupling the control and forwarding and programmable network has been concerned by the researchers due to the emergence of software defined network which acts as the future network. Also, terminals equipped with multiple interfaces are increasing which can use multiple paths simultaneously. Multipath transport mechanism can improve throughput via multiple paths. We present a survey about multipath transport mechanisms in software defined network. First of all, the research on single TCP in SDN is analyzed. Then, SDN-based data center, the path management and the SDN testbed of multipath transport mechanism are summarized respectively. Finally, the developments and challenges of multipath transport mechanism in software defined network are put forward.
