  Abstract

In software-defined networking (SDN), the traffic is excessively concentrated on the controller due to the logically centralized architecture. To solve this problem, an orchestration protocol is required to manage multiple domains with multiple SDN controllers. The orchestration protocol is a core technology for topology discovery and fault monitoring as well as end-to-end flow provisioning of multi-domain SDN networks. This paper implements an OpenFlow-based orchestration protocol and evaluates its effectiveness as an orchestration protocol through the experimental results of topology discovery and update. The results show that the traffic generation increases by up to 5.5 times compared to the REST (Representative State Transfer) approach, but reduces it by at least 3.2 times with the implementation of abstraction topology using Dynamic Port Mapping. On the other hand, event processing time can be improved at least 51 times faster than the REST approach. The proposed protocol also has fast monitoring performance at an average rate of 27 ms in various experimental conditions while changing network sizes and topology monitoring periods. In addition, the proposed protocol enables to reuse the open-source controllers and reliable controller-driven topology management.
