Hybrid NDP Proxy in OpenFlow Network
Daftar Isi:
- The implementation of Neighbor Discovery Protocol (NDP) in OpenFlow network was handled specifically by three different methods including the learning switch, reactive proxy, and proactive mechanism. All of the specified approaches still raised problems either consuming the controller’s resources or forcing manual adjustment by the network administrator. This paper combined both reactive and proactive manner by deploying an application called Hybrid NDP proxy (HNDPP). The controller stored all information from Neighbor Solicitation (NS) request for generating OFPT_FLOW_MOD message as the guideline for the OpenFlow switch to response and craft the Neighbor Advertisement (NA) based on the defined selector and treatment. The research’s results showed the effectiveness of the HNDPP by reducing the number of NS requests that entering the controller up to 20 packets on average. In addition, the waiting time for receiving NA packet lessened approximately below 0.5 ms.
