Openflow discovery protocol
Webdiscovery in OpenFlow-based networks and in hybrid net-works composed of traditional and OpenFlow switches (OF switches), which to our knowledge has not been addressed before. Furthermore, this work does a specific study of Layer 2 protocols that perform topology discovery in OpenFlow-based networks. Basically, we present to the best of … WebThe SDN controller uses the OpenFlow Discovery Protocol (OFDP) to collect network topology status. OFDP detects the link between OpenFlow switches by generating Link Layer Discovery Protocol (LLDP) packets.
