This paper proposes the Hybrid Domain Discovery Protocol (HDDP), a new lightweight discovery protocol that outperforms the existing OpenFlow Discovery Protocol (OFDP). HDDP allows the discovery of hybrid network topologies composed of both SDN and non-SDN devices
In this paper, we present the Tree Exploration Discovery Protocol (TEDP), proving that shortest paths can be built at the same time that the topology information is gathered, without extra messages compared to LLDP.
