With WS-Discovery, the discovery tool puts SSDP queries on the network from its unicast address to 184.108.40.206 multicast address, sending them to the well-known UDP port 3702. The device receives the query, and answers to the discovery tool's unicast IP address from its unicast IP address.
Mar 30, 2016 · Guaranteed communication over TCP port 3702 is the main difference between TCP and UDP. UDP port 3702 would not have guaranteed communication as TCP.
