Simple Service Discovery Protocol (SSDP)
The SSDP protocol can discover Plug & Play devices, with uPnP (Universal Plug and Play). SSDP uses unicast and multicast adress (18.104.22.168). SSDP is HTTP like protocol and work with NOTIFY and M-SEARCH methods.
SSDP can be used over IPv4 and IPv6.
- SSDP uses UDP transport protocol on port 1900
The SSDP dissector is partially functional : there is no ssdp filter, but, the http filter show HTTP and SSDP protocols. The solution is to filter with the destination port (see Display filter). Bug 6190 requests that this behavior be changed.
SSDP has no preference setting.
