minissdpd

UPnP IGD discovery speed enhancer

Every UPnP device and UPnP client (or control point in UPnP terminology) needs to listen to SSDP packets broadcasted to the group 239.255.255.250:1900. When several UPnP devices are running on the same server, or several UPnP control points are trying a discovery process on the same server, there is concurence to open a bind a socket on the UDP port 1900. MiniSSDPd can also provide a history of the SSDP NOTIFY packets sent on the network during a period of a few minutes and it keeps track of all UPnP devices that announced themselves on the network through SSDP NOTIFY packets.
