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 126.96.36.1991900. 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.
