swfURL Used in the RTMP protocol, this field is used to designate the URL/address of the Adobe Flash Applet being used to generate the stream (if any).
tcURL Used in the RTMP protocol, this field is used to designate the URL/address of the originating stream server.
TOS Type of Service. This is a field in IPv4 packets used by routers to determine how traffic should be dispersed, usually for prioritizing packets.
