Hi,
There are actually several questions:
1.a. Is IP_TOS with IPPROTO_IP for the command setsockopt of the winsock2 interface supported for Windows 2012?
Comment : With setsockopt(ConnectSocket, IPPROTO_IP, IP_TOS, (char*)&tosBits, sizeof(tosBits)) initiated in an application, the DSCP value for a sent ip packet could be set on earlier Windows Version (Windows 2003 Server) and Unix etc. I assume that Windows 2012 is also forced to satisfy the winsock2 interface.
1.b. If yes, what do I have to configure on a Windows 2012 Server that the above setsockopt command remains working?
1.c. If no, how does the alternative code snipped look like and what do I have to configure on a Windows 2012 Server that the alternate code is running?
Best Regards
