I wonder how you think the suggested scheme for IPoIB plugs into the existing QoS flow at the Linux network stack. Looking on the man pages of tcp(7) and ip(7) I see that there's a SOL_SOCKET level option of SO_PRIORITY and SOL_IP level option of IP_TOS.
Giving this a little more thought, IPoIB uses a single path to each IP destination. You're asking about per socket ToS, which requires the ability to handle multiple paths to each remote IP address. Both the original RFC and my proposal for the host stack limit all IPoIB traffic to a single QoS level.
Is there a real need to expand IPoIB ToS capabilities? - Sean _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
