  • Thread-topic: Limiting Domains' Network Network Transmit Rate


I was wondering if it is possible to limit the rate of packet
transmission for individual domains.  The "Safe Hardware Access..."
paper mention's a credit based scheduler for network transmission, which
would seem to be perfect for what I need, however in the Xen netback
driver source code, the credit code seems to be taken out by the
pre-processor (with a "#if 0").

Would this credit code work if I put it back in, and if so, how can the
credit for each vif be set?  If this would not work is there any other
way of limiting the network transmission of individual domains?

Thanks for your help
