[Xen-devel] Re: [PATCH 0/2] dm-band: The I/O bandwidth controller: Overview



Hi Peter,

The bandwidth in dm-band is determined by the proportion of the
processing time of each device's tokens(I/Os) to the processing time
of all device's tokens(I/Os).
The processing time of one token(I/O) is determined by one I/O cycle 
include seek latency, interrupt latency, etc...

Thanks,
