Essentially they are what they say.  'Sustained data rate' reflects more
or less the average data rate over a period of time.  Different systems
compute it slightly differently (different average periods) but it's
essentially what you can expect to be the supported average amount of data
going through at any given time.  This would be when the cache is full and
active, when all buffers are loaded, etc.

'Burst transfer rate' is the highest rate you can expect data to travel
through the connection at any given time.  For example, there may be a
burst of data to begin a communications, but then it evens out to the
'sustained' rate.

Many thanks!

Hi,
What do "sustained data rate" and "burst transfer rate" mean? I appreciate
your explanation or any reference.

Thanks
