I can answer the second part.
yes, ifOutOctets is pretty much the same things as bytes/second. However,
since it is stored in memory as a counter (usually a 32 bit unsigned
integer value), the raw values would mean nothing. So, typically it is used
to display bytes/sec over a link by subtracting a previous value and
dividing by the polling interval.
