Hi,

I'm not really sure of what you need, but I don't think LOAD will do that. According
to the code, it works only for Relative Time elements -which is probably what it is
asking from you-, and seems to be something of the like of "amount of time this 
represents in relation to the absolute time".

Wouldn't bytes/sec do? I mean, if you do a filter for protocol 1 and ask bytes/sec on it, 
and then probably divide by the interface speed -which ethereal does not really know,
so it cannot do it by itself- isn't that what you need?

If what you need is, on the other hand, the network load of protocol 1 against the total
traffic, then you might be able to do it with statistics generated by tethereal, which
will give you a table you can them import in a worksheet and divide period by period.

Regards,
