Thanks Barber, and all responders,

Now I really got confused, I found several replies and some tell dependent
(2) while some tell independent (2).

Does it means that if the product spec doesn't mentiuons, we should always
assuming 64 byte packets?

Is it true that the pps is inverse portional to the packet size? (Say 20k
pps @ 64byte will means 853 pps @ 1500 byte packet) Or it's non-linear and
the product doc. should menions about it? (say 20k pps @ 64 byte, but 15k
pps @ 1500 byte)

How about the switches? Does all the above applies? Does fps mentioning
1500 byte frames?

Thanks a lot for your kindness,
BBD (Big Black Dog)

It is not independent. If it doesn't state you should assume 64 Byte
packets.

20k pps or 20k fps should be independent of packet size.

Hi group,

If a router is labelled 20k pps, does it mentioning 64 Byte packets or 1500
Byte packets? Will this pps reduces if packet size becomes larger?

Also, if a switch mentioning 20k fps. does it reference to any length of
frame? Will this fps reduces if frame size becomes larger?

Thx,
