ACK packets?

ACK packets?

Hi I was wondering if anyone knew roughly how much Upstream bandwidth is used for ACK packets when downloading at around 240Kb/s?

every packet u get needs to send an ACK back, however they are like 1K in size or less so its not a "bandwidth sucking" issue, however if you are finding that your upload kills ur download speed (as i do.. grrr) you need to set some rules up on ur firewall / router to allow ACK packets priority over all other packets and that way you wont get the eating of dl speed

the router I use doesnt allow for that atm, so I was planning on working out exactly how much bandwidth I need to reserver on my lan for ack packets.

A rule of thumb is to reserve about 5KB/s for a fully utilised 512Kb line. For for a 2Mb line, it wil suck over half the upstream available.

Also remember, the fact you are reserving upstream sugest you do want to upload. So you should reserve downstream too.

Failure too will make your spoeed go haywire.
