Re: [Ethereal-users] Packet Loss

[fonte fonte <fonte_monte@xxxxxxxxx>]

Hi,
  
  Thanks for the answer. I get what you mean. So how do I get total data  packet that are lost? Is there a sort of guideline on acceptable or  normal data packet loss on every network (and I'm especially interested  in GPRS network) whereby these losses don't really have a significant  impact on network performance?
  
  Thanks.
