Re: Ntop Digest, Vol 65, Issue 12

Hi All.
Thank you all for the fast reply.
The micro bursts I'm dealing with are very interesting. for example.
I have a leased line of 10Mb from point to point and my application uses udp to send data. the application running on a server with 1Gb interface.
The application sends on the average 1000Kbs when I'm looking in one minute average but If I will draw a graph using wireshark I'm able to see that during a fraction of a milliseconds the application sends 40 Kbps while the maximum of 10 Kbps is allowed per millisecond.(10Mbps=10240Kbps/1000 = 10.24K per millisecond.)
my application is very latency affected.
I have two options to deal with the problem above.
1. I can set the nic on the server to 10Mb and the operating system will throttle the data, But I wish to copy files locally from that server as well.
2. Throttling the data somehow on the application layer.
But I need to know that I'm suffering from this problem and in my case I have dozen of the same application running I can't spend all day wiresharking and filtering the data with 12 different filters.
Many Thanks
Dudu.
