If you want to run some experiments, though, you could look at running PTPd on 3 servers (master, and two slaves) which will get you decent synchronization among the three. Where decent is less than the typical RTT of a TCP packet on a 1Gbps LAN. Best, George On 30 Apr 2015, at 14:48, Karlis

Yes, you are correct, I meant to write "relative OWD". As David Hayes put it - "Relative OWD measurements are easier, and clock drift is not usually a problem over the time it takes to send and receive an ACK". Thank you for the correction! On Thu, Apr 30, 2015 at 4:19 PM, Eggert, Lars wrote: >

Hello, If I will be able to implement the idea described in the publication correctly, I will share the source code. At the moment, though, I am still far away from the implementation, since I have yet to solve the issue of how to get the One Way Delay for the ACK message (the time it takes ACK to

SIFTR and DTrace

2015-04-30 Thread George Neville-Neil
Howdy, I have added support for a DTrace SDT to the SIFTR module in HEAD. What this means is that you can now get SIFTR data filtered out of the kernel directly. I also added a simple script (share/dtrace/siftr) to show how this works. The test script is very wordy and only an example of ho

Are you planning to put the source to this up on a repo (github) or send along patches? It would be good to get a look at this new algorithm. Thanks, George On 21 Apr 2015, at 5:30, Karlis Laivins wrote: Hi, Thank you very much for such a comprehensive description of how to properly create
