<div dir="ltr">Hi folks,<div><br></div><div style>We are finally in a position to release the PIE (Proportional Integral controller Enhanced) Linux code.</div><div style>Many of you are already aware of the work at IETF and discussions on PIE on the aqm and bloat mailing lists. Thanks for all the feedback. </div>
<div style><br></div><div style>Documents and code are available over ftp at <a href="ftp://ftpeng.cisco.com/pie">ftp://ftpeng.cisco.com/pie</a></div><div style>The Linux code is available at <a href="ftp://ftpeng.cisco.com/pie/linux_code">ftp://ftpeng.cisco.com/pie/linux_code</a></div>
<div style><br></div><div style>PIE is written as a kernel module and should work with recent kernels. There is also a patch to</div><div style>iproute-3.9 tc tool to configure PIE. README files explain the usage. The complete source files are also available so it should not be too difficult to make it compile on a different iproute2 version.</div>
<div style><br></div><div style>Please check that your basic tests are in sync with what we have seen. Sample results are available at <a href="ftp://ftpeng.cisco.com/pie/linux_code/linux_sampleresults/">ftp://ftpeng.cisco.com/pie/linux_code/linux_sampleresults/</a></div>
<div style>Please let us know if you see any discrepancies.</div><div style><br></div><div style>Thanks in advance for all code reviews. If you have suggestions to improve the code, they are welcome. (Thanks to Eric Dumazet and Dave Taht for Codel codebase). We will also release a version of PIE called Fair-queue-PIE soon (hopefully by the end of the month).</div>
<div style><br></div><div style>If you have any questions, let us know.</div><div style><br></div><div style>Thanks,</div><div style>on behalf of PIE team,</div><div style><br></div><div style>Vijay Subramanian</div><div style>
