Experimental Implementation[edit]

In this page work are released experimental linux kernel patches which should become officially included in the official kernel tree later.

Patch for linux 2.6.16.18 kernels[edit]

Download: tcp_westwood_2.6.16.18_fixes.patch

The patch applies to 2.6.16 kernels and it has been tested in 2.6.15 kernels too. This patch fixes a bug in the first bandwidth estimation and adds some feature and improvements:

• RTT_min is now updated each time a timeout event occurs (in order to cope with hard handovers in wireless scenarios)
• The bandwidth estimate filter is now initialized with the first bandwidth sample in order to have better performances in the case of small file transfers.

Download: web100_tcp_westwood_2_6_16.patch

Applies to 2.6.16 kernels patched with the 2.5.10 release of web100. This patch enables logging the End to End estimated bandwidth using web100.
