From a42e9d6ce89cfd19aee9f990b7231ce697f0d00f Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Mon, 5 Jun 2006 17:30:32 -0700 Subject: [TCP]: TCP Probe congestion window tracing This adds a new module for tracking TCP state variables non-intrusively using kprobes. It has a simple /proc interface that outputs one line for each packet received. A sample usage is to collect congestion window and ssthresh over time graphs.
