TCP Measurement Instrumentation

There are several mechanisms that can be used to observe performance of TCP in a system. In particular, on Linux there are:

• TCP_INFO
• Web10G's Kernel Instrumentation Set (KIS)
• The "TCP Tracer"

Of these, only TCP_INFO is supported by "mainline" Linux as of December 2014. There are plans for a meeting in early 2015 to discuss requirements for TCP instrumentation. Interested parties include engineers from Google, Facebook, Akamai, and the Web10G project.

Systems such as DTrace may be useful on other types of operating system.
