This draft describes extended performance statistics for TCP. They are designed to use TCP's ideal vantage point to diagnose performance problems in both the network and the application. If a network based application is performing poorly, TCP can determine if the bottleneck is in the sender, the receiver or the network itself. If the bottleneck is in the network, TCP can provide specific information about its nature.

The web100 project has implemented TCP kernel instrumentation that approximates this MIB. The web100 instruments are exported via the Linux proc interface (not SNMP), and are differ slightly from this draft. Glen Turner is building a real SNMP agent to access the web100 kernel instruments.
