Technical Summary

This document defines an EDNS0 option ("edns-tcp-keepalive") that
allows DNS servers to signal a variable idle timeout.  This
signalling facilitates a better balance of UDP and TCP transport
between individual clients and servers, reducing the impact of
problems associated with UDP transport and allowing the state
associated with TCP transport to be managed effectively with minimal
impact on the DNS transaction time.

Working Group Summary

This document originally was adopted but had a few points of controversy 
over the initial size of the keep alive option.  Another draft was 
written at one with a different solution.  The authors ended up 
collaborating on this document and the final solution with input from 
several working group members.
