    abstract =  {This document defines a new DNS Stateful Operation OPCODE used to communicate operations within persistent stateful sessions, expressed using type-length-value (TLV) syntax, and defines an initial set of TLVs used to manage session timeouts and termination. This mechanism is intended to reduce the overhead of existing "per-packet" signaling mechanisms with "per-message" semantics as well as defining new stateful operations not defined in EDNS(0).},
