            Experimental Option for TCP Host Identification
                 draft-williams-exp-tcp-host-id-opt-05

Abstract

   Recent IETF proposals have identified benefits to more distinctly
   identifying the hosts that are hidden behind a shared address/prefix
   sharing device or application-layer proxy.  Analysis indicates that
   the use of a TCP option for this purpose can be successfully applied
   to a broad range of use cases.  This document describes a common
   experimental TCP option format for host identification.
