RITA -- The Reliable Internetwork Troubleshooting Agent

RFC 2321                          RITA                      1 April 1998


   In this document we introduce a new hardware-based tool for diagnosis
   and repair of network related hardware and software problems. This
   tool is best suited to addressing nondeterministic problems such as
   those described above. This tool has broad areas of application at
   all levels of the OSI model; in addition to uses in the physical,
   network, transport and application layers, it has been used to
   successfully address problems at the political and religious layers
   as well. RITA, the Reliable Internet Troubleshooting Agent, was
   developed initially at The Leftbank Operation (now known as Cohesive
   Network Systems, New England Division) based on a hardware platform
   supplied by Archie McPhee (Reference [1]). A typical RITA unit is
   depicted in Figure 1.
