TCP Problems with Path MTU Discovery

RFC 2923          TCP Problems with Path MTU Discovery    September 2000


   Classification
      One or more problem categories for which the problem is
      classified:  "congestion control", "performance", "reliability",
      "non-interoperation -- connectivity failure".

   Description
      A definition of the problem, succinct but including necessary
      background material.

   Significance
      A brief summary of the sorts of environments for which the problem
      is significant.

   Implications
      Why the problem is viewed as a problem.

   Relevant RFCs
      The RFCs defining the TCP specification with which the problem
      conflicts.  These RFCs often qualify behavior using terms such as
      MUST, SHOULD, MAY, and others written capitalized.  See RFC 2119
      for the exact interpretation of these terms.

   Trace file demonstrating the problem
      One or more ASCII trace files demonstrating the problem, if
      applicable.

   Trace file demonstrating correct behavior
      One or more examples of how correct behavior appears in a trace,
      if applicable.

   References
      References that further discuss the problem.

   How to detect
      How to test an implementation to see if it exhibits the problem.
      This discussion may include difficulties and subtleties associated
      with causing the problem to manifest itself, and with interpreting
      traces to detect the presence of the problem (if applicable).

   How to fix
      For known causes of the problem, how to correct the
      implementation.
