A Revised Internet-Draft is available from the on-line Internet-Drafts 
directories. This draft is a work item of the TCP/UDP Over CLNP-Addressed 
Networks Working Group of the IETF.                                        

       Title     : CLNP Path MTU Discovery                                 
       Author(s) : D. Piscitello
       Filename  : draft-ietf-tuba-mtu-01.txt
       Pages     : 17
       Date      : 06/03/1994

This memo describes a technique for dynamically discovering the maximum 
transmission unit (MTU) of an arbitrary CLNP path. The mechanism described 
here is applicable to both "pure-stack" OSI as well as TUBA/CLNP 
environments, i.e., environments where Internet transport protocols (UDP 
and TCP) are operated over CLNP. This technique might not in all cases 
discover the optimum Path MTU, but it will always choose a Path MTU as 
accurate as, and in many cases more accurate than, the Path MTU that would 
be chosen by current practice.
