A couple of years ago I was attending the IETF-OSI Working Group chaired
by Rob Hagens and helped to define an Echo function for CLNP (ISO 8473).
This work eventually became RFC1139, "An Echo Function for ISO 8473".

This RFC lists two possible methods to implement an Echo function which
would be suitable for "ping" type functionality for ISO. The first was
an interim solution requiring special N-Sel values in the NSAP. The second
was a more robust solution which essentially expands the ISO 8473 spec to
include Echo NPDUs. 

As I recall, someone at the Working Group session agreed to propose this
to ANSI X3S3.3, and eventually/hopefully to ISO as well for inclusion in
a future version of 8473.

I have two questions:

	1) Can anybody update be as to the status of getting an Echo 
	   function added ISO 8473?

        2) Has anybody incorporated RFC1139 into their OSI protocol
	   suite? if so which solution?

Thanx in advance
