[comp.protocols.iso] $#!@ Concatenation

pae@athena.mit.edu (Philip Earnhardt) (07/06/90)

Section 6.3.7 of ISO 8327 says that category 2 SPDUs are never mapped
one-to-one onto a TSDU. What exactly does this mean--do I *always*
have to use concatenation to send out a Data Transfer SPDU? I'm
implementing the Kernel functional unit; it seems decidedly silly to
be sending a Give Tokens SPDU, since there aren't any tokens on our
S-connection.

On a related theme, could someone explain why Give Tokens is listed as
mandatory in the ISPICS Requirements List for the FTAM International
Standardized Profiles AFTnn draft standard (ISO/IEC DISP 10607-1: 1990(E)).

Thanks.
