New commer questions

[Tom-PT Taylor]

We use the RFC 1006 length specifier to indicate total message length in
TCP.

The "ALF" is actually anything but message delimitation -- not sure how it
got that name.  The functions performed by the application are
 -- reliable delivery (aided by Megaco's transaction orientation)
 -- sequencing (not much needed in Megaco except in sorting out event
reports)
 -- throttling in the face of network congestion.
