The PeSIT protocol is the result of efforts
by the banking profession, in the framework of GSIT, to field a
file transfer system.
Connecting the data centres of member banks to
the network stations required a file transfer protocol able to meet
two essential requirements :
- integrate within the ISO/OSI model, potentially
on very disparate hardware,
- operate flexibly as regards communication media
(specialised links, public networks, local area networks etc.).
The ISO file transfer protocol, FTAM, could have met these requirements
had its production process been sufficiently rapid to guarantee
that the banking community would have access to FTAM products at
a date compatible with the SIT project schedule. Since this was
not the case, the banking profession therefore decided in
1985 to define a file transfer protocol for connecting to the SIT
network. The result is PeSIT. This protocol is based on
the same philosophy as FTAM (integration in the ISO model, virtual
file model etc.), and the PeSIT service (interface with the protocol
user) is identical to the FTAM service. However, PeSIT offers only
a subset of the planned functions of FTAM.
