INTERIM NETRJS SPECIFICATIONS
The following document describes the operation and protocol of the
remote job entry service to CCN's 360 Model 91. The interim protocol
described here will be implemented as a production service before the
end of July. Two host sites (Rand and UCLA/NMC) have written user
processes for the interim NETRJS, based on the attached document.
Questions on it should be addressed to CCN's Technical Liaison.
It is anticipated that the interim protocol will be superseded in a
few months by a revised NETRJS, but the changes will be minor. The
revision will bring the data transfer protocol of NETRJS into
complete conformity with the proposed Data Transfer Protocol DTP (see
RFC #171). The present differences between the DTP and NETRJS
protocols are:
(a) The format (but not the contents) of the 72 bit transaction
header of NETRJS must be changed to conform with DTP.
(b) The End-of-Data marker must be changed from X'FE' to X'B40F'.
(c) The initial "modes available" transaction of DTP must be
added.
(d) Some of the DTP error codes will be implemented.
No other protocol changes are presently planned, although some may be
suggested by operating experience with the interim protocol. When
the revised protocol has been fully specified, it will be implemented
with different ICP sockets than the interim protocol. This will
allow a site which wants to start using CCN immediately to convert
his protocol at leisure.
Some possible future extensions to NETRJS which have been suggested
are:
(1) A 7-bit ASCII option of data transfer connections, for the
convenience of PDP-10s.
