Network Working Group R. T. Braden Request for Comments: 189 UCLA/CCN Obsoletes: RFC 88 (NIC 5668) 15 July 1971 NIC 7133 Category: D


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It is anticipated that the interim protocol will be superseded in a few months by a revised NETRJS, but the changes will be minor.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.

(2) A "transparency" mode for input from ASCII remote sites, to allow the transmission of "binary decks" (object decks) in the job stream from these sites.

(3) More than one simultaneous virtual card read, printer, and punch stream to the same virtual terminal.

Comments on the utility of these proposals or others for your site would be appreciated.

(Interim Protocol)

A. Introduction

NETRJS is the protocol for the remote job entry service to the 360 Model 91 at the UCLA Campus Computing Network (CCN). NETRJS allows the user at a remote host to access CCN’s RJS ("Remote Job Service") sub-system, which provides remote job entry service to real remote batch (card reader/line printer) terminals over direct communications lines as well as to the ARPA Network.

To use NETRJS, a user at a remote host needs a NETRJS user process to communicate with one of the NETRJS server processes at CCN. Each active NETRJS user process appears to RJS as a separate (virtual) remote batch terminal; we will refer to it as a VRBT.
