NETRJT -- Remote Job Service Protocol for TIPS

----------------------------------------------

A. INTRODUCTION

------------

TIP's have very limited processing capability; their function is

mainly limited to interfacing printer-keyboard devices to the Network

using TELNET protocol. It will also be possible to have a tape drive

on a TIP, using a subset of the count form of DTP (see RFC #264).

However, TIP's cannot and will not support either DTP or FTP (see RFC

#265) in general. Therefore, TIP users are excluded from using any

existing remote job entry protocol (e.g. CCN's NETRJS - see RFC #189).

It appears, however, that it may be feasible in the future to use

TIP's for remote job entry in one or more of the following three ways:

(a) Attach local card readers, line printers, and card punches

directly to TIP ports. These devices would use a TELNET-like*

format and frame their characters with Start/Stop bits. BBN

can now supply a suitable 200 LPM printer, and is searching for

suitable readers and punches.

(b) Connect a remote batch terminal to a full-duplex TIP port via

a communication line. BBN is looking into this.

(c) Use the tape drive, and do card-to-tape and/or tape-to-print

on another computer.

BBN hopes to make case (b) look exactly like (a) to the server host.

That is, the remote batch terminal will send to and receive from the

server in a TELNET-like format*; the printer, card reader, punch, and

operator console connections will all use different sockets but one

hardware port at the TIP, which will map multiple sockets into the one

port.

NOTE: By "TELNET-like format", we mean: (a) _CR_LF_ used to delimit

logical records (lines or cards), and (b) the ASCII or EBCDIC

format effector control characters used for carriage control

in the printer stream. It does _not_ necessarily imply ASCII

character codes.

This document describes NETRJT, a modification of CCN's NETRJS

protocol specifically to provide remote job entry service to TIP's

using one of the methods (a), (b), or (c). NETRJT follows the general

model of NETRJS: use TELNET protocol over a primary or "operator"

connection pair, and open simplex secondary connections for data

transfer of job stream input and output. (We also considered the

possibility of using the Divert Output mechanism of the TIP for

sending remote job output over the operator connection, and an

analogous mechanism for input. However, in discussion with Alex

McKenzie, it was agreed that sharing the operato...
