F. Harslem +NIC 5820 J. F. Heafner + J. E. White + + + NETWORK ACTIVITY REPORT: UCSB <- -> RAND + +UCSB RJE/RJOR + + The UCSB Remote Job Entry (RJE) and Remote Job Out- put +Retrieval (RJOR) Systems described in NWG/RFC #105 have been used and +validated from Rand. The facility is now being used on a limited +basis as a production tool by another research group at Rand. + Access to the UCSB facility from Rand is through the Network +Service Program (NSP). This program is driven by Rand Video-Graphic +consoles and allows a console user access to both local file storage +(at Rand) and to the Network. A small module (UCSBMGR) was added to +NSP to handle the UCSB RJE and RJOR protocols and data formats. + In exercising the RJE/RJOR facility over the past two months, +typical job sizes included input decks of 800 to 2800 80-character +card images and output files of about 30 pages of printer linstings. + +NETWORK OBSERVATIONS + + In sending files to UCSB we did a timing study over several +transmissions of the above mentioned 2800 record file. On the average +this file was transmitted at a rate of 250 80-character cards per +minute. (Each 80-character card was a separte Network message.) This +is, of course, much less than the advertised 30 kilobit rate; however, +it should be remembered that the path from Rand to UCSB is through at +least one intermediate IMP. On the other hand, the processes at each +end of the connection were running at maximum priority with very small +loads on either machine. An obvious area for speed-up would be the +blocking of card images for network transmission. + In the course of the last two months of networking, we have +noticed approximately five serious failures in transmitted messages. +In two instances, the RFNM on the control link from UCSB to Rand was +lost. Its loss was not reported via a type 9 IMP-to-Host message as +would be expected. We have not been able to cause the problem to +occur; hence we are unable to ascertain whether it is an IMP problem +or a problem with the UCSB Host Interface. + The other three errors were related to the garbling of a data +message between the Rand NSP and UCSB RJE. In all three instances, it +was the second card image trans- ferred to RJE. We were unable to +cause this problem at will; hence have been unable to track it down. +Unfortun- ately the HASP system at USCB merely ignored this image +rather than printing it so we are not aware of the nature nor source + + + + [Page 1] + +of the garbling. It could be anywhere from the disk file storage at +Rand on down the line. This problem was observed sporadically in our +early trans- missions to UCSB and has disappeared. We feel relatively +confident, however, that our Host software on either end was not at +fault. + Lest these last two figures seem too terrifying, it should be +noted that we have run over 100 jobs at UCSB from Rand, each job +consisting of many Network transmissions. + + [ This RFC was put into machine readable form for entry ] + [ into the online RFC archives by Simone Demmel 4/97 ] + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + [Page 2] + |
