It was suggested that I send our message to you by Dale Chase <chase@venera.isi.arpa>. Your help would be greatly appreciated. -- Tim J. Hern Begin forwarded message Received: By E.ISI.EDU via direct-append with Hermes; 26 Feb 87 15:14:15-CST Date: 26 Feb 1987 15:14-CST From: SAC.AFGWC-SDMC@E.ISI.EDU To: ACTION@A.ISI.EDU Cc: SAC.AFGWC-SDMC@E.ISI.EDU Subject: Request on information on HYPERchannel Message-ID: <[E.ISI.EDU]26-Feb-87 15:14:14.SAC.AFGWC-SDMC> Sender: SAC.AFGWC-SDMC@E.ISI.EDU 1. We are looking for users, special interest groups or vendors that have information on techniques/products that can be used to monitor our Network Systems Corporation (NSC) HYPERchannel, a high speed, radio-frequency, cable-based broadcast computer network. We are looking for software/hardware to: - Monitor the frequency of specific data transfers from host to host. In other words, "what is going where." - Monitor network throughput. - Get information on host-to-host transmission delays. - Get information on how long data is in queue before it is transmitted. - Monitor the size of the data being transferred. - Monitor the loading on the source computer and receiving computer during the transmission of the data. - Monitor the amount of CPU resources the actual transmission takes. - Track the shipment of data between two database machines (specifically Sperrys). 2. Our HYPERchannel allows the following communication configurations: Intra Sperry, intra VAX, Sperry to/from Vax and Sperry to/from Cray. We have the following kinds of computers: - Sperry 1100/82s. - Sperry 1100/72s. - Sperry 1100/91s. - DEC VAX 11/780s. - A Cray X-MP. 3. We wrote the communication software residing on the Sperry 1100s. Vendors wrote the communication software residing on the Vax computers and Cray. The following chart shows which communication software we have written and which software vendors have written: "AUTHOR OF COMMUNICATION SOFTWARE" "USAF" "USAF" "Harris" "Harris" "Sperry" "Sperry" ---------------------------------------------------------------------- | 1100s <--> 1100s HOST | | 1100s <------------> Vax COMPUTER| | Vax <------> Vax | | 1100s <---> Cray 4. We need information on the following subjects: - User written communication software which can be used on HYPERchannel. - We would like users to send us their evaluations of their HYPERchannel communication software, i.e., its advantages and disadvantages and whether the users are satisfied with it. - Network monitoring software/techniques, such as NSC's Network Recording Facility, which will be available in mid 1987. This software will show data flow on a network. It is a "passive" system which receives records from other systems on the network. - Commercial communication monitoring software, such as NSC's Network Monitor software, as well as user created software, which monitors the "health" of the NSC hardware.

Does Network Systems Corp have any aswers to your questions? Vint

MITRE is seeking a product to support remote access by 1 to 16 terminals to an Ethernet LAN and through the LAN to a VAX host running VAX/VMS. The protocols to be supported include TELNET/FTP, TCP, and IP, with terminal rates of 1200 to 9600 bps. Need basic technical data and POC for follow-up. Understand the Communications Machinery Corporation (CMC) has a suitable device, the CMC serial bridge terminal server; this option is being investigated presently. Are there users of this device out there in the ether who can advise of its reliability, performance, and general overall goodness? MITRE POC Andrew K.
