Subject: Request on information on HYPERchannel

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"

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.
