Abstract

Described is a common problem with providing support in the data communications environment is the wide range of heterogeneous networks used by the customers. Customers report problems to a support group which is singular to their unique networking environment. This networking environments may have specific and multiple hosts, bridges, routers, and host applications. Therefore, it is often impossible for the support group to recreate these network environments for further analysis the customer's problem.

Network Data Simulator

      Described is a common problem with providing support in the
data communications environment is the wide range of heterogeneous
networks used by the customers.  Customers report problems to a
support group which is singular to their unique networking
environment.  This networking environments may have specific and
multiple hosts, bridges, routers, and host applications.  Therefore,
it is often impossible for the support group to recreate these
network environments for further analysis the customer's problem.

      Network Data Simulators (NDS) uses two widely available
networking tools: line or traffic recorders, and data communications
traffic generators.

      Line or traffic recorders record verbatim the data received
and/or send on a communication media such as ethernet, tokenring,
RS232, et cetera.  This record is currently used for human analysis.
The IBM RS/6000* has a built in trace recorder for its SNA traffic.

      Traffic generators are a tool which can be programmed to
simulate a particular data traffic sequence.  These generators use a
simple or low level programming language, which basically requests
that a specified bit sequence is sent.  For example, "SEND
/2C00020100024B8000C8/;" .

      The NDS is a filter and a code generator which takes as input
the recorded data traffic and produces a program framework which can
be run on the traffic generator.  The program will accurately
recreate a recorded network scenario from the AIX RS/6000 SNA trace
facility.  The created program can then be used to generate network
traffic and test the response.  This allows the traffic from a...
