Abstract

Disclosed is a procedure for passing network traffic through a series of low-cost workstations attempting to locate one that may be connected to a network in order to forward a problem notification message to a network operator. The name of the procedure is called the Network Notification Through Non-Standard LANs (NNTNSL).

Network Notification Through Non-Standard LANS

      Disclosed is a procedure for passing network traffic through a
series of low-cost workstations attempting to locate one that may be
connected to a network in order to forward a problem notification
message to a network operator.  The name of the procedure is called
the Network Notification Through Non-Standard LANs (NNTNSL).

      First Failure Support Technology* (FFST), a software service
package, processes error events and generates a number of diagnostic
data outputs.  One of these outputs is a network notification to
alert a network operator that a problem has occurred in a
workstation.  In an environment where the workstation may not have
network access, getting this notification to a network operator is a
problem.  This situation often exists where a series of low cost
workstations are utilized and their function does not require
communications through a network.  Often in this situation though,
there is one workstation that is attached to a LAN while the others
are free-standing.  If FFST is called in this environment to process
an error condition, there is no way to send the notification to a
network operator if the error was detected on one of these machines
not attached to a network.  In order to solve this problem, NNTNSL
was developed.

      NNTNSL is a procedure by which a very small application module,
known as the NNTNSL Router, is placed in each workstation including
the workstation that is attached to the network.  Each workstation is
daisy-chained together through the communications port using serial
port connectors.  The Router component uses basic read/write commands
to receive and send data through the chain of workstations in an
attempt to locate a workstation attached to the host.  If the Router
receives a network notification data flow and the workstation is not
network attached, the Router passes the flow on to the next-in-chain
workstation.  If the Router receives the data packet and it is
network attached, the network software services on the workstation
are used to place the notification int...
