Abstract

The complexity of today's local area networks is such that they must be monitored frequently to determine if there are any problems and to check general network utilization and performance indicators. If an institution has more than one network segment, it may also need more than one network monitor. As the number of network segments increases, the expense incurred on network monitors becomes unreasonably large. Thus, if just one network monitor could be used to probe all the network segments, savings could be considerable. Since manual switching of a single monitor between multiple network segments is not a practical solution, we shall in the following propose an automated solution to the problem.

Switchable Network Connection Unit

   The complexity of today's local area networks is such that they
must be monitored frequently to determine if there are any problems
and to check general network utilization and performance indicators.
If an institution has more than one network segment, it may also need
more than one network monitor.  As the number of network segments
increases, the expense incurred on network monitors becomes
unreasonably large.  Thus, if just one network monitor could be used
to probe all the network segments, savings could be considerable.
Since manual switching of a single monitor between multiple network
segments is not a practical solution, we shall in the following
propose an automated solution to the problem.

      As shown in Fig. 1, in order to operate the SNCU, a control PC,
a control PC, a network device (such as a network monitor), and a
network segment (such as token-rink segment) are needed.  In the
example, network segment #3 has been selected, i.e., the relay has
been activated.

      Disclosed is a local area network component, the Switchable
Network Connection Unit (SNCU), which will enable any network capable
workstation, including a network monitoring device, connected to the
SNCU to be inserted into any one of eight network segments connected
to the SNCU as illustrated in Fig. 1.  The selection of a particular
network segment is performed by remote personal computer (PC) control
of a switching device inside the SNCU.  When one of the eight outputs
of the switch is activated the output subsequently triggers a
mechanical relay which then establishes a connection between the
monitoring device and a network segment (in this case #3 in Fig. 1
where the relay has been activated).  Only one network segment can be
selected at a time.  The figure also in...
