Forwarding of Control Communication Frames

Function

Bandwidth Limit Function suppresses the Control

Communication Frame data volume to interexchange

among the WAN within the limit of the specified

bandwidth or less.  Data overflow among the WAN

exceeding the contracted bandwidth is prevented.

When the Bandwidth Limit Function is activated, the

Preferential Forwarding of Control communication

Frames Function also becomes activated.  In case

the transmission request to exceed the bandwidth

limit occurs, the control communication frame is

transmitted by giving the priorities based on the below

table.  Even when the WAC Router abandons any data

exceeding the bandwidth limit by its Bandwidth Limit

Function; however, transmission of important control

communication frames can be protected.

 Security function

In addition to the Vnet/IP’s security function, the WAC

Router has the function to destroy packets (such data

as unused protocols and unused port numbers) which

are not used in the WAC Router to reduce vulnerability.

Problems  Cooling water pump equipment

Detecting the signs of cooling water pump failure

in various places in the plant

▲ Cooling water pumps are used in various

places in the plant.

Deterioration of the rotating equipment and

other components that make up the cooling

water pumps can lead to failure of the pumps.

Furthermore, if the cooling water pumps fail

and the cooling water temperature cannot be

maintained, the equipment that needs to be

cooled may also be damaged.
