Abstract
A desired static route is read from a static routing table and a polling is effected on a network connected to a terminal at regular intervals. If a normal response is issued from the network, then information about the above static route is entered in a routing table. If no normal response is delivered from the network, then the information about the static routes entered in the routing table is deleted.
Claims3
A static routing system comprising:
- a routing table operated for effecting routing to other device connected to a local-area network;
- an application program for polling said local-area network;
- a static routing table in which are entered static routes including an address for a network to be routed, and a time interval required to perform polling;
- a timer;
- and
- controlling means for reading a desired static route from said static routing table and starting said application program so as to poll a corresponding network each time a lapse of a predetermined time is reported from said timer, entering said static route in said routing table when a normal response is sent back from said network and deleting said static route from said routing table when the normal response is undelivered from said network.
