ROUTING CONTROL METHOD AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM STORING ROUTING CONTROL PROGRAM
First Claim
1. A routing control method in a network in which a plurality of communication terminals and at least one server are connected through at least one router, the method comprising:
- receiving, by a network controller, an event which changes a destination address of the at least one server, the network controller being configured to control the network and having routing information of the at least one router in the network and a function to control the routing information of the at least one router in the network;
in response to receiving the event, primarily controlling, by the network controller, routing information which does not affect a communication being connected; and
after processing of changing the destination address has been completed, controlling, by the network controller, routing information which affects the communication being connected.

Abstract
In a network in which a plurality of communication terminals and at least one server are connected through at least one router, when a network controller, configured to control the network and having a control function of routing of the at least one router in the network and routing information of the at least one router the network, receives an event which changes a destination address of the at least one server, the network controller primarily controls routing information which does not affect a communication being connected and after the processing of changing the destination address has been completed, controls routing information which affects a communication during connecting.

6. A non-transitory computer-readable recording medium storing a routing control program for causing a computer to execute:
-
being executed by a device, causing the device to perform a routing control in a network in which a plurality of communication terminal and at least one server are connected through at least one router, the device having routing information of the at least one router in the network and a function to set and monitor the routing information of the at least one router in the network; receiving an event which changes a destination address of the at least one server; primarily controlling routing information which does not affect a communication being connected; and after processing of changing the destination address has been completed, controlling routing information which affects the communication being connected. - View Dependent Claims (7)

8. A non-transitory computer-readable recording medium storing a routing control program for causing a computer to execute:
-
being executed by a device, causing the device to perform a routing control in a network in which a plurality of communication terminal and at least one server are connected through at least one router, the device having routing information of the at least one router in the network and a function to set and monitor the routing information of the at least one router in the network; receiving an event which changes a destination address of the at least one server; primarily controlling routing information of a downstream route which does not affect a communication being connected; setting, to routing information of an upstream route, the routing information in which the destination address has been changed such that the routing information is not received; and after processing of changing the destination address has been completed, controlling a state capable of receiving the routing information, in which the destination address has been changed, of the upstream route.
