Abstract
A network management apparatus comprises: an acquisition unit (21) configured to acquires IP prefix information managed in each of one or more subnetworks in a first network as routing information; an aggregation unit (22) configured to generate aggregated IP prefix information which is an aggregation of the IP prefix information managed in each of the one or more subnetworks as aggregated routing information; and an advertising unit (23) configured to advertise the route information and the aggregated routing information to a second network different from the first network.
Claims10
A network management apparatus comprising:
- at least one memory configured to store program code;
- and
- electric circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code to:
- acquire IP prefix information managed in each of one or more subnetworks in a first network as routing information;
- generate aggregated IP prefix information which is an aggregation of the IP prefix information managed in each of the one or more subnetworks as aggregated routing information;
- and
- advertise the route information and the aggregated routing information to a second network different from the first network.
A network management apparatus comprising:
- at least one memory configured to store program code;
- and
- electric circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code to:
- receive a packet from a terminal apparatus in a first network that is destined for another terminal apparatus in a second network different from the first network;
- acquire routing information and aggregated routing information advertised from each of a plurality of network apparatus in the second network;
- determine a destination apparatus for the packet in the second network based on the route information and the aggregate route information;
- and
- forward the packet to the determined destination apparatus, wherein
- the routing information is IP prefix information managed in each of one or more subnetworks in the second network, and
- the aggregated routing information is aggregated IP prefix information which is an aggregation of the IP prefix information managed in each of the one or more subnetworks.
A network management method comprising:
- acquiring IP prefix information managed in each of one or more subnetworks in a first network as routing information;
- generating aggregated IP prefix information which is an aggregation of the IP prefix information managed in each of the one or more subnetworks as aggregated routing information;
- and
- advertising the route information and the aggregated routing information to a second network different from the first network.
A network management method comprising:
- receiving a packet from a terminal apparatus in a first network that is destined for another terminal apparatus in a second network different from the first network;
- acquiring routing information and aggregated routing information advertised from each of a plurality of network apparatus in the second network;
- determining a destination apparatus for the packet in the second network based on the route information and the aggregate route information;
- and
- forwarding the packets to the determined destination apparatus, wherein
- the routing information is IP prefix information managed in each of one or more subnetworks in the second network, and
- the aggregated routing information is aggregated IP prefix information which is an aggregation of the IP prefix information managed in each of the one or more subnetworks.
A storage medium storing a control program for causing a computer to execute network management processing, the program causing the computer to execute processing, comprising:
- an acquiring process for acquiring IP prefix information managed in each of one or more subnetworks in a first network as routing information;
- an aggregating process for generating aggregated IP prefix information which is an aggregation of the IP prefix information managed in each of the one or more subnetworks as aggregated routing information;
- and
- an advertising process for advertising the route information and the aggregated routing information to a second network different from the first network.
