Abstract

A communication network structure, in particular data communication network structure, includes a plurality of autonomous communication networks. Each autonomous communication network has at least one network node. The node is connected to a common gateway. The common gateway is designed to selectively connect at least two of the nodes in order to provide intercommunication ability between the related communication networks. A method of interconnecting autonomous communication networks includes: selecting networks or network nodes to be interconnected from a list of available networks or network nodes or selecting a preset configuration of inter-node connections; activating an interconnection between the selected networks or network nodes by creating an access-list using the IP-addresses defined for each node; and applying the access-list on a router element provided in said gateway, thus connecting the nodes/networks to each other.

First claim

What is claimed is:

1. A data communication network structure, comprising:
a plurality of physically autonomous data communication networks, including a first autonomous data communication network comprising a first network node, a second autonomous data communication network comprising a second network node, and a third autonomous data communication network comprising a third network node,
wherein the first network node, the second network node, and the third network node are connected to a common gateway;
wherein the first network node controls said common gateway to selectively connect the second network node with the third network node;
wherein said common gateway is configured to have a plurality of predefined and preset configurations of inter-node connections and to allow a user of the first network node to directly select and activate a preset configuration from said plurality of predefined and preset configurations; and
wherein the common gateway is activated only during a crisis, and the common gateway is deactivated when there is no crisis, such that there are no connections between the network nodes when the common gateway is deactivated.

2. The data communication network structure according to claim 1 , wherein said common gateway is configured to allow a user to individually select and interconnect two or more network nodes from said plurality of autonomous data communication networks.

3. The data communication network structure according to claim 2 , wherein said common gateway comprises at least one router element to which said nodes of said autonomous data communication networks are selectively connected.

4. The data communication network structure according to claim 1 , wherein said common gateway is configured to allow a user to individually select and interconnect two or more network nodes from said plurality of autonomous data communication networks.

5. The data communication network structure according to claim 1 , wherein said common gateway comprises at least one router element to which the first, second and third network nodes of said autonomous data communication networks are selectively connected.

6. The data communication network structure according to claim 1 , wherein the first network node is configured to disconnect the second autonomous data communication network from all access to the data communication network structure.

7. The data communication network structure according to claim 1 , wherein the first network node is configured to selectively disconnect network nodes of the second autonomous data communication network from the data communication network structure.

8. The data communication network structure according to claim 1 , wherein the first network node controls said common gateway to selectively connect the second network node with the third network node by:
activating an interconnection between the second network node with the third network node by creating an access-list using IP-addresses defined for each node; and
applying the access-list on a router element provided in said gateway.
