First Claim
Patent Images
1. A concentrated network interconnection control system, comprising:
- a plurality of interfaces connected to individual user networks configured to transmit and receive packets;
a network interconnection controller including a plurality of control function parts, each control function part independently provided for a respective pair of user networks and defining rules for connections between one of terminal addresses in one of said pair of user networks and one of terminal addresses in another one of said pair of user networks; and
a function association selector configured to associate each interface to one of the plurality of control function parts, said function association selector including a function managing table configured to store an association between each interface and a corresponding one of the control function parts, an identifier imparting part configured to retrieve an identifier from the function managing table, the identifier identifying the corresponding one of the control function parts associated with a first interface that has received a packet, and configured to impart the identifier to the packet, a function selector configured to transfer the packet to the control function part identified by the imparted identifier, and an output interface selector configured to select a second interface corresponding to the identifier imparted to the packet, via the function managing table, and configured to deliver the packet to the selected interface.

Abstract
Interfaces IF-A to IF-D connected to individual user networks, control function parts 41C1, 41C2 for providing an independent connection control function for each pair of user networks, and a function association selector 43 for associating each of the interfaces IF-A to IF-D to either control function part 41C1 or 412 are provided. User networks connected to respective interfaces IF-A to IF-D are connected to the control function parts 41C1, 41C2 to which they are previously associated, thus implementing communications between a plurality of user networks with a single system.
