Abstract
A communication management control system manages exchange of data between an external information processing unit and an internal information processing unit via a router. The communication management control system includes a first local area network (LAN) coupled to the internal information processing unit, a second local area network (LAN) coupled to the router, and a communication control unit coupled to the first LAN and the second LAN.
Claims12
A communication management control system which manages exchange of data between an external information processing unit and an internal information processing unit via a router, comprising:
- a first local area network (LAN) coupled to the internal information processing unit;
- a first communication control unit and a plurality of second communication control units;
- and
- a second local area network (LAN) coupled to the router and directly coupled to said second communication control units;
- said first communication control unit being coupled to said first LAN, each of said second communication control units being directly coupled to both said first LAN and said second LAN,
- the data being received by said first communication control unit from said internal information processing unit and selectively distributed to one or more of said second communication control units.
A communication control unit which exchanges data between an external information processing unit and an internal information processing unit via a router, said internal information processing unit being provided within a communication management control system having a first local area network (LAN) which provides a data processing service and a second local area network (LAN) which is coupled to the router and provides a communication service, said communication control unit comprising:
- a first controller;
- a plurality of second controllers;
- first means for coupling the first controller to the internal information processing unit and the first LAN;
- and
- second means for directly coupling each of the second controllers to both the second LAN and the first LAN, the data being received by said first controller from said internal information processing unit and selectively distributed to one or more of said second controllers.
A computer program product which stores a program for causing an exchange of data between an external information processing unit and an internal information processing unit via a router, said internal information processing unit being provided within a communication management control system having a first local area network (LAN) which provides a data processing service and a second local area network (LAN) which is coupled to the router and provides a communication service, said computer program product comprising:
- a first controller;
- a plurality of second controllers;
- first means for coupling the first controller to the internal information processing unit and the first LAN;
- and
- second means for directly coupling each of the second controllers to both the second LAN and the first LAN, the data being received by said first controller from said internal information processing unit and selectively distributed to one or more of said second controllers.
A computer program controlling an exchange of data between internal and external information processing units via a router, in a system having a first local area network (LAN) coupled to a first communication control unit and providing a data processing service and a second local area network (LAN), coupled to the router and providing a communication service, by:
- causing the internal information processing unit to couple to the first LAN;
- causing a plurality of second communication control units each to be directly coupled to the first LAN and directly coupled to the second LAN;
- and
- causing the data being received by said first communication control unit from said internal information processing unit and selectively distributed to one or more of said second communication control units.
A system to exchange data between an external information processing unit and an internal information processing unit, comprising:
- a first local area network (LAN) coupled to the internal information processing unit;
- a second LAN in communication with the external information processing unit;
- a first communication control unit coupled to said first LAN;
- and
- a plurality of second communication control units each directly coupled to both said first LAN and said second LAN.
