1. A traffic control computing device comprising:
- a traffic control interface to connect to traffic control devices which control traffic in a network;
a traffic control request interface to connect to traffic control request detecting devices which determine whether a traffic control must be executed by said traffic control devices;
a first storage device in which information about traffic control received via the traffic control request interface is stored;
a traffic control computing unit connected to said traffic control interface, and connected to said traffic control request interface, and connected to said first storage device, wherein said traffic control computing unit computes traffic control algorithms based on traffic control requests stored in the first storage device and sends the traffic control algorithms to said traffic control interface.

Abstract
By using combinations of a plurality of firewall techniques and making these techniques work together appropriately, problems presented with popular use of always-on Internet connections and end-to-end communications using IPv6 are resolved. This flexible manner of applying access control techniques grants favors to corporate network users, resulting from the popular use of always-on Internet connections and IPv6, e.g., the promotion of teleworking and virtual offices. A traffic control computing device which processes control requests from traffic control devices, provided in a network, coordinates the control actions of the individual traffic control devices appropriately.

18. A control method for a network comprising:
-
providing traffic control devices which control traffic in the network, traffic control request detecting devices which detect what traffic control must be executed in the network, and a traffic control computing device which processes a traffic control request based on said detected traffic control requirement, receiving, by said traffic control computing device, information (hereinafter referred to as first information) which comprises the identifiers of said traffic control request detecting devices, the detection functions of the traffic control traffic control request detecting devices, and traffic control requests which are now issued from the traffic control request detecting devices; and
storing the acquired first information into a storage device, wherein, upon receiving a new traffic control request from one of said traffic control request detecting devices, said traffic control computing device determines whether the newly received traffic control request conflicts with any of the traffic control requests stored in said storage device, if no conflict is found, calculates a control algorithm, based on the received traffic control request, and transmits the calculated control algorithm to the appropriate one of said traffic control devices. - View Dependent Claims (19)
