Abstract

In a communication apparatus processing a packet transmitted/received by a device connected to a network, an identifying/processing policy storing portion stores a basic identifying policy and processing policy for determining an identification and processing of a packet corresponding to transmitted information from a device, a transmitted information extractor extracts the transmitted information, and a controller determines a rule for identifying and processing a received packet based on the identifying policy and the processing policy corresponding to the transmitted information extracted and prepares an identifying rule/processing rule setting table which indicates the rule. A packet processing identifies the received packet based on the identifying rule and processes the identified packet based on the processing rule.

Claims

1. A communication apparatus comprising:

an identifying/processing policy storing portion storing a basic identifying policy and processing policy for determining an identification and processing of a packet corresponding to transmitted information from a device;

a transmitted information extractor extracting the transmitted information;

a controller determining a rule for identifying and processing a received packet based on the identifying policy and the processing policy corresponding to the transmitted information extracted, and preparing an identifying rule/processing rule setting table which indicates the rule; and

a packet processor identifying the received packet based on the identifying rule and processing the identified packet based on the processing rule.

2. The communication apparatus as claimed in claim 1, wherein the transmitted information comprises device information, service information, or user information of the device included in any of an advertisement message, a communication packet, and a control packet.

3. The communication apparatus as claimed in claim 1, wherein the identifying/processing policy storing portion stores the identifying policy and the processing policy concerning device information, service information, or user information corresponding to the transmitted information.

4. The communication apparatus as claimed in claim 1, wherein the identifying policy includes a policy identifying a packet based on at least one of a transmitting source address, a destination address, a protocol type, a transmitting source port number, and a destination port number of the packet.

5. The communication apparatus as claimed in claim 1, wherein the processing policy includes a policy concerning at least one of a service quality class, filtering, and routing of the packet.

6. The communication apparatus as claimed in claim 1, wherein the identifying rule/processing rule setting table has at least one of a transmitting source address, a destination address, a protocol type, a transmitting source port number, and a destination port number value identified by the identifying policy as the identifying rule.

7. The communication apparatus as claimed in claim 1, wherein the identifying rule/processing rule setting table has at least one of a service quality class, filtering, and a routing value of the packet as the processing rule.

8. The communication apparatus as claimed in claim 1, wherein the communication apparatus comprises a gateway apparatus, a router, a bridge, or a switch.

9. The communication apparatus as claimed in claim 1, wherein the controller deletes from the identifying rule/processing rule setting table the identifying rule and the processing rule which have not been accessed for a predetermined time.

10. The communication apparatus as claimed in claim 1, further comprising a notifying message generator notifying the identifying rule and the processing rule to another communication apparatus.

11. The communication apparatus as claimed in claim 1, wherein the transmitted information extractor receives the identifying rule and the processing rule from another communication apparatus, and the controller prepares the setting table based on the identifying rule and the processing rule.

13. The communication apparatus as claimed in claim 1, further comprising a detailed information acquiring portion inquiring, of the device, an acquiring destination of the identifying policy and the processing policy corresponding to the transmitted information not stored in the identifying/processing policy storing portion, and acquiring the identifying policy and the processing policy corresponding to the transmitted information from the acquiring destination.

14. The communication apparatus as claimed in claim 1, further comprising a connecting device information storing portion associating a value indicated by the identifying rule with the transmitted information of the device, and a man-machine interface;

the controller converting the transmitted information of the device designated by the man-machine interface into a value of the identifying rule referring to the connecting device information storing portion, and converting the value of the identifying rule into the transmitted information of the device to be provided to the man-machine interface.

15. The communication apparatus as claimed in claim 1, further comprising a transmitted information identifying condition table indicating an identifying condition of the transmitted information to be extracted;

the transmitted information extractor extracting the transmitted information based on the transmitted information identifying condition table.

16. The communication apparatus as claimed in claim 15, wherein the condition comprises a condition concerning device information or user information.

17. The communication apparatus as claimed in claim 1, further comprising a check table indicating that the transmitted information has already been extracted or is not required to be extracted;

the transmitted information extractor extracting the transmitted information based on the check table.

12. A communication apparatus comprising:

an identifying/processing rule receiver receiving an identifying rule and a processing rule prepared based on an identifying/processing policy corresponding to transmitted information from a device, and preparing an identifying rule/processing rule setting table indicating a rule for identifying and processing a received packet based on the identifying rule and the processing rule; and

a packet processor identifying the received packet based on the identifying rule and processing the identified packet based on the processing rule.
