5. The device of claim 1 , wherein, a respective transparency indication is assigned to each of the pre-determined control data and a respective transparency information is assigned to each of the logical ports, and wherein when searching for control data received from a respective one of the logical ports, a respective one of the pre-determined control data is omitted from the search for the control data when the transparency indication of the respective pre-determined control data matches the transparency information of the respective logical port.
6. The device of claim 1 , wherein the data received from at least two different logical ports uses different protocols having different control data.
7. The device of claim 1 , wherein the first set of pre-determined control data is associated with one or more communication protocols.
8. The device of claim 1 , wherein a respective one of the control data is assigned to a respective action that is to be performed when the respective control data is detected.
9. The device of claim 1 , wherein a first subset of the first set of pre-determined control data is assigned to a first one of the plurality of logical ports and a second subset of the first set of pre-determined control data is assigned to a second one of the plurality of logical ports, and wherein at least one element in the first set of pre-determined control data is excluded from the first subset and the second subset.
10. A device, comprising:
at least one input terminal to receive data comprising control data from a plurality of logical ports;
a memory configured to store a first set of control data; and
a detector, coupled to the at least one input terminal and to the memory, and configured to search for the control data, which are comprised in the data received at the at least one input terminal, in the memory, wherein a respective subset of the first set is assigned to a respective one of the logical ports and the detector ignores the respective subset when searching for the control data received from the respective logical port, wherein the respective subset is defined by a respective transparency indication comprising one or more bit combinations to be excluded.
11. The device of claim 10 , wherein the memory is a ternary content-addressable memory.
12. The device of claim 10 , wherein a respective one of the control data is assigned to a respective action that is to be performed when the respective control data is detected.
13. A method, comprising:
receiving data comprising control data from a plurality of logical ports; and
searching for the control data in a first set of pre-determined control data, wherein a respective subset of the first set is assigned to a respective one of the logical ports and the respective subset is excluded from the first set when searching for the control data received from the respective logical port, wherein the respective subset is defined by a respective transparency indication comprising one or more bit combinations to be excluded.
14. The method of claim 13 , wherein the first set of the pre-determined control data is stored in a ternary content-addressable memory.
15. The method of claim 13 , wherein the respective transparency indication is assigned to each of the pre-determined control data.
16. The method of claim 13 , wherein the respective transparency information is assigned to each of the logical ports.
17. The method of claim 13 , wherein, a respective transparency indication is assigned to each of the pre-determined control data and a respective transparency information is assigned to each of the logical ports, and wherein when searching for control data received from a respective one of the logical ports, a respective one of the pre-determined control data is omitted from the search for the control data if the transparency indication of the respective pre-determined control data matches the transparency information of the respective logical port.
18. The method of claim 13 , wherein the data received from the logical ports are arranged in data packets and/or frames.
19. The method of claim 13 , wherein the first set of pre-determined control data is associated with one or more communication protocols.
20. The method of claim 13 , wherein a respective one of the control data is assigned to a respective action that is to be performed when the respective control data is detected.
21. The method of claim 13 , wherein a first subset of the first set of pre-determined control data is assigned to a first one of the plurality of logical ports and a second subset of the first set of pre-determined control data is assigned to a second one of the plurality of logical ports, and wherein at least one element in the first set of pre-determined control data is excluded from the first subset and the second subset.
22. A device, comprising:
a plurality of logical ports; and
a detector, receiving data comprising control data from the plurality of logical ports, and configured to search for the control data in a first set of pre-determined control data, wherein a respective subset of the first set is assigned to a respective one of the logical ports and the respective subset is excluded from the first set when searching for the control data received from the respective logical port, wherein the respective subset is defined by a respective transparency indication comprising one or more bit combinations to be excluded.
