1. A method comprising:
receiving a request associated with a packet, the request including an identifier (ID);
selecting at least one entry in a table indicated by the ID, the entry providing a starting address associated with a set of rules;
determining a subset of rules based on at least one field of the request, the subset of rules being a portion of the set of rules;
applying the at least one field against the subset of rules; and
outputting a response signal indicating whether the at least one field matches at least one rule of the subset of rules.
2. The method of claim 1, wherein the request includes a key format table index.
3. The method of claim 2, further comprising parsing the request based on the key format table index.
4. The method of claim 1, wherein the set of rules is a portion of rules stored in a memory.
5. The method of claim 1, wherein determining a subset of rules includes determining at least one bucket, the at least one bucket including pointers to the subset of rules.
6. The method of claim 5, wherein the at least one bucket includes a plurality of buckets, and wherein the entry includes a node associated with the plurality of buckets.
7. The method of claim 6, wherein processing the entry includes processing the node to determine the plurality of buckets.
8. The method of claim 6, wherein the node is associated with the plurality of buckets via at least one intermediary node.
9. The method of claim 1, wherein the subset of rules is ordered by priority.
10. The method of claim 9, wherein the at least one field is applied against the subset of rules in a descending order of priority.
11. The method of claim 10, wherein the response signal is output after a first match between the at least one field and the subset of rules is located.
12. The method of claim 11, wherein applying the at least one field against the subset of rules is stopped after the first match is located.
13. The method of claim 1, wherein selecting at least one entry in a table indicated by the ID includes selecting a plurality of entries.
14. The method of claim 13, further comprising selecting among a plurality of match results based on a predetermined priority, each match result corresponding to one of the plurality of entries.
15. An apparatus for processing a packet comprising:
a first engine configured to:
receive a request associated with a packet, the request including an identifier (ID);
select at least one entry in a table indicated by the ID, the entry providing a starting address associated with a set of rules; and
determine a subset of rules based on at least one field of the request, the subset of rules being a portion of the set of rules; and
a second engine configured to apply the at least one field against the subset of rules and output a response signal indicating whether the at least one field matches at least one rule of the subset of rules.
16. The apparatus of claim 15, wherein the request includes a key format table index.
17. The apparatus of claim 16, wherein the first engine is further configured to parse the request based on the key format table index.
18. The apparatus of claim 15, wherein the set of rules is a portion of rules stored in a memory.
19. The apparatus of claim 15, wherein the first engine determines at least one bucket, the at least one bucket including pointers to a subset of rules.
20. The apparatus of claim 19, wherein the at least one bucket includes a plurality of buckets, and wherein the entry includes a node associated with the plurality of buckets.
21. The apparatus of claim 20, wherein processing the entry includes processing the node to determine the plurality of buckets.
22. The apparatus of claim 20, wherein the node is associated with the plurality of buckets via at least one intermediary node.
23. The apparatus of claim 15, wherein the subset of rules is ordered by priority.
24. The apparatus of claim 23, wherein the at least one field is applied against the subset of rules in a descending order of priority.
25. The apparatus of claim 24, wherein the response signal is output after a first match between the at least one field and the subset of rules is located.
26. The apparatus of claim 25, wherein applying the at least one field against the subset of rules is stopped after the first match is located.
27. The apparatus of claim 15, further comprising a third engine configured to retrieve the subset of rules from a memory.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A DNA chip with a micro-channel for DNA analysis of DNA included in an analyte according to a PCR method, the DNA chip comprising:
a first layer made of silicon; and
a second layer made of plastic,
wherein the second layer is formed on a partial area of the first layer, and
the second layer comprises:
a liquid transporting system; and
a sensor,
the first layer includes a PCR reactor provided on an area on which the second layer is not formed.
2. The DNA chip according to claim 1, wherein the PCR reactor is provided on an area closer to an end of the first layer than to the center of the first layer.
3. The DNA chip according to claim 2, wherein at least two PCR reactors are provided on the first layer, the at least two PCR reactors are connected to each other.
