A method for packet processing according to a lookup table, comprising:
- receiving a packet, wherein the packet includes a packet header information, and the packet header includes control information;
- providing a lookup table with M entries, wherein each entry includes N conditions and a result/action indicator, and the M entries are sorted in a priority order;
- matching the information with the N conditions;
- and
- applying the result/action indicator in the matched entry with the highest priority on the packet.
A system for packet processing according to a lookup table, comprising:
- a receiver for receiving a packet, wherein the packet includes a packet header, and the packet header consists of control information;
- a memory, storing a lookup table with M entries, wherein each entry includes N conditions and a result/action indicator, and the M entries are sorted in a priority order;
- and
- a processor, wherein the processor matches the information with the N conditions, and applies the result/action indicator in the matched entry with the highest priority on the packet.
