<p>PROBLEM TO BE SOLVED: To provide a packet processor capable of speedy and effective packet filter processing even when the access control program of many lines is given. SOLUTION: A packet filter part 2 is provided with an access control program parallel compiler part 3 analyzing the depending relation of an access control program needing successive interpreting, converting it to an intermediate code 4 consisting of an access control rule which can be interpreted in parallel based on a route condition, detecting the same comparing parameter included in the packet condition of the intermediate code 4 or a comparing parameter in an involving relation and simplifying this, and a packet filter execution part 5 deciding the transfer or abolition of a packet based on the intermediate code 4.</p> |
