A packet transfer device comprising:
- a memory;
- and
- a processor coupled to the memory and the processor configured to:
- detect a first packet of a predetermined size,
- detect a second packet whose data in a predetermined area matches a specific pattern, the second packet being included in a group of the first packet, and
- count a number of the second packet.
3 more elements
A method for setting a counter, the method comprising:
- setting, to a size detector, a size of a first packet to be detected by the size detector, based on path information of a path on which a packet is transferred;
- and
- setting, to a pattern detector, a position of a data area of a specific pattern included in a second packet to be detected by the pattern detector, based on the path information, the second packet being included in a plurality of first packets detected by the size detector, by a processor.
A computer-readable non-transitory recording medium storing a program that causes a computer to execute a procedure, the procedure comprising:
- setting, to a size detector, a size of a first packet to be detected by the size detector, based on path information of a path on which a packet is transferred;
- and
- setting, to a pattern detector, a position of a data area of a specific pattern included in a second packet to be detected by the pattern detector, based on the path information, the second packet being included in a plurality of first packets detected by the size detector.
