Claim 19:
20. A system for diagnosing network performance, the system comprising:
a switching device provided between a first entity and a second entity; and
an apparatus for diagnosing network performance for obtaining at least one mirrored packet for at least one packet transmitted between the first entity and the second entity based on mirroring from the switching device, calculating performance related indicators representing performance of a network service associated with the first entity and the second entity based on at least a part of information included in the at least one mirrored packet, determining whether a problem of the network service occurs based on at least a part of the performance related indicators, and storing the calculated performance related indicators,
wherein the apparatus for diagnosing network performance is configured to
compare at least one of bits per second (BPS) information representing a transmission bit size of a data per second and connections per second (CPS) information representing a number of new sessions connected per second with at least one of a threshold value associated with the BPS information and a threshold value associated with the CPS information, and
when at least one of the CPS information and the BPS information is greater than at least one of the threshold value associated with the CPS information and the threshold value associated with the BPS information, determine a problem of BPS excess or CPS excess to occur.
