METHOD, APPARATUS, AND PACKET ANALYZING SYSTEM

摘要

A method includes receiving a first packet, the first packet being including a first packet identifier and a first error detection code, storing first information indicating the first packet identifier and second information indicating the first error detection code, receiving a second packet, the second packet being including a second packet identifier and a second error detection code, comparing the second packet identifier and the second error detection code with the first information and the second information, respectively, in response to a determination that the second packet identifier corresponds to the first information and the second error detection code corresponds to the second information, discarding the second packet, in response to a determination that at least one the second packet identifier and the second error detection code does not correspond to the first information and the second information, providing the first packet and the second packet for a packet analysis.

主权项

1. A method comprising:
receiving a first packet, the first packet being transmitted from a first packet capture point in a network, the first packet including a first packet identifier and a first error detection code (EDC); storing first information indicating the first packet identifier and second information indicating the first EDC; receiving a second packet, the second packet being transmitted from a second capturing point in the network, the second packet including a second packet identifier and a second EDC; comparing the second packet identifier and the second EDC with the first information and the second information, respectively; and in response to a determination according to the comparing that the second packet identifier corresponds to the first information and the second EDC corresponds to the second information, discarding the second packet, and in response to a determination according to the comparing that at least any one the second packet identifier or the second EDC does not correspond to either of the first information or the second information, providing the first and second packets for a packet analysis.
