PORT SWITCHING METHOD, ANALYSIS DEVICE, AND RECORDING MEDIUM

摘要

A port switching method performed by a processor included in an analysis device coupled to a first port and a second port which are included in at least one of a plurality of switches, the port switching method includes receiving a first copy packet from the first port; determining whether the first copy packet succeeded a second copy packet based on sequence information of the first copy packet, and based on sequence information of a second copy packet received before the receiving; specifying a target port outputted the first copy packet to the first port, the target port being included in a target switch among the plurality of switches when it is determined that the first copy packet did not succeed the second copy packet; and causing the target switch to transmit, from the target port, a third copy packet generated at the target switch to the second port.

1. A port switching method performed by a processor included in an analysis device coupled to a first port and a second port, each of the first port and the second port being included in at least one of a plurality of switches, the plurality of switches being capable of copying a packet to generate a copy packet, the port switching method comprising:
receiving a first copy packet from the first port; determining whether the first copy packet succeeded a second copy packet based on sequence information of the first copy packet, and based on sequence information of a second copy packet received before the receiving; specifying a target port outputted the first copy packet to the first port, the target port being included in a target switch among the plurality of switches when it is determined that the first copy packet did not succeed the second copy packet; and causing the target switch to transmit, from the target port, a third copy packet generated at the target switch to the second port.
