PROBLEM TO BE SOLVED: To provide a virtual network system that can monitor packets at all times and analyze a trouble event without any separate equipment of a monitoring system, so that no load is applied to the system and the cost can be suppressed without influencing the operation of the configured system and execution of services.SOLUTION: A virtual network system includes a packet receiver 1 for receiving packets from a network, a packet copying part 2 for copying a packet from the packet receiver 1, a first packet buffer part 3 for temporarily storing the original packet received from the packet copying part 2, a second packet buffer part 4 for temporarily storing the copied packet received from the packet copying part 2, and a network application part 5 which operates under a virtual environment, performs normal network processing on one of the original packet and the copied packet, performs constant monitoring on the other packet and performs analysis by using the constantly monitored packet when a trouble event occurs.SELECTED DRAWING: Figure 1 |
