PROBLEM TO BE SOLVED: To improve accuracy in the measurement of the number of lost packets, when a test target network is connected to an external network through link aggregation.SOLUTION: An SW 1 identifies the number of user packets which are relayed through each of a plurality of physical links, for a plurality of physical links of an SW 4 in link aggregation, to identify the number of user packets relayed by the SW 1 and the SW 4. Based on the number of user packets relayed by each of the SW 1 and the SW 4, the SW 1 derives the number of lost user packets that occurs in a section ranging from the SW 1 to the SW 4.SELECTED DRAWING: Figure 11 |
