Abstract
A network system, management server, and OAM test management method for grouping the virtual networks, selecting a test target for each group, and lowering the network load and the operating load in the OAM testing. Grouping the multiple virtual networks based on their physical topology and selecting a representative virtual network for each group, allows selecting a test target virtual network from among the representative virtual networks for the virtual network selected by the operator and executing tests.
