Kamijima Town

Integrated management of the network connecting the islands of the Seto Inland Sea with AMF

In Kamijima-cho, Ochi-gun, Ehime Prefecture, which consists of 25 islands in the Seto Inland Sea, we reviewed the complicated network and introduced Allied Telesis network equipment. With the AMF (Autonomous Management Framework) function, we built a network that enables integrated management and quick recovery from failures.
