Abstract(in English)	Internet traffic has increased by 20 to 30% per year. Then the network cost will increase more and more. On the other hand, the competition between carriers is becoming increasingly intense. In addition, the fact that Over The Top is beginning to invest and own networks makes it more difficult to raise profits. In this presentation, I present NTT Communications' efforts to solve problems such as cost reduction for network equipment and expansion of profits, along with several examples such as introduction of high speed, large capacity equipment and activities for disaggregation.
