 We achieved a lot of things for the last several decades in the network area, but still we have too many things to solve for the new network architecture. So, NETO-23 focused on ITUT is a platform to discuss the new network architecture. There are several challenges that I'm thinking for the new network architecture in the near future. The first one will be the higher data rate. The holographic telecommunications services require TeraVPS bandwidth, but now the network cannot provide the TeraVPS bandwidth, so we have to solve that. And the next one is the complexity. Lots of things are connected to the network now. It will cause too much complexity in the network, so we have to solve that. Manual computation cannot solve that anymore, so network automation will solve that. And the next one will be N10 determined QOS. NETO is not the delivery system, data delivery system anymore. It will become the new neural system of our society. If it pairs, then it will cause too much problem. It will kill people also. So, the network architecture will have to solve the deterministic QOS in the near future. And the third one will be security issue. It is called also trustworthiness in the network. So for now, the internet was not designed considering security in the beginning, but now as a critical infrastructure of our society, NETO have to consider trustworthiness, including security. And the next one is privacy. Privacy is becoming more and more important. Data is generated from lots of devices, from your device, include lots of your personal information. If it is not protected well, then it will also cause too much problem. So, new network architecture have to solve the privacy issue in the near future. So, including all those kind of problems or challenges in the near future, the new network architecture will be provided, and NET23 focus will be in ITU will challenge that.
