 Internet is one of the most technical achievements of our time, but this technology is not new. Its idea goes back to the 1960s due to the work by Paul Berlin and Don Davies on packed switching. So around 1970s, TCP-IP protocols were invented, but since then it's already about 50 years. It has been very successful, but right now new applications are coming up, are emerging. For example, holograms, holographic type of communications, vertical industry. So what they need is something that currently Internet cannot support, for example, that currently Internet can only support based on effort services, differentiated services and traffic engineering. But it doesn't guarantee throughput or latency. For example, like in autonomous driving, in some machine-critical applications, we need a guaranteed latency. And in some other applications, we do not allow packets to be lost. So current network is lossy. So when you send a packet out, the packet can be lost. So we want the future network to be lossless networking. So third is that because holograms need a very high throughput. Usually like a person like me, this size, it requires more than four terabit per second. But according to the TCP-IP, in order to have a high throughput and your network is lossy, so your latency has to be very short. So there are some contradictions there. So on one hand, we need a high throughput. On the other hand, we need a very low latency. So these two requirements cannot be met together. So Network 2030 will try to solve such problems there. It's a long journey from here to get there. So it needs a community to work together from different countries. I think ITU has made a very good step by setting up this focus group. So we have worked together for about seven to ten months. We have made tremendous progress. People have agreed to the problems we have identified. For example, Internet is the best effort for the future. We need the best guarantee, best precision services. So we need a lossless networking. We also need something new that's a holographic type of communications. For example, like a holographic concert. One single thing in a city. His band plays in another city. So his dancers perform even in third city. So we can teleport their hologram to one place. We can have a holographic concert there. So right now we have identified those services and drawbacks, limitations from the Internet. And also we have many workshops here. People just propose their solutions. So right now we have, you know, where the direction we are going. We are working on some solutions. Hopefully in the next year, the solution will be coming up. As I see that, so people have made a few, like four to six competing solutions, either at level two or level three and level four. So we also, in the architecture group, we have already identified some issues. For example, like a private Internet and a public Internet. So many nets are emerging. So how to converge them together, sometimes how to select the best path, like to forward the packet from one place to another to guarantee lossless networking, latency guaranteed, high throughput, trustable infrastructure.
