New IP and Market Opportunities Richard Li Chief Scientist, Network Technologies Futurewei, USA IEEE International Conference on High Performance Switching and Routing (HPSR) 2020 May 11-14, 2020 Futurewei Technologies, Inc. Acknowledgement and Disclaimer • New IP is under research and development by research scientists and professional engineers across different countries and different organizations • Some results of this talk may have appeared in ITU, IEEE and ACM publications 2 The Internet has been very successful! But can it sustain all new applications in decades to come? Can we rest here and take the Internet as it is forever?
