Having identified three missing links in the current Internet architecture based on our long-term experiences of designing and operating large-scale backbones, we put forward a new, but incrementally deployable, network schemc address switching. The address switching has both the advantages of packet switching and circuit switching; it supplies the missing links in the current Internet architecture and can reform the Internet traffic. Our analysis, protocol design and ex- periments indicate that the address switching can greatly improve the quality of service （QoS）, security and routing scalability of today＇s Internet. So it can provide flexible, high-performance and ＂per-service＂ networking for the scientific research communities. Moreover, it can provide a fairer and more sustainable business model for the commodity Internet.展开更多
