Challenges faced by Current Internet IoM(Internet of Media),IoT(Internet of Things),IoS (Internet of Services)have pushed Internet to its limit in terms of: Performance: 0.5Million backbone routers,9M BGP routes,1T webpage items on Google,15hours video content added into video websites per minute, ..60%increase in Internet traffic flow p.a. Furthermore,IoT makes billions and trillions of"things"connected into the Internet! The Internet becomes huge and more complex. ■ Security: e.g.,90M visa card users hacked in Europe and North America at 2007; DNS server of Storm (Video)Co.being attacked at 2009,leading to 15 provinces'network malfunction in China. 3

Path to Future Internet:Dirty Slate Solutions:back-compatible,evolutionary,incremental Quality of Service problem?Then IntServ/DiffServ More efficient routing?->MPLS(Multi-Protocol Label Switching) Security problem?Then IP VPN:Virtual Private Network Not enough IP addresses?Then IPv6. Mobility problem?Then Mobile IP or MIPv6 ■Initiatives: NGI,Internet2 at US,Ambient Network in EU, APAN in Japan,CNGI in China. ■Problems: Adding patches and making the Internet more complex and thus more difficult to achieve global optimization. Limiting the further development of the Internet. 5
