1. FUTURE INTERNET: PROPOSAL “PROBLEMS IN CURRENT INTERNET” M S Siddiqui [ID 2008311200] siddiqui@khu.ac.kr Networking LAB, KHU 2008-09-29

2. Problem Identification  Addressing (IP addressing) in Internet.  Issues  Scalability  Routing  Multi-homing & Renumbering  Spoofing (security) 2008-09-29 2 Future Internet - Networking LAB, KHU

3. Proposal Current addressing scheme is not good and needs to be replaced by a better efficient and secure addressing scheme Description  Scalability in IP addressing  Solved by NAT?  Solved by IPv6?  Routing table alarmingly increasing  Induce delay?  Storage at routers ?  Multi-homing with different ISPs causes renumbering of address  IP address spoofing is the root of DDoS attacks 2008-09-29 3 Future Internet - Networking LAB, KHU
