Why New Generation Network?• Current & near-future situation

– The Internet has grown as the most important worldwide ICT infrastructure.– Telephone network will be renovated by NGN (Next Generation Network), of

which transport is constructed by IP network system.– NGN is expected to provide sophisticated solutions for solving the problems

in the Internet, e.g. QoS, Security, etc.• However, we have still many problems. For example:

– Large capacity of transmission/exchange (x103 by 2020 (1 Pbps))– Electric power consumption of core router (1 nuclear plant power

generation per 100 devices of 1Pbps electronic router)– Difficulty of guarantee of bandwidth (limit of packet switching system)– Difficulty of congestion control (bw-delay problem, fairness of users)– Difficulty of avoidance or fast recovery of break down (several tens

of seconds’ order needed for rerouting in wide areas)– Difficulty in introducing plural gateways, seamless mobility

(connection termination)– …

– Difficulty in building sustainable & evolvable network (patch??)
