Motivation - Why New Generation Network?• In future society…

– Complexity and diversity of human society increases– People and information become more closely interconnected

• The network of future should benefit such human society worldwide– Reflect this diversity and complexity– Support rich life, Give birth to a new culture and science– The network should be embedded in the real world to benefit society

• Current Internet faces …– Human support insufficiency– Capacity of transmission/exchange

– Capacity of transmission/exchange– Electric power consumption– Difficulty of guarantee of bandwidth– Difficulty of congestion control– Difficulty of avoidance or fast recovery of break down – Difficulty in introducing plural gateways, seamless mobility– …

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

How to get to New Generation NetworkHow to get to New Generation Network(Seamless heterogeneous networking case)(Seamless heterogeneous networking case)

• Identifier & locator separated net architecture is necessary in NWGN

– To provide connectivity of heterogeneous network seamlessly

• ID/Loc split concept was discussed in ITU-T SG13

– Conceptual architecture in Y.ipsplit (Y.2015 “General requirements for ID/locator separation in NGN”) is better for migration to NWGN
