4 Motivation - Why New Generation Network? In future society Complexity and diversity of human society increases universal communication? People and information become more closely small interconnected devices? authentication? The network of future should benefit such human society worldwideguaranteed Reflect this diversity and complexity dependability? service? Support rich life, Give birth to a new culture and science The network should be embedded in the Adding real world Functions to benefit?? society Current Internet faces flow-label Human support insufficiency Capacity of transmission/exchange Electric power consumption anycast 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 Original Internet Architecture Difficulty in building sustainable & evolvable network (patch??)
