Theme : “Trust”and the Internet

An Internet transaction between two or more verified
or verifiable personae should be predictable within
the context, and when appropriate traceable,auditable, and non-repudiable.
z Two or more personae that consider themselves to bein the same context should be able to perform
relevant transactions. The choices available toconnected personae in the Internet include anything
they agree on.
z Maintain “Layer”(Horizontal) servive/business modelz1

My “CANADA”
z Canada is “multi-culture”
z Canada has “liberty”

and “anonymity”
z Canada has “fairness”, no discriminationz Canada reacts “predictably”
z Canada is “safe”
z Canada provides “commons”
z Canada provide “opportunity”

User and end-station is poor and stupid
Users’ terminal only turns on, when it’s needed
Fixed terminal is far major and superior than mobile
nodes“Service” must be provided either by provider or byenterprise.
Cost of transmission, store and copy, is not little, butnegligible.

Naive Question on NGN
z Look like this ?

ITU-T NGN ≠ ETSI TISPAN ≠ IMS/MMDz ITU-T NGN ≠ NTT NGNz NTT NGN ≠ KDDI NGN(≒IMS)
zz NGN is yet another BISDN

IP packet Í 48 Bytes cellz SNI Í TINA/AINzz Would ITU-T SG11 people believe theInteroperability can be achieved whenever they
complete the standardization documents ?
z Why T-MPLS is conflictive with IETF’s MPLS
specification ?

zMarket• Domestic Standard
z Radio Frequency of FM radio– TTC
z Cell-phone system– ARIBz PSTN system

Reasons(?) :1. Because of enough large domestic market size,
leading to encourage bundled and closed businessmodel.
2. Too high quality engineers, who may propose
better technology
3. lack of enough Stake-Holder participation
