Innovation - NICE functional architecture
（Ｎｅｔｗｏｒｋ　Ｉｎｔｅｌｌｉｇｅｎｃｅ　ｃａｐａｂｌｉｔｙ　ｅｎｈａｎｃｅｍｅｎｔ）
Ø In ITU-T Feb 2012 meeting,
we propose to start a new
draft Recommendation
Y.NICE-arch
Ø NICE architecture reflects
enhancement requirements
for five main capabilities
Geneva, Switzerland, 11 June 2012
Ø Openness：Unified interfaces,
adaption of services and
network
Ø Awareness :
Users, application,network
based perception and analysis
Ø Optimization：
Network virtualization, content
routing, resource provision and
traffic optimization
Ø Coordination：
Multi-access coordination and
service experience consistent
Ø Evolution： a new hierarchical
architecture, standardized
protocol and interface,
compatible with existing

Elastic Ethernet Service Attributes
On-demand change of EVC or UNI attributes for specific time period
Once time period ends, revert back to prior state
Investigating on-demand and reservation models
Example Elastic Attributes
Increase CIR of existing EVC
Add or Remove UNI endpoints in
multipoint EVP-LAN or EVP-Tree service
On-demand bandwidth approaches
Based on bandwidth usage (X MBytes/month)
Based on CIR and/or EIR (200 Mbps CIR and 400 Mbps EIR)
