Networking, Storage and ComputingTestbed for the Future Internet

Satisfying ³Global Triple-Any´: Anything Anytime for Anyone

Yoram Ofek

Department of Information and Communication TechnologyUniversity of Trento ± Italy

IST 2006, Helsinki, 21-23 November, 2006



2Ofek 2006 ± University of Trento

Motivations

Two Internet transitions:1. From business to home

The capacity per home will equal to campus capacity

2. From broadcast to (all) on-demand:Triple-any: anyone/anything/anytime

Global scale: from anywhere to anywhere

Thus, it is envisioned that >90%

of IP traffic will be to home (mobile) users

Consequently,who will pay is a primary issue




BackgroundInternal

Motivated by the external Internet activitiesthe Provincia Autonoma di Trento ± PAT:

Deploying 800 km of optical infrastructure For providing wide variety of services

to all residence of PAT

It is the intension of PAT that the Univ. of Trento will constructoptical networking testbedalong the 800 km fiber infrastructure

Focusing on the two Internet transitions 1. From business to home

2. From broadcast to on-demand

Optical Testbed Motivations

Framework for global triple-anyAnyone/anything/anytime

Anyone:

All ages and technical skills wherever they are Anything:

All content with any formats and any player

Anytime: ON-DEM ANDE.g., peer-to-peer, client-server, «

Challenges

1. Cisco CRS-1 [carrier routing system]:Was announced as 92 Tb/s is actually only:

92/(2*72) § 0.64 Tb/s per chassis

Factor of 2 improvement in 5 years/$500 millions

2. The Internet is doubling: 18-monthOnOn--demanddemand (e.g., peer-to-peer)/ HD-TV / 3D / «

Per haps 10 folds in 5 yrs / 100 folds in 10 yrs

Sub-lambda switching with scalability to 10-100 Tb/s

on single switching matrix is needed




Challenges (Cont.)

Who will pay?When >90% of IP traffic is to home users

Given t

hat service providers

will not losemoney again «:

This may require major changes to:

IP network design ± lower complexity/cost

Services ± lower cost and easy to use

Applications

Business models




TechnologiesFocus on services on the end-user at home

Mobile and wireless are not the focus

Multi-terabit to the metro edges ±Sub-lambda ROADMs

±Optical burst and packet switching

±Time driven switching

±Multi-terabit IP routing and switching

±«

Very high capacity to the home ±Fiber-to-the-home: e.g., EPON, GE

±Twisted-pair-to-the-home: e.g.,VDSL2

±«




Services

Metro services ± Global IPTV /HDTV flooding: anywhere at anytime

±Triple-play services to the home

±Virtual reality services: gaming, meeting, conferencing, «

±Grid flooding applications

Content distribution ± ³on-demand´ toanyone, anything at anytime

±Content protection

±Storage location

±Capability matching with computation and trans-coding

±Scalable content delivery that matches end-user capability

Client operation complexity ±Matching the end-user software with content request




Summary

Testbed motivations: Internet ³flooding´with (home) users¶ ³on-demand´ requests:

Framework for global triple-any

Anyone/anything/anytime

Opportunities for new technologicalsolutions and new services

Real testing over 800 km optical network

Potential spin-offs and joint ventures

On-going testbed activities ± DIT Electronic lab

± Wide area with POLITO and POLIMI
