Bandwidth is nothingwithout control

The Wright Brothers had plenty thrust. Their problem was how to control it

Likewise, we have plenty bandwidth. We must now devise ways to harness it, and expose proper value props, where and when they are needed


• CO2 is a portable SW agent running on 3rd party end-systems or L2-L7 switches. It feeds bandwidth and services to applications while exploiting agility in dynamic optical networks (ASTN, Metro/ASTN, RPR)—e.g. BoD for backups

• CO2 enables just-in-time and custom bandwidth management, client-operated optical VPNs, SLA monitoring and verification, pricing, error notification, diversity formulations, resource defragmentation …

• With CO2, carriers and service providers gain access to higher revenues, distinguishing features, and lower op-ex. A 3rd party can easily script CO2 to meet its own content needs

CO2 in Nortel L2-L7 switch

In this setup, optical services over ASTN supply BoD for high-volume, strict-guarantees traffic between data centers (backup), or in/out of storage service providers (e.g. storage on demand for flash crowds)

CO2 also exploits RPR agility

This BoD setup over RPR (with 1Mb/s increments) is ideally suited to streaming media and synchronous mirroring over Metro distances

(the CO2 agent is hosted on Alteons attached to OM3x00)


• Exploit diverse forms of optical agility– Models: Overlay, Hybrid– Technologies: ASTN, Metro ASTN, RPR– Different feature sets apply depending on optical technology of choice

• Smart Bandwidth Management– Policy Based Bandwidth on Demand– Advanced Scheduling/Reservation

• Client Managed Optical VPN

• Layer x <-> Layer 1 Inter-working– Cut through Lightpath– L3 to L1 QoS mapping

• Alternate Site Failover

• 3rd party service creation and installment

• OAM&P Features – SLA Monitoring and Verification– Crypto-strong Peer Authentication– Service Discovery– Logical Link Commissioning– Error Notification

• Before movies are out … post-production houses exchange master tracks. E.g., 30’ of “Moulin Rouge” movie amount to 2 terabytes, with a handful of post-production houses involved for special effects

• After movies are out … by 2005, 26% of box-office receipts will come from digital showings. Source: Forrester (Mar, 2001)

Toward Digital Movies CO2 negotiates a LH optical trail meeting the requirements set (e.g., based on cost, RAID throughput, availability)

Metro BoD streaming media demo (CO2 internal milestone – Santa Clara, August ‘01)

Alteon identifies new content matching a given pattern. On Customer A’s behalf it will negotiate a higher SLA with the RPR ring if it’s still within its monthly allowance

Applications and end-systems run unmodified


• We’re realizing CO2-enabled storage scenarios in partnership with a major storage vendor

– CO2 hosted on the vendor’s equipment– BoD prototype in 2Q02– Comprehensive CO2 feature set in 4Q02

• In parallel, we bring new streaming media features into CO2– CO2 hosted on Alteons– CO2 control program clones and fans out content to local subscribers, optional

mid-span content insertion– Out-of-band/In-band triggers into RPR signalling– Content transforms according to route (e.g., over IP, RPR1or RPR2)– 3rd party secure service creation toolkit for CO2

• Standards– We are actively contributing to UNI 2.0 at the OIF

• We’re interested in research partnerships– Disaster protection, grids, research networks

CO2 is well on its way


• Ways we can harness UNI-speaking switched optical networks ASAP

– OmniNet?, StarLight?

• New application scenarios using CO2-based services– Possibly in Grand Challenges, Terascale scale– Ideally, high payback and feedback potential for CO2

• Any interest in the application scenarios we’ve worked on– Primarily storage related

• Sessions involving n CO2 agents, n > 2– Globus picks up where the CO2 stack stops …– Collaborative idea: CO2 agents gang-schedule resources on a grid– Another collaborative idea: CO2 agents engage in a secondary market for

lambda trading

• Policy aspects in CO2– For pricing, de-fragmentation, AAA

We wish to discuss …
