1 Nortel Networks Confidential Content Over Optics (CO 2 ) “Optical services that turn on a dime to meet your needs” Franco Travostino Advanced Technology Nortel Networks Boston, MA

2 Nortel Networks Confidential Bandwidth is nothing without 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

3 Nortel Networks Confidential CO2 is a portable SW agent running on 3 rd 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 3 rd party can easily script CO2 to meet its own content needs Content Over Optics (CO2) Content Aware Optical Smart 3 rd party Service Enabling CO 2

4 Nortel Networks Confidential CO2 provides a usability shell around optical cores Optical Core CO2 Applications CO2: To increase and automate the exploitation of optical resources by applications. To integrate computation and communication end-to-end

5 Nortel Networks Confidential CO2 exploits ASTN agility ASTN Network Network EdgeNetwork Metro Access Network Servers Storage Servers Alteon UNI CO2 hosted by 3 rd party OPTera Connect OPTera Smart OS Smart Management System for OPTera UNI Storage UNI Servers 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)

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.

11 Nortel Networks Confidential Customer A Customer B OPECFG iSD NA/SA iSD CO2 Platform OM3500 Customer A Customer B OPECFG iSD NA/SA iSD CO2 Platform OM3500 CO2 Control Network Normal Traffic 10/100 CO2 Control Network CO2 MonitoredTraffic CO2 Control Traffic Metro BoD streaming media demo (CO2 internal milestone – Santa Clara, August ‘01) Media Server 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

12 Nortel Networks Confidential 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

13 Nortel Networks Confidential 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 …

14 Nortel Networks Confidential Example: lambdaCAD (CO2 meets Grids) visualization corridor Interactive 3D visualization 0.8 TB 1.7 TB 1.1 TB CO2 “LambdaCAD”—The 5 CO2 instances dynamically pool to negotiate BoD and diversity such that the various terabyte-scale datasets are all guarantee to start flowing into the visualization corridor (B) at the same time. The corridor only needs a modest circular buffer to stage incoming data awaiting processing Site C Headquarters Site B “LambdaCAD”—When the user starts a visualization session, the 5 CO2 instances dynamically pool to negotiate BoD and diversity such that the various terabyte-scale datasets are all guarantee to start flowing into the visualization corridor (B) at the same time. The corridor now only needs a modest circular buffer to stage incoming data awaiting processing (as opposed to requiring petabytes of local storage) When the user starts a visualization session, the 5 CO2 instances dynamically pool to negotiate BoD and diversity such that the large (TB+) databases can pump queried data (GB+) into the visualization “crunch” corridor (C) at times t0, t1, tn based on data inter-dependencies. The corridor only needs a circular buffer to stage incoming data awaiting processing (as opposed to petabytes of local, possibly outdated storage) Contractor X Site A dynamically provisioned tributaries to site B 4.2 TB
