3. WP5 meeting, 09.02.2005 ParisSummary Technical Audit WP5: 11:30 – 12:00 PMD compensation (new concepts ?), explained PLABS approach Advanced OPM, what can be expected ? Answer: e.g. reference receiver / eye opening / margin extraction Amplifier transients switching (in case of failure) Simualtion tool for dynamic networks ? No envisaged, however publications will inform about suggested process General questions: D13 rated technically high, too many cost studies Patents issued / Standards ? / Dissimination in books ? (xxx) Sharing of public information with other projects ? (e.g. ePhoton) Evaluation of project risks: regular conference calls. Should OBS being supported in a separate project, not being late with this new technology Evaluations List of Acronyms, unified structure like use spell-checker !!! Main part + appendices Discussion: Mainly physical layer experts OPM & PCAG & CSG activities where recognized as important Showed Audit slides + meeting notes „Put‘s us somehow in the spotlight“ Dissimination in books  Alexandros Stavdas will take care and make a proposal

4. Group Readout CSG: Andrew (slides) Team: Martin Wade, Sofie Verbrugge, Sandrine Pasqualini, Marco Quagliotti(WP2) Objectives: as defined in document „Proposal_costcomparison_issue1.doc“ Presentation: Time line might be too short to get the tools, which can optimize the network wrt cost. However, this would be required. Solver for linear programming - WRA - Physical layer constraints • Cost • Blocking probability, • (Infinera / Polatis / Lambda Optical Systems) PCAG: Dominic (slides) Team: Chris Matrakidis, Matthias Gunkel Objectives: to be defined in Paris Presentation: Iterative process: Network dimensioning -- capacities -> connection set-up calculation –load distribution - OTN nomenclature • Timing requirements • Algorithms • Performance measures (blocking / utilisation, number of entities used)

5. Group Readout – cont‘d Tanya Politi (slides) • Physical Impairment Aware WRA, dynamic traffic (T. Politi) • Calculate blocking probability • Wavelengths assignment flow chart, various layers (different levels of accuracy) • Discussion on technical details (what should be simulated) Shall network dimensioning (equipment placement) in D19 be based on static traffic demand using a wavelength assignment algorithm ?? Current assumption: NO

6. Joint meeting 1/2/5/7, Feb 9th, 9:15-10:05 CSG WP2/5/7: presentation from Andrew L. O-E-O vs. transparencyComment: Look for common cost model in NOBEL S. Bodamer: WP2 tool only relative cost included, would join the team D15: Case study for optical transparency: connect teams Other case studies to be reviewed interest ??? Reference networks (German network) Availability work may also be of interest Team discussion: Andrew (Stefan B.) internal tool for eq. placement, and comparison of different switching levels WDM Guru / cannot be updated for specific devices required for OPM Marco (TI): Has info on TI network internal tool Jan (??): stay with a consistent cost model Sophie (IMEC): internal tool

7. Joint meeting 4/5 (OPM), Feb 10th 11:00-11:30 CTTC presentation on OPM: No standards on OPM / QoS / transparent analogue measures ITU-T G.697 Add BER / packet loss / delay CTTC approach covers Pre-qualifying optical links On-line measurements (accurate enough ?) Fault management and resilience !!!!! OSNR measurement / Q factor est. / reference receiver What about potential separation of PMD/ CD / non-linearities ? Finalize document: Conclusion sections Actions for WP5: Define concatenation rules to transform link performance metric into path performance for path computation

8. CSG meeting 2/5/7 10-11h Looking for a procedure Sub-wavelength switching may be required for overall optimisation (Bodamer) David results ?? (Alcatel, SDH vs. RPR) Given: Reference network & traffic Dimensioning a network • Simple • Protection • Physical layer Objective / metric ? (capacity x length) Alex WP5 12-13h readout CSG Tools for equipment placement ? Marco/Sophie can perform this task Then cost can be assigned using Jan xx cost model from A2.3 PCAG: Can start with dynamic traffic on network solution provided from Marco/Sophie Dominic will start working with the team

9. D19 meeting 14-16:30h • TS - PMD matrix varies over time, residual GVD distribution • Lucent DML /duobinary comparison for Metro networkNeed Q factor !!! / legend has to be exact • PMD ? • ACREO Network design (based on ref. Netw topology)need Lucent / Siemens input • Include static traffic matrix in D19 ? • Matthias‘ wavelength assignment algorithm • D26 dynamic traffic

10. WP5 Wrap up, Feb 10th D19: • Final presentations (Erwan, experimental results for NRZ/RZ/ODB @ 40Gb/s) • Henning (CD&PMD), Pirelli contribution to be added • Optical performance is given in Q margin (after FEC) for the three ref. netw. • No traffic distribution • Simple Q margin analysis for reference networks • PMD (time-dependency?) is still a topic to be included in the design process (flow chart ????) D26: • Static traffic distribution to start with (by Matthias) • Dynamic traffic demands • Simplified Q factor calculation required (see Tanya‘s slides) • Real time processing of route calculation (network operation) CSG: Andrew Send slides to WP5 PCAG: Dominic Send slides to WP5 Conclusion on „Quo Vadis“ discussion achieved ? NO !

12. Schedule for D19 (M15), Lead: Andrew, BT Coordinate with deliverable D13 • First TOC (and bullet items list), Andrew Oct 04 • Face-to-face meeting (NBG) 7./8. October • Define links to D13, align contributions from partnersContinue to support design rules, organize „supplier‘s group“ ? • Agree on reference network for simulations & metrics for comparison, would involve economics, hard to be covered in WP5 • Traffic distribution and dynamics required Organize a „carrier‘s group“ (Andrew) • Initiate „path calculation algorithms group“ (Dominic) • Discuss first results and define further work mid of December • First draft (D19), before Christmas • All results by end of February • Finalize document end of March We are here Detailed schedule on next slide
