  1. NOBEL WP2.1 Meeting Paris, 8-10.02.2005 ToC D27 Resilience & Joint Paper Proposals NOBEL WP2.1 Meeting, Munich,3December 2004

  2. Structure of Work in A2.1 for D27 • D27: Main part of deliverable: Description of innovative Results of case studies on MMM TE and Resilience • Annex: Internal reports with description of case studies, prepared/submitted/accepted publications in journals / conferences / workshops • Technical Approach • Start work on different topics in small groups (task forces) • Perform joint theoretical studies and simulation case studies • Prepare joint publications and (more detailed) internal reports • Paste publications / internal documents to annex of D27 • Prepare integrated document which highlights main innovations, results and NOBEL resilience guidelines with references to detailed case studies in annex (M20 - M22) NOBEL WP2.1 Meeting, Munich,3December 2004

  3. A2.1 Study Groups D27 Resilience ToC / Definition of Study Groups • 1. Overview and Classification (incl. QoR) • 2. Advanced Resilience (incl. Efficient Resource Sharing) • 3. MultiLayer (& Multiservice) • 4. MultiDomain (& MultiLayer (& MultiService)) • 5. NOBEL View on Resilience NOBEL WP2.1 Meeting, Munich,3December 2004

  4. Study Group QoR (Multiservice Resilience?) • 1. Overview and Classification • General • Definitions and Classificiation (IMEC) • Classification of Prot. & Rest. (Marconi) • On Sharing Resoursces • SRG (SRLG) • MultiLayer • Sharing not only between demands, but also between QoS, QoR classes • Multiservice Resilience: QoR Definition • Relation to Service Classes (to QoS as well) • Using QoR (AGH) • Partners: TILab, AGH, BUTE, Marconi (, IMEC) • Responsible Partner: AGH • Additional reference: Achim Autenrieth, „Recovery Time Analysis of Differentiated Resilience in MPLS“, DRCN 2003 NOBEL WP2.1 Meeting, Munich,3December 2004

  5. Study Group Advanced Resilience • 2. Advanced Resilience through Efficient Resource Sharing • “SingleLayer SingleDomain, but General (of interest for GMPLS/ASTN, ML, MD, etc...)” • Resilience Schemes • Fast ReRoute, MRDV (TID) • P-cycle (AGH (ML), BUTE (MD), (Siemens (Dominic))) • MultiPath (TID, Lucent) • SharedProt (BUTE, Ericsson, Marconi, Siemens) • Availability Studies (T-Systems) • perhaps move availability studies to other SGs • Partners: Lucent, Marconi, TID, T-Systems, AGH, BUTE, Ericsson • Responsible Partner: TID NOBEL WP2.1 Meeting, Munich,3December 2004

  6. Study Group Multilayer Resilience • 3. MultiLayer • Conceptual Studies • FT (abstract ML model (G.805)), T-Systems ? (Availability studies), Telenor (?) • Applied Models • Introduction • Overlay & Augmented (Alcatel, Siemens, T-Systems, Ericsson, AGH, UPC) • IPoTransport (Marconi?) • RPR-MPLS and RPR-OTN (GMPLS) interactions (AGH, UPC) • Augmented (FT(MultiService) Siemens) • Peer (Marconi, BUTE) • MultiService (MultiLayer) • WP1 defines Services D6 • Partners: Siemens, FT, Telenor, Ericsson • Partners: nearly all! • Responsible Partner: Siemens NOBEL WP2.1 Meeting, Munich,3December 2004

  7. Study Group Multidomain Resilience • 4. MultiDomain (& MultiLayer (& MultiService)) • SingleLayer • MultiLayer • MultiService • Partners: IMEC, BUTE, Ericsson, (UPC) • Responsible Partner: Ericsson Contribution from BUTE • Impact of flooding method onto routing and protection • Impact of number and size of domains onto routing and protection • Routing and protectionwith Game Theory NOBEL WP2.1 Meeting, Munich,3December 2004

  8. Resilience in MMMM Nets: Changed ToC • 5. NOBEL View on Resilience • Responsible Partner: NOBEL WP2.1 Meeting, Munich,3December 2004

  9. Partners Contributions Snapshot; latest data in excel spreadsheet (A21_study_groups) NOBEL WP2.1 Meeting, Munich,3December 2004

  10. Work planned in Y2 • Partners in each SG agree on studied concepts, reference networks, network models, traffic models, simulation tools, etc. (Jan./Feb. 05) • Each Study Group prepares a short internal document / presentation describing their concepts and intended case studies (2 to 5 pages / slides) (Feb. 05) • SG perform their studies and evaluate the concepts (Feb. to Jul. 05) • Goal of each SG should be joint publication(s) to a journal or conference (e.g. DRCN 2005) (May to Aug. 05) • Results of case studies, internal documents and publications are prepared until Aug. 05 and added to Annex of D27 • Key results and general guidelines derived from the TE and resilience case studies are presented in main part of deliverable (Sep./Oct. 05) NOBEL WP2.1 Meeting, Munich,3December 2004

  11. Results • Study Groups • Advanced Resilience • Multiservice Resilience • Multilayer Resilience • Multidomain Resilience • Responsible partners for study groups • Proposals for joint papers on • Multiservice Resilience • Multilayer resilience NOBEL WP2.1 Meeting, Munich,3December 2004

  12. Open issues • Should QoR be renamed to Multiservice Resilience • Updated proposal for ToC NOBEL WP2.1 Meeting, Munich,3December 2004

  13. Proposals for Joints Publications • Overview paper (CommMag, IEEE Networks Magazine) • NOBEL view on resilience topics, mechanisms, … • NOBEL Resource efficient resilience using resorce sharing (technology and evaluation paper) (Siemens) • BUTE, Ericsson, Marconi, Siemens, … • single layer, SRG / SRLG, multilayer • static and dynamic traffic scenarios • case studies on cost vs. availability evaluation (BUTE) • NOBEL Multiservice resilience (positioning paper and case studies) (AGH) • „How does NOBEL deal with multiservice resilience aspects?“ • QoR definition, Routing algoriths to meet QoR constraints, resilience mechanisms considering multiple services and resilience requirements, resource sharing between service classes • NOBEL Multidomain resilience (positioning paper and case studies) – (BUTE) • „How doe s NOBEL deal with multidomain resilience aspects?“ • BUTE case study: Distributed survivable routing for single- and multidomain shared resilience NOBEL WP2.1 Meeting, Munich,3December 2004

  14. IMEC: Proposal for Joints Publications (cont‘d) • Technology oriented papers (targeted towards standardization) • RSVP-TE extensions for resilience (e.g. PPRO for multidomain resilience) • RPR, multilayer RPR (AGH, UPC, Siemens?) • Multilayer p-cycle (AGH) • Availability studies (T-Systems) • Cost and availability model and reference data (Marconi, T-Systems, IMEC, Siemens, Telenor) • comparision of different available technologies (swot analysis and comparison of several technologies) • DRCN Tutorial on NOBEL Resilience vision (IMEC) (Tutorial chair: Giuseppe Ferraris; NOBEL WP2.1 Meeting, Munich,3December 2004
