  2. Outline • P918, Motivation and Objectives • Optical Transport Network • IP backbone • IP over WDM, why ? • IP/ATM/SDH & WDM Layers • IP over WDM : First layering Network Scenarios • POL Packet Over Ligthwave: Cisco SRP and NTT MAPOS Concepts • Integration of IP over WDM: MPLS to control WDM • Standardisation : OIF Forum • Conclusion

  3. P918 Motivation • The exponential increase of IP traffic • The emerging of Giga-Tera bit Routers with STM-16/ STM-64 interfaces • The emerging of High bit rate Optical Network using OADM/OXC Network Elements • The need of simplified network scenario for IP over WDM

  4. P918 Objectives • To Provide an overview of Giga/Tera Bit Routers IP protocols RTP, Multicast, Diff Serv .. • To investigate different techniques to carry IP over WDM (new interface & protocol) • To identify different IP transport network scenarios assessing IP, ATM, SDH and WDM Inter-Networking • To contribute to standardization bodies IUT-T, ETSI, IETF and the new Optical Inter-networking Forum OIF

  5. Optical Transport Network : • 1995-1998: Point to point WDM (G.692) 4, 8, 16, 32 et 64? l à 2.5 et 10 Gbit/s OMux ODemux l1-ln Optical Amp. 640 Km OADM li
