  1. FORUM ON NEXT GENERATION STANDARDIZATION (Colombo, Sri Lanka, 7-10 April 2009) Efficient Backhauling Strategies for NGNs using Carrier-Ethernet SIVA RAMAMOORTHY, Group Director, Marketing Tejas Networks

  2. Agenda Emerging Bandwidth-demanding IP Services Establishing Transport Requirements Carrier-Ethernet Transport

  3. Emerging IP Applications

  4. Big Picture 2G/2.5G WIRELESS BACKHAUL MOBILE TV/ APPLICATIONS BTS 3G WIRELESS BACKHAUL ? IPTV CABLE DSLAM INCREASING BROADBAND INTERNET BASE – YouTube, Video-on-demand applications etc. What is the Transport? ONLINE GAMING ENTERPRISE NETWORK ELAN, VOICE ETC.

  5. Carrier Challenges Transport Capacity How to Cope up with the growth in backhaul bandwidth requirements ? What is the best way to transport ? Time How do I provide more stringent SLA, Fault Management, Performance Monitoring and demarcation to Enterprise customers ? Should I have single infrastructure for residential and business customers ? How do I keep the cost (CAPEX and OPEX) under check ?

  6. Transport Technologies Trends 100% Data Carrier-Ethernet over Fiber (With Synchronization With Circuit-emulation) Carrier-Ethernet over Fiber Carrier-Ethernet over NG-SDH Carrier-Ethernet over NG-SDH Ethernet over NG-SDH ATM over SDH Legacy SDH 100% Voice Legacy PTT Basic Data over conventional Networks Next-Generation Networks Future Evolution

  7. Establishing requirements Next-Generation Networks Emergence of Data Services Conventional Telephony Services

  8. Which technology for backhaul? Carrier-Ethernet

  9. Summary SDH/SONET Legacy Ethernet provisioned circuits 50-ms protection No OAM, no Traffic-engineering Flat network bandwidth efficiency (sharing) Bandwidth in-efficient Carrier-Ethernet Transport Bandwidth efficient Carrier-grade OAM Sub-50ms protected P-to-P and MP-to-MP Carrier-Ethernet Transport for NGN Backhaul • Sophisticated Carrier grade Ethernet transport solution • Carrier grade management and reliability • Evolve gracefully, keep revenues ahead of costs • Lower Operations and training costs
