Efficient Carrier Ethernet Strategies for Next Generation Network Backhaul

This presentation by Siva Ramamoorthy, Group Director of Marketing at Tejas Networks, addresses the crucial topic of backhauling strategies in the context of next-generation networks (NGNs). With the increasing demand for bandwidth due to emerging IP services like mobile TV, IPTV, and online gaming, it is important to establish effective transport requirements using Carrier Ethernet. The discussion includes transport technologies, managing capacity, providing stringent SLAs, and optimizing capex and opex. The insights focus on the future evolution of data services and solutions to ensure efficient network performance and reliability.

  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
