Title: Efficient Backhauling Strategies for NGNs using Carrier-Ethernet
1Efficient Backhauling Strategies for NGNs using
Carrier-Ethernet
FORUM ON NEXT GENERATION STANDARDIZATION
(Colombo, Sri Lanka, 7-10 April 2009)
- SIVA RAMAMOORTHY,
- Group Director, Marketing
- Tejas Networks
2Agenda
- Emerging Bandwidth-demanding IP Services
- Establishing Transport Requirements
- Carrier-Ethernet Transport
3Emerging IP Applications
4Big Picture
5Carrier Challenges
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 ?

7Establishing requirements
Next-Generation Networks
Hierarchical QoS to distinguish between Control and Data traffic
Dynamic Protection (no user-defined work and protect paths)
Any-to-any connectivity with multicast-support
QoS for various traffic-profiles (Data, Voice, Video)
Statistical Multiplexing
Emergence of Data Services
Point-to-point connections from Access to Controller
Sub-50ms protection for voice
User-defined work and protect paths
Fast and automated Fault-detection and isolation
Conventional Telephony Services
8Which technology for backhaul?
Carrier-Ethernet
Hierarchical QoS to distinguish between Control and Data traffic
Dynamic Protection (no user-defined work and protect paths)
Any-to-any connectivity with multicast-support
Hierarchy is built-in
PBBERPS for connection-less protection, Shortest Path Bridging
Fundamental feature of Ethernet
Natively provided through 802.1p
Fundamental feature of Ethernet
Traffic-Engineered (user-defined) point-to-point connections through PBB-TE
IEEE G.8031 and G.8032 for Sub-50ms protection
Option for NMS-provisioned paths
IEEE and ITU-T CFM-OAM, EthOAM, EFM-OAM
QoS for various traffic-profiles (Data, Voice, Video)
Statistical Multiplexing
Point-to-point connections from Access to Controller
Sub-50ms protection for voice
User-defined work and protect paths
Fast and automated Fault-detection and isolation
9Summary
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
