What is the Transport?
Carrier Challenges
Transport
Capacity
Time
How to Cope up with the growth in backhaul bandwidth requirements ?
What is the best way to transport ?
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 ?

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