Agenda
• Carrier Ethernet Defined• Key Drivers for Carrier Ethernet• Carrier Ethernet Market Segments• Accelerating Service Delivery and Maximizing Profitability
– Essential Components– Key Questions– Answers & Conclusions
3
Carrier Ethernet Defined
• The MEF has defined Carrier Ethernet as: A ubiquitous, standardized, carrier-class
Service and Network defined by five attributes that distinguish it from familiar LAN based Ethernet.
Carrier Ethernet for the Business Users:
Carrier Ethernet for Service Providers: • A set of certified network elements that connect to transport
Carrier Ethernet services for all users, locally & worldwide.• Carrier Ethernet services are carried over physical Ethernet
networks and other legacy transport technologies.
4
What is Carrier Ethernet?
• Question:– “Is it a service, a network, or a technology?”
• Answer for an end-user– It’s a Service defined by 5 attributes
• Answer for a service provider – It’s a set of certified network elements that connect
to transport the services offered to the customer– It’s a platform for value added services– A standardized service for all users
5
Key Drivers for Carrier Ethernet
TCO as a driver for operator decisions
Flat revenues + Exponentially increasing BW = Cost pressure
Forces operators to look for new revenues based on dynamic QoS and SLA
Premium Carrier Ethernet Demarcation Equipment is required
6
Carrier Ethernet Market Segments
Retail Business services• Inter office connectivity, Internet access, VoIP, Server
Consolidation, Distributed Imaging, Disaster Recovery,…• Finance, Healthcare, Education, Government, etc…
Wholesale services• Transport services for service providers• E-NNI, Ethernet Exchanges, etc…
Mobile Backhaul - Wholesale/Internal• Wholesale backhaul of 2G, 3G, 2G+3G Services• Mobile Operator testing and extending own
networks
7
Additional Carrier Ethernet Markets
Access to Cloud • For Ethernet cloud carrier:
Increase revenue with higher quality services incl. SLA• For Cloud Consumer (Enterprise IT):
Reduce costs by controlling resources / Security Improve QoE with predictable SLAs
Ethernet Exchanges• SLA Monitoring helps standardize service offering
across multiple carrier footprints
Enterprise WAN QoS• Optimize WAN performance and accelerate
applications with zero-latency traffic shaping• Monitor retail carrier’s SLA to ensure compliance.

• Enables oversubscription by managing priority and congestion• Provides tools to fix congestion issues reported by OAM• Benefit: Enables end-to-end SLA’s over any network• Benefit: Offer premium services at premium prices
TM Tools• CoS classification• Policing• P-bit remarking• Hierarchical Scheduling• Per EVC Shaping
Traffic Management
Essential Components for Carrier EthernetFor Accelerated Service Delivery and Maximized Profitability
11
Example: Dynamic Traffic Management
Best Effort Service isn’t always Pretty
“Fast lane” Solution:• Move from Best effort service to a tiered CoS• Tariff is dynamic (higher during peak hours to throttle
traffic and guarantee SLA for those drivers willing to pay)
12
Traffic Management at Customer Demarc Adds tools to Optimize and Accelerate Traffic Performance
Traffic Management Tools conform traffic to BW profiles and ensure End-to-End SLA on a per service basis:Ensures higher priority traffic is served first and not droppedIncreases usable bandwidth by delaying non real-time packets.Shapes traffic at customer premises to avoid overflowing downstream or
upstream network elementsEnsures scheduling “fairness” and better network load distribution

Connecting Communities -QoS and SLA for Rural Broadband
Broadband connection to remote communities• 20% Caribbean Population is considered Rural (out of reach).• Unlicensed Wireless Connections is a effective
solution that can provide High capacity Ethernet per sector– 200 Mbps aggregate throughput– Up to 16 SUs per sector
• Guaranteed SLA and capacity per SU• Small and constant latency

Accelerating Premium Carrier Ethernet ServicesKey Questions
1. How can you accelerate your Premium Carrier Class services?2. How do you minimize TCO/CAPEX without compromising on
Features/Quality?3. How do you reduce your on-going operations costs (TCO/OPEX)?
The Key is to Select the Right Carrier Ethernet Platform
19
Developing Premium Carrier Ethernet ServicesConclusions
1. How can you accelerate your Premium Carrier Class service?Implement Traffic Management tools and SLA Guarantees accurately and
consistently, irrespective of access networks
2. How do you minimize TCO/CAPEX?Reduce inventory expenses and TTM by deploying modular DemarcInsist on scalable H/W OAM and powerful TM tools, but at no extra cost!
