2. 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 Carrier Ethernet for the Business Users: • 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 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

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.

8. Essential Components for Carrier EthernetFor Accelerated Service Delivery and Maximized Profitability Flexible Service Interfaces Traffic Management • TM Tools • CoSclassification • Policing • P-bit remarking • Hierarchical Scheduling • Per EVC Shaping Service Validation and Assurance • OPEX Reducing Tools • Circuit Validation • Fault detection • Fault Analysis • Fault correction Service Monitoring • Monitoring & Mgmt. • Hardware based OAM • Statistics collection • SLA threshold alerts • SLA Exception reports • PM Portal

9. Essential Components for Carrier EthernetFor Accelerated Service Delivery and Maximized Profitability Flexible Service Interfaces • Scalable bandwidth (nxT1/DS3, 10/100, nxOC-3/12, GE, 10GE) • Service Flexibility (EoCU/TDM/SONET, Pseudowire & Timing) • SFP/UTP Combo ports, • Benefit: One platform to deploy for all access types and services • Benefit: Reduces inventory requirements • Benefit: Uniform service delivery and SLA management FE/GE/10GEDS3/OC3 FE/GE/10GE Bonded CUxDSL Cu Network Fiber n x T1n x DS3 TDM OC3/12 SONET

10. Essential Components for Carrier EthernetFor Accelerated Service Delivery and Maximized Profitability Traffic Management • 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 • CoSclassification • Policing • P-bit remarking • Hierarchical Scheduling • Per EVC Shaping

11. Example: Dynamic Traffic Management • “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) Best Effort Service isn’t always Pretty

12. 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 dropped Increases usable bandwidth by delaying non real-time packets. Shapes traffic at customer premises to avoid overflowing downstream or upstream network elements Ensures scheduling “fairness” and better network load distribution Traffic Management at Customer Demarc Adds tools to Optimize and Accelerate Traffic Performance Headquarters Real Time PE Priority Data BE EVC PSN Best Effort Remote Branch RT EVC Real Time PE RT EVC Priority Data BE EVC Best Effort UNI

13. 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 SU SU BS BS BS SU SU Service Provider Network SU SU SU Service Provider Premises

14. Essential Components for Carrier EthernetFor Accelerated Service Delivery and Maximized Profitability • Circuit Validation (RFC-2544, Y.1564, MAC/IP Swap loopbacks) • OAM helps detect and isolate faults and take corrective action • Benefit: Proactive testing improves response times • Benefit: Hardware OAM tools reduces OPEX (less truck rolls) • Benefit: Fault propagation, EVC redundancy, ring redundancy,.. Service Validation and Assurance • OPEX Reducing Tools • Circuit Validation • Fault detection • Fault Analysis • Fault correction

15. Integrated RFC-2544 Generator Traffic Generation and loopback per RFC-2544 Branch A • Create a “birth certificate” at service turn-up • Provide customer with report before service starts • Confirm troubleshooting has succeeded • Automatic periodic testing for: Preventive maintenance & capacity planning Real Time Headquarters PE UNI EVC Priority Data Best Effort Real Time PE Priority Data EVC 1 PSN Best Effort Branch B EVC 2 Real Time IP DSLAM Real Time EVC Priority Data Priority Data Best Effort Best Effort UNI

16. Essential Components for Carrier EthernetFor Accelerated Service Delivery and Maximized Profitability • Measure latency, jitter, packet loss and availability • Identify network degradation and congestion points • Benefit: Defend SLA with accurate Hardware based OAM • Benefit: Efficiently manage bandwidth growth Service Monitoring • Monitoring & Mgmt. • Hardware based OAM • Statistics collection • SLA threshold alerts • SLA Exception reports • PM Portal

17. Service Monitoring -Customized Web Portals with Reports/Dashboards
