2. 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. 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. 4 What is Carrier Ethernet? Question: –Is it a service, a network, or a technology? Answer for an end-user –Its a Service defined by 5 attributes Answer for a service provider –Its a set of certified network elements that connect to transport the services offered to the customer –Its a platform for value added services –A standardized service for all users

5. 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. 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. 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 Access to Cloud For Ethernet cloud carrier: Increase revenue with higher quality services incl.

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

9. 9 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 Flexible Service Interfaces FE/GE/10GE FE/GE/10GE DS3/OC3 Fiber Network OC3/12 n x T1 n x DS3 Bonded CU xDSL Cu TDM SONET Essential Components for Carrier Ethernet For Accelerated Service Delivery and Maximized Profitability

10. 10 Enables oversubscription by managing priority and congestion Provides tools to fix congestion issues reported by OAM Benefit: Enables end-to-end SLAs 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 Ethernet For Accelerated Service Delivery and Maximized Profitability

11. 11 Example: Dynamic Traffic Management Best Effort Service isnt 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. 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 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 Real Time Best Effort PSN RT EVC Headquarters UNI PE RT EVC Remote Branch Real Time Priority Data Best Effort Priority Data PE

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

14. 14 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,.. OPEX Reducing Tools Circuit Validation Fault detection Fault Analysis Fault correction Service Validation and Assurance Essential Components for Carrier Ethernet For Accelerated Service Delivery and Maximized Profitability

15. 15 EVC Real Time Best Effort UNI PSN EVC 1 EVC 2 Branch A Headquarters Real Time Priority Data Best Effort UNI PE EVC Branch B Real Time Priority Data Best Effort Priority Data Real Time Priority Data Best Effort IP DSLAM Traffic Generation and loopback per RFC-2544 Integrated RFC-2544 Generator 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 PE

16. 16 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 Monitoring & Mgmt.

18. 18 Accelerating Premium Carrier Ethernet Services Key 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. 19 Developing Premium Carrier Ethernet Services Conclusions 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 Demarc –Insist on scalable H/W OAM and powerful TM tools, but at no extra cost! 3.How can you reduce your on-going operations costs (TCO/OPEX)? –Minimize installation costs with automation and integrated turn-up testing –Slash support costs with proactive fault detection and correction –Manage network growth with efficient provisioning and PM tools
