This service has been popular over the past few years and in parallel there has been an increasing interest in scalable, end-to-end Ethernet services. Several developments in the area of VPNs have helped to enable Ethernet-based VPNs. Chief among these are two MPLS technologies: Virtual Leased Line (VLL) and Virtual Private LAN Service (VPLS). Virtual Leased Line (VLL or E-Line), also known as Ethernet Point-to-Point VPN service, emulates the behavior of a leased line between two points. In the industry, this technology is also referred to as Virtual Private Wire Service (VPWS) or Ethernet over MPLS (EoMPLS). VLLs use the pseudo-wire encapsulation for transporting Ethernet trafc over an MPLS tunnel across an IP/MPLS network. Virtual Private LAN Service (VPLS or E-LAN), also known as Ethernet Multipoint-to-Multipoint VPN service, emulates the behavior of a traditional bridge between multiple points. Ethernet Point-to-Multipoint VPN service can be considered as a special case of Ethernet Multipoint-to-Multipoint VPN Service with one site designated as the Hub connected to multiple points.Service providers can use these technologies to offer advanced services to their customers such as managed VPN services. Similarly, large enterprises can use these technologies to virtually segment their networks based on business needs, and across geographical boundaries.Advantages of Ethernet VPN services: Offers easy, scalable growth that can be quickly upgraded Offers very high bandwidth WAN connections Delivers more bandwidth for the money than other data servicesWhite Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 5 Provide QoS / CoS options for various voice, video and data applications Eliminates the need for expensive WAN interfaces Allows better utilization of bandwidth Provides protocol transparency Provides secure connection between two or more sitesStandard Product Features Ethernet VPN Topology Options (See Figure 2: VPN Topologies)Connect two locations; Point-to-Point VPN Connect a hub to multiple remote locations; Point-to-Multipoint VPNConnect multiple locations to each other; Multipoint-to-Multipoint VPN Native Ethernet (MTU frame size set to 1546 bytes) Dedicated full-duplex MAC addressesNo limit on Point-to-Point topologies250 limit on multipoint topologies Access via 10/100 Mbps or 1000 Mbps Committed Information Rates (CIR) per site as follows:10-100Mbps in 10 Mbps increments (10/100Mbps port)100-500Mbps in 50Mbps increments & 500-1000Mbps in 100Mbps increments (1000Mbps port)2 to 8 x 1000Mbps in 1000Mbps increments (LAG 1000Mbps ports) (VPLS only)Port Media and Physical Interfaces: 100BaseTX; Cat5e (100m)100BaseFX; LC Connector; SMF (2km) 1000BaseTX; CAT5e (100m)1000BaseSX; LC Connector; MMF (500m)1000BaseLX; LC Connector; SMF (2km) Protected and diversied MPLS Core/Edge Network (ber, equipment, power) Performance (applies to CIR trafc only)Latency (round-trip delay) 5ms Metro 20ms inter-Metro 30ms Inter-StateJitter 5msPacket Delivery 99.95% Network Availability* 99.995%* Some customer sites may require Protection feature in order to achieve this level of network availabilityWhite Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 6Value Added Features Protection Jumbo Frame support, with MTU set to 9000 bytes (available only with1000Mbps ports) VLAN option for additional services through the same physical port Port Upgrade: 100 to 1000Mbps (for CIR < 100Mbps) Quality of Service allows the ability to prioritize trafc Bursting for trafc above CIR (best effort) Multicasting (up to CIR) Other customized solutions available upon request** Development times and charges may applyNotes:Point-to-Point Ethernet VPNBoth A and Z locations must have same CIR (and PIR)Point-to-Multipoint Ethernet VPN CIR set per site, however, service quality not guaranteed unless CIRHub CIROther SitesQuality of Service feature highly recommended if CIRHub CIROther Sites Multipoint-to-Multipoint Ethernet VPNCIR set per site, however, service quality not guaranteed if trafc exceeds locations CIRQuality of Service feature highly recommended for this type of serviceFig. 2: VPN TopologiesFPL FiberNetsIP/MPLS/EthernetnetworkFPL FiberNetsIP/MPLS/EthernetnetworkCustomerlocation(remote ofce)Customerlocation(headquarters)Customerlocation(headquarters)Customerlocation(remote ofce)Customerlocation(remote ofce)Customerlocation(remote ofce)Customerlocation(remote ofce)Customer premise equipmentEthernet multipoint-to-multipoint VPN Ethernet point-to-multipoint VPNEthernet point-to-point VPNFPL FiberNet Ethernet equipment10, 100, 1000 Mb/sEthernet connectionCustomerlocation(remote ofce)FPL FiberNetsIP/MPLS/EthernetnetworkWhite Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 7Value Added Features in DetailProtectionThe standard Ethernet VPN service may be provided over local infrastructure without ber or route diversity between Provider Edge (PE) equipment to Customer Edge (CE) equipment or Network Interface Device (NID);Fig. 3: Unprotected Fiber InfrastructureProtected and diversiedMPLS network: ber,power and equipmentPE CE NIDCAT5e/MMF/SMF handoffCAT5eRiser EntranceLocal berinfrastructureCustomerpremiseUnprotected ber/routeUnprotected ber/routeProtected and diversiedMPLS network: ber,power and equipmentPE NIDCAT5e/MMF/SMF handoffIf available, ber and route diversity can be provided as a value added feature to the Customer Premise equipment.

As a value added feature, multiple services can be delivered to a customer at a single location through the same physical port. This feature requires that services be tagged at the location with different VLAN tags so that trafc can be separated by the customer and FPL FiberNet.White Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 9Fig. 6: Service Multiplexing using VLANLocal networkproviding access fromFN to customerPE Customer equipmentBoth servicesprovided over samephysical portVLAN200 =dedicated Internet accessVLAN100 =Ethernet point-to-point VPNNID NID PE Customer equipmentMulticastingThe standard Ethernet VPN service has limited (1 Mbps) multicasting bandwidth. As a value added feature, multicasting can be supported. This feature may enable customers to multicast up to CIR.Note: This feature is only applicable to Point-to-Multipoint and Multipoint-to-Multipoint VPNsBurstingBursting bandwidth is available at best-effort quality up to port speed (100Mbps or 1000Mbps). Since bursting is best-effort, overall service quality may degrade during periods of bursting if critical packets are not able to meet required SLAs (i.e. delay, jitter, loss packets, etc.). To mitigate this effect, customers can prioritize their trafc using Quality of Service feature described in the next section or below. Quality of Service The standard Ethernet VPN service provides for the highest quality of service for the Committed Information Rate (CIR). However, different types of trafc require different service require ments.Note: Standard Product Performance SLAs may not be met for Latency and Packet Delivery if QoS is selected and service experiences congestion.Voice Minimal end-to-end delayMinimal jitterMinimal packet lossExpediteTrafc type or category Service requirement Suggested priority levelVideo Reasonable end-to-end delayMinimal jitterMinimal packet lossHigh priorityPreferred data Reasonable end-to-end delayReasonable jitterNo packet lossLow priorityBest-effort dataFor Routing Protocol or Network Control suggested classication would be CoS3.No delay constraintsNo packet lossBest effortCoS1Suggested classicationCoS1 or CoS2CoS3 or CoS4CoS5 or CoS6White Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 10CoS1 Interactive voice/interactive videoDelay sensitiveapplications (video)EFAF41ClassicationCoS ClassicationIntended application PHBCoS2CoS1, CoS2, CoS3 trafc strictly policed/prioritized with excess trafc droppedCoS4, CoS5, CoS6 bandwidth sharing calcualted based on BW allocation(Within each trafc classifation in-contract trafc is favored over out-of-contract trafc)46DSCP34CS5Class selectorCS45802.1p class selection4Routing protocolnetwork controlNC1NC2CoS3 4856CS6CS76Scavengernon-critical trafcAF11 (in-contract)AF12 (out-contract)CoS6 1012CS1 1Bursty trafc AF31 (in-contract)AF32 (out-contract)AF21 (in-contract)AF22 (out-contract)CoS4 26281820CS3CS232Best effort BE CoS5 0 CS0 0Multimedia 10-100 by 10100-500 by 50500-1000 by 1005-20% by 5%30-90% by 10%QoS proleFPL FIberNet Ethernet VPN CoS Prole Bandwidth Allocation TableCIR bandwidthavailability (Mb/s) CoS15-20% by 5%30-90% by 10%CoS25-30% by 5%30-90% by 10%CoS35-30% by 5%30-90% by 10%CoS45-30% by 5%30-90% by 10%CoS50-20% by 5%20% 10% 5% 35% 25% 5%CoS6Criticaldata10-100 by 10100-500 by 50500-1000 by 100N/A N/A 5-30% by 5%30-90% by 10%5-30% by 5%30-90% by 10%5-30% by 5%30-90% by 10%N/AN/A N/A 100% 0% 0% N/AN/A N/A 80% 10% 10% N/AN/A N/A 60% 30% 10% N/AN/A N/A 40% 30% 30% N/ABusinessdata10-100 by 10100-500 by 50500-1000 by 100N/A N/A N/A 100% 0% N/AN/A N/A N/A 90% 10% N/AN/AStandarddata10-100 by 10100-500 by 50500-1000 by 100N/A N/A N/A 100% 0% N/AN/A N/A 50% 50% N/A*CoS1, CoS2, CoS3 trafc strictly policed/prioritized with excess trafc dropped**BW percentage used to calculate bandwidth sharing among remaining Classes of Service (within each trafc classication in-contract trafcis favored over out-of-contract trafc)***Where BW is the CIR for service and XXX is the unique code to differentiate proles within a QoS package.

This should provide best utilization of bandwidth with minimalto no impact to applications within the network. The primary function of QoS features is to differentiate trafc types competing for bandwidth in a network. Used properly this feature can help the customer forgo bandwidth upgrades while maintaining performance of mission-critical applications. However, QoS is not a substitute for sufcient bandwidth. Its features are intended to provide deterministic behavior during periods of network congestion. This behavior represents a trade off; usually favoring time sensitive mission critical applications over less time sensitive or less critical applications during congestion.White Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 12Frequently Asked Questions (FAQ)Section 1 MarketQWhere does FPL FiberNet offer Ethernet services?AFPL FiberNet offers Ethernet services at the following Metros in Florida; Miami, Fort Lauderdale, West Palm Beach, Orlando, Sarasota, Tampa, Jacksonville,Daytona, Naples, Fort Myers, Tallahassee and Atlanta.Section 2 Network Architecture QWhat network architecture does FPL FiberNet use to deliver Ethernet services?ABelow is a description of FPL FiberNets network for delivering Ethernet services:Core/EdgeMPLS NetworkAlcatel 7750/7450 Service PlatformInterconnected via 10G linksProtected for power, ber, route, and equipmentAggregation MPLS or Ethernet Switch NetworkAlcatel 7710/7210 Service PlatformInterconnected via 1G/10G links Access Ethernet Switch Network, EoDWDM, EoSONET, or EoTDM.Protection of ber & route available as value added featurePower provided by customerSection 3 Access QDoes FPL FiberNet support Ethernet, Fast Ethernet and Gigabit Ethernet?AFPL FiberNet supports Ethernet (10Mbps), Fast Ethernet/FE (100Mbps) and Gigabit Ethernet/GE (1000Mbps)Q Does FPL FiberNet support multiple physical interfaces for Ethernet, Fast Ethernet and Gigabit Ethernet?AFPL FiberNet supports all the following media, interfaces, connectors at all locationsPORT MEDIA PHYSICAL INTERFACECONNECTORDISTANCE10BaseTXCAT5e cableN/A100m100BaseTXCAT5e cableN/A100m100BaseFXsingle-mode berLC2km1000BaseTXCAT5e cableN/A100m1000BaseSXmulti-mode berLC500m1000BaseLXsingle-mode berLC2kmNote: Cross-connect distance limitations may prevent the use of certain interface types.White Paper:Ethernet VPN 2010 FPL FIberNet, LLCCondential and Propriety August, 2010 13QDoes FPL FiberNet offer fractional Ethernet services?
