  1. Carrier Ethernet Services Overview March 2007

  2. Agenda • Carrier Ethernet Terminology • The UNI • Ethernet Virtual Connections (EVCs) • E-Line Services • Ethernet Private Line • Ethernet Virtual Private Line • E-LAN Services • Multipoint Services • EVCs and Services • Circuit Emulation Services • Carrier Ethernet Architecture for Cable • Carrier Ethernet in Access Networks • MEF Specifications March 2007

  3. Purpose • Carrier Ethernet Services Overview • This presentation defines the MEF Ethernet Services that represent the principal attribute of a Carrier Ethernet Network • This presentation is intended to give a simple overview as a grounding for all other MEF documents

  4. The User Network Interface (UNI) The UNI is the physical interface or port that is the demarcation between the customer and the service provider/Cable Operator/Carrier/MSO The UNI is always provided by the Service Provider The UNI in a Carrier Ethernet Network is a physical Ethernet Interface at operating speeds 10Mbs, 100Mbps, 1Gbps or 10Gbps MEF Carrier Ethernet Terminology Carrier Ethernet Network UNI CE CE: Customer Equipment, UNI: User Network Interface. MEF certified Carrier Ethernet products

  5. MEF Carrier Ethernet Terminology • Ethernet Virtual Connection (EVC) • Connects two or more subscriber sites (UNI’s) • An association of two or more UNIs • Prevents data transfer between sites that are not part of the same EVC • Three types of EVC • Point-to-Point • Multipoint-to-Multipoint

  6. E-Line Service used to create Ethernet Private Lines Virtual Private Lines Ethernet Internet Access E-LAN Service used to create Multipoint L2 VPNs Transparent LAN Service Foundation for IPTV and Multicast networks etc. Carrier Ethernet: Two Service Types Using EVCs E-Line Service type Point-to-Point EVC UNI UNI CE CE Carrier Ethernet Network E-LAN Service type CE UNI Carrier Ethernet Network UNI Multipoint-to-Multipoint EVC CE MEF certified Carrier Ethernet products UNI: User Network Interface, CE: Customer Equipment

  7. EVCs and Services In a Carrier Ethernet network, data is transported across Point-to-Point and Multipoint-to-Multipoint EVCs according to the attributes and definitions of the E-Line and E-LAN services Point-to-Point EVC UNI UNI Carrier Ethernet Network

  8. Services Using E-Line Service Type • Ethernet Private Line (EPL) • Replaces a TDM Private line • Dedicated UNIs for Point-to-Point connections • Single Ethernet Virtual Connection (EVC) per UNI Storage Service Provider UNI CE UNI Carrier Ethernet Network ISP POP Internet CE UNI UNI Point-to-Point EVC CE

  9. Services Using E-Line Service Type • Ethernet Virtual Private Line (EVPL) • Replaces Frame Relay or ATM services • Supports Service Multiplexed UNI (i.e. multiple EVCs per UNI) • Allows single physical connection (UNI) to customer premise equipment for multiple virtual connections Service Multiplexed Ethernet UNI CE UNI Carrier Ethernet Network CE UNI UNI CE Multipoint-to-Multipoint EVC

  10. Services Using E-LAN Service Type • Ethernet Private LAN and Ethernet Virtual Private LAN Services • Supports dedicated or service-multiplexed UNIs • Supports transparent LAN services and multipoint VPNs Service Multiplexed Ethernet UNI UNI UNI CE Carrier Ethernet Network UNI CE UNI CE Point-to-Multipoint EVC

  11. Carrier Ethernet in Access Networks Wireless Backhaul Bringing vastly extended scalability for business and residential users HD TV TVoD, VoD Gaming, Business Backup, ERP Voice/Video Telephony Voice gateway Video Source Video Source Global/National Carrier Ethernet COPPER, FIBER, COAX and WIRELESS Business Broadband Metro Carrier Ethernet Broadband mobile data/video Carrier Ethernet Access E-Line and E-LAN service Residential Triple-Play Small/Medium Business FTTx and DSLAM , Cable Modem

  12. Circuit Emulation Services over Carrier Ethernet • Enables TDM Services to be transported across Carrier Ethernet network, re-creating the TDM circuit at the far end • Runs on a standard Ethernet Line Service (E-Line) Carrier Ethernet Network TDM Circuits (e.g. T1/E1 Lines) TDM Circuits (e.g. T1/E1 Lines) Circuit Emulated TDM Traffic

  13. Carrier Ethernet Architecture for Cable Operators Local Broadcaster Local Venues Head End Hub Commercial Business Services over Fiber E-Line High Speed Internet E-LAN SDB/SO CTL D2A ATV EQAM Off Air Video Server E-Line & E-LAN CMTS A2D Ad Insertion SMB served over Cable STB Ctrl VOD CTL HD TV TVoD, VoD 10GbE Optical Metro Ring Network Hub Video Source Gaming, Business Backup, ERP Voice/Video Telephony Hub Voice gateway • Dedicated Fiber end-points • DOCSIS end-points • MEF E-Line • EPL (Ethernet Private Line) • EVPL (Ethernet Virtual Private Line) • MEF E-LAN • Converged Services (Video, VoIP, HSI, VPNs) MEF 9 and MEF 14 certified Carrier Ethernet products

  14. Related MEF Services Specifications MEF 6 Metro Ethernet Services Definitions Phase I Purpose Defines the Ethernet Services (EPL, EVPL, E-Line, ELAN, etc) Ethernet Services Attributes Phase 2 MEF 10.1 Purpose Defines the service attributes and parameters required to offer the services defined in MEF 6. Updated from Original MEF 10 in October 2006 Audience Appropriate for equipment vendors, service providers, and business customers, since it provides the fundamentals required to build devices and services that deliver Carrier Ethernet. For Enterprise users it gives the background to Service Level Specifications for Carrier Ethernet Services being offered by their Service Providers and helps to plan Ethernet Services as part of their overall network.
