1. 1 Carrier Ethernet Services Overview March 2007

2. 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. 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. 4 Carrier Ethernet Network UNI MEF Carrier Ethernet Terminology 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 CE: Customer Equipment, UNI: User Network Interface. MEF certified Carrier Ethernet products CE

5. 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. 6 Carrier Ethernet: Two Service Types Using EVCs 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. E-Line Service type E-LAN Service type Point-to-Point EVC Carrier Ethernet Network UNI: User Network Interface, CE: Customer Equipment CE UNI CE Multipoint-to-Multipoint EVC Carrier Ethernet Network CE UNI MEF certified Carrier Ethernet products CE UNI

7. 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 Carrier Ethernet Network UNI

8. 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 Point-to-Point EVC Carrier Ethernet Network CE UNI CE UNI CE UNI ISP POP UNI Storage Service Provider Internet

9. 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 Multipoint-to-Multipoint EVC Carrier Ethernet Network CE UNI CE UNI CE UNI

10. 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 Point-to-Multipoint EVC Carrier Ethernet Network CE UNI CE UNI CE

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

12. 12 TDM Circuits (e.g. T1/E1 Lines) 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) Circuit Emulated TDM Traffic

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

14. 14 Related MEF Services Specifications PurposeDefines the Ethernet Services (EPL, EVPL, E-Line, ELAN, etc) MEF 6 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.
