1 1 MEF Service Types and Service Definitions Overview and Use Cases Ralph Santitoro Presentation best viewed in slideshow mode

2 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Update from 1Q11 Quarterly Meeting in Miami Specification name change –OVC Services Definitions changed to: Ethernet Access Services Definitions Terminology Changes –E-Access Line Service Type changed to: E-Access Service Type Why? Enables single service type to cover current Point-to-Point and future Multipoint services –Service Definition Name Changes: E-APL renamed to Access EPL E-AVPL renamed to Access EVPL New Term Defined: Ethernet Access Provider

3 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC The Big Picture View for Site to Site Services Point-to-Point EVC Example UNIs at Subscriber Locations ENNI between: –Ethernet Access Provider (operator) and Retail Service Provider Point-to-Point (P2P) OVCs between: –OVC 1 between Subscriber UNI 1 and Ethernet Access Provider ENNI –OVC 2 Retail Service Provider ENNI and Subscriber UNI 2 P2P EVC between Subscriber UNIs E-NNI Ethernet Access Provider Retail Service Provider UNI 1 UNI 2 P2P OVC 1 P2P OVC 2 Subscriber ENNI P2P EVC

4 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Ethernet Service Definition Framework UNI-to-UNI (EVC-based) Service Types (MEF 6.1) –E-Line: Point-to-Point –E-LAN: Multipoint-to-Multipoint –E-Tree: Rooted Multipoint UNI(s) to ENNI (OVC-based) Service Type (New Spec.) –E-Access Point-to-Point services currently being defined Multipoint-to-Multipoint services may be defined –In future update to specification Ethernet Service Type Ethernet Service Type: Marketing term to categorize a service

5 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Ethernet Service Definition Framework Ethernet Service Attributes and Parameters (per Service Type) –Specifies requirements for: EVCs, UNIs, EVC per UNI OVC per UNI or ENNI endpoint Layer 2 Control Protocol (L2CP) disposition Ethernet Service Type Service Attributes Enable Service Differentiation

6 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Ethernet Service Classification and Definitions for EVC-based Services MEF EVC-based services are classified into 2 categories: –Port-based Single Service Instance (EVC) per UNI (dedicated UNI) –VLAN-aware Multiple Service Instances (EVCs) per UNI (multiplexed UNI) Ethernet Service Types are Umbrella categories

7 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Ethernet Service Classification and Definitions for Ethernet Access Services (UNI to ENNI) Ethernet Access Services classified into two categories (just like EVC-based services) : Port-based at the UNI endpoint Single OVC Instance per UNI (dedicated UNI endpoint) VLAN-aware at the UNI endpoint Multiple OVC Instances per UNI endpoint (multiplexed UNI endpoint) ENNI supports multiplexed Access EPLs or Access EVPLs Access EPL = Port-based P2P Ethernet access service Access EVPL = VLAN-aware P2P Ethernet access service Access EPL = Port-based P2P Ethernet access service Access EVPL = VLAN-aware P2P Ethernet access service

8 8 Frequently Asked Questions

9 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Ethernet Access Services FAQs Ethernet Access Services are point-to-point. Does this limit retail services to E-Line ? –No. Any E-Line (P2P) and E-LAN (MP2MP) services can be delivered using Ethernet Access Services. Access EPL is defined with a single CoS. Does this limit a retail service to a single CoS? –No. Retail provider can define a multi-CoS service. –Access EPL CoS must be selected to meet the multi-CoS requirements

10 10 Use cases and examples This section should be viewed in slide show mode

11 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Ethernet Private Line (EPL) example that uses Access EPL Retail Provider orders Access EPL from Ethernet Access Provider –Access provider constructs OVC 1 between Subscriber UNI 1 and ENNI Retail Service Provider constructs OVC –OVC 2 between ENNI and Subscriber UNI 2 Retail Provider constructs EVC between subscriber locations Retail Service Provider delivers EPL to Subscriber E-NNI Ethernet Access Provider Retail Service Provider UNI 1 UNI 2 P2P OVC 1 Subscriber ENNI P2P OVC 2 P2P EVC Access EPL ordered EPL delivered

12 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Internet Access Service example using Access EPL ISP orders Access EPL from Ethernet Access Provider –Access provider constructs OVC between Subscriber UNI and ENNI ISP delivers Internet Access Service E-NNI Ethernet Access Provider Internet Service Provider UNI P2P OVC Subscriber ENNI Access EPL ordered

13 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC EVPL Example using Access EPL Retail Provider orders Access EPL from Ethernet Access Provider –Access Provider constructs OVC between Subscriber UNI 1 and ENNI Retail Service Provider constructs OVC 2 between: –ENNI and Subscriber UNI 2 Retail Provider constructs P2P EVC between subscriber sites 1 & 2 –Retail Provider delivers EVPL 1 to Subscriber Subscriber adds new site and wants to connect to site 2 Retail Provider constructs P2P EVC between subscriber sites 2 & 3 –Retail Service Provider delivers EVPL 2 to Subscriber E-NNI Ethernet Access Provider Retail Service Provider UNI 1 UNI 2 P2P OVC 1 Subscriber Site 2 Subscriber Site 1 ENNI P2P OVC 2 P2P EVC Access EPL ordered EVPL 1 delivered P2P EVC EVPL 2 delivered Subscriber Site 3

14 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC EVPL Example using Two Access EPLs Retail Provider buys Access EPL 1 from Ethernet Access Provider –To connect Subscriber Site 1 UNI 1 to ENNI Retail Provider buys Access EPL 2 from Ethernet Access Provider –To connect Subscriber Site 2 UNI 2 to ENNI Retail Service Provider sells EVPL 1 to Subscriber –To connect Subscriber Sites 1 and 2 Retail Service Provider sells EVPL 2 to Subscriber –To connect Subscriber Sites 2 and 3 E-NNI Ethernet Access Provider Retail Service Provider UNI 1 UNI 2 UNI 3 Subscriber Site 2 Subscriber Site 1 ENNI Access EPL 1 Access EPL 2 EVPL 2 Subscriber Site 3 EVPL 1

15 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC EP-LAN Service example using 2 Access EPL tail circuits Retail Provider buys Access EPL 1 Ethernet Access Provider 1 –To connect Subscriber Site 1 UNI 1 to ENNI 1 Retail Provider buys Access EPL 2 from Ethernet Access Provider 2 –To connect Subscriber Site 2 UNI 2 to ENNI 2 Retail Service Provider sells EP-LAN to Subscriber –To connect Subscriber Sites 1, 2 and 3 Ethernet Access Provider 1 Retail Service Provider UNI 1 UNI 2 Subscriber Site 2 Subscriber Site 1 E-NNI 1 Access EPL 1 Subscriber Site 3 Two off-net sites reached using Access EPLs Ethernet Access Provider 2 E-NNI 2 UNI 3 Access EPL 2 EP-LAN

16 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC EVPL Example using 1 Access EPL and 2 Access EVPLs Retail Provider buys Access EPL from Ethernet Access Provider 1 –To connect Subscriber Site 1 UNI 1 to ENNI 1 Retail Provider buys Access EVPL 1 from Ethernet Access Provider 2 –To connect Subscriber Site 2 UNI 2 to ENNI 2 Retail Service Provider delivers EVPL 1 to Subscriber –To connect Subscriber Sites 1 UNI 1 and 2 UNI 2 Retail Provider buys Access EVPL 2 from Ethernet Access Provider 2 –To connect Subscriber Site 2 UNI 2 to ENNI 2 –2 OVCs multiplexed at UNI 2 Retail Service Provider delivers EVPL 2 to Subscriber –To connect Subscriber Site 2 UNI 2 and Site 3 UNI 3 Ethernet Access Provider 1 Retail Service Provider UNI 1 UNI 2 Subscriber Site 2 Subscriber Site 1 ENNI 1 Access EPL Subscriber Site 3 Ethernet Access Provider 2 ENNI 2 UNI 3 EVPL 1 Access EVPL 1 Access EVPL 2 EVPL 2

17 Q2 QUARTERLY MEETING – PRAGUE, CZECH REPUBLIC Summary EVCs can be composed of 2 or more OVCs –If there is no ENNI, there are no OVCs New E-Access Ethernet Service Type –Category of services which provide connectivity between one or more UNIs and one ENNI –Targeting Wholesale Ethernet Access Services Access EPL (Access Ethernet Private Line) –Port-based P2P Ethernet Access Service Definition Supporting 1 access service per UNI –Consists of 1 UNI and 1 ENNI Access EVPL (Access Ethernet Virtual Private Line) –VLAN-aware P2P Ethernet Access Service Definition Supports multiple access services per UNI –Consists of 1 UNI and 1 ENNI
