No user of this document is authorized to modify any of the information contained herein.

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 Topics What is Carrier Ethernet? –Architecture –Carrier Ethernet Terminology –The UNI, NNI, MEN, Ethernet Virtual Connections (EVCs) EVCs and Services E-Line Services –Ethernet Private Line, Ethernet Virtual Private Line E-LAN Services –Multipoint Services E-Tree Services Service Attributes –Service Parameters, Bandwidth Profiles, Traffic Management Circuit Emulation Services Carrier Ethernet Architecture for Cable Carrier Ethernet Class of Service Service Examples March 2007

5 5 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 A ubiquitous, standardized, carrier-class Service and Network defined by five attributes that distinguish it from familiar LAN based Ethernet

6 6 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

7 7 Carrier Ethernet Architecture EVC:Ethernet Virtual Connection UNI:User Network Interface. the physical demarcation point between the responsibility of the Service Provider and the responsibility of the Subscriber UNI-C:UNI customer-side processes UNI-NUNI network-side processes ENNI:External Network to Network Interface; the physical demarcation point between the responsibility of the two Service Providers ENNI-N:ENNI Processes Ethernet Services (Eth) Layer Terminology Service Provider 1 Carrier Ethernet Network CE UNI End User Subscriber Site ETHUNI-CETHUNI-NETHUNI-N ETHENNI-N ETHUNI-C UNI CE ENNI Service Provider 2 ETHENNI-N End User Subscriber Site EVC Carrier Ethernet Network In a Carrier Ethernet network, data is transported across Point-to-Point and Multipoint-to-Multipoint Ethernet Virtual Connections (EVCs) according to the attributes and definitions of the E-Line, E-LAN and E-Tree services

8 8 Carrier Ethernet Architecture Data Plane Control Plane Management Plane Transport Services Layer (e.g., IEEE 802.1, SONET/SDH, MPLS) Ethernet Services Layer (Ethernet Service PDU) Application Services Layer (e.g., IP, MPLS, PDH, etc.) APP Layer ETH Layer TRAN Layer Data moves from UNI to UNI across "the network" with a layered architecture. When traffic moves between ETH domains is does so at the TRAN layer. This allows Carrier Ethernet traffic to be agnostic to the networks that it traverses.

9 9 MEF Carrier Ethernet Terminology The User Network Interface (UNI) –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 Ethernet Virtual Connection (EVC) –Service container –Connects two or more subscriber sites (UNIs) –An association of two or more UNIs –Prevents data transfer between sites that are not part of the same EVC –Three types of EVCs Point-to-Point Multipoint-to-Multipoint Rooted Multipoint –Can be bundled or multiplexed on the same UNI –Defined in MEF 10.2 technical specification

10 10 Carrier Ethernet Terminology UNI Type I –A UNI compliant with MEF 13 –Manually Configurable UNI Type II –Supports E-Tree –Support service OAM, link protection –Automatically Configurable via E-LMI –Manageable via OAM Network to Network Interface (NNI) –Network to Network Interface between distinct MEN operated by one or more carriers –An active project of the MEF Metro Ethernet Network (MEN) –An Ethernet transport network connecting user end-points (Expanded to Access and Global networks in addition to the original Metro Network meaning)

DSCP: 6-bit Differentiated Services Code Point in IP frames

27 27 Mapping the CoS Model at an ENNI * Each CoS Label associated with particular CPO CoS Rock CoS Paper CoS Scissors CoS Plus CoS Square CoS Heart CoS Coal CoS Mapping? CoS Rock CoS Paper CoS Scissors CoS Plus CoS Square CoS Heart CoS Coal CoS Medium* CoS High* CoS Low* Without MEF CoS IA: MENs requires bilateral agreements at each ENNI. Customers may not get consistent QoS treatment With MEF CoS IA: MENs remark frames on egress of an ENNI to align based on standardized MEF CoS indications. Service Provider 1 Carrier Ethernet Network CE UNI CE ENNI Service Provider 2 Carrier Ethernet Network Common CoS lexicon between the Service Providers on either side of the standardized Ethernet interconnect facilitates CoS alignment: Providers are still free to implement a subset or superset of MEF CoS definitions MEF 23 specifies interoperability between CE Networks using up to 3 MEF CoS
