The need and demand for a simple ubiquitous service 2. Requirement to scale network services to enable rapid deployment of applications critical to enterprises and service providers. 3. Availability of low cost, high bandwidth of Ethernet, beyond the LAN 4. Convergence of business, residential and wireless services Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 3 Carrier Ethernet Scope and Expansion Bringing vastly extended scalability for business and residential users HD TV TVoD, VoD Gaming, Business Backup, ERP Voice/Video Voice Telephony gateway Wireless Backhaul Video Source Video Source Business Broadband Carrier Ethernet Network E-Line and E-LAN service Broadband mobile data/video Residential Triple-Play Small/Medium Business FTTx and DSLAM , Cable Modem 4 MEF Carrier Ethernet Terminology • Ethernet Virtual Circuit (EVC) – An association of two or more UNIs – UNI is a Ethernet interface. – Connects two or more subscriber sites (UNI’s) – Prevents data transfer between sites that are not part of the same EVC. – Three types of EVC • Point-to-Point • Point-to-Multipoint • Multipoint-to-Multipoint 5 MEF Specifications Overview MEF 6 Purpose Metro Ethernet Services Definitions Phase I Defines the Ethernet Services (EPL, EVPL, E-Line, ELAN, etc) All, 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. Technical Committee Service Area Audience MEF 10.1 Purpose Ethernet Services Attributes Phase 2 Defines the service attributes and parameters required to offer the services defined in MEF 6. Updated from Original MEF 10 All, 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 Standardized Services as part of their Services network. overall Technical Committee Service Area Contents Carrier Ethernet Technical Future Work Marketing Certification Membership Audience 6 Carrier Ethernet: Two Service

is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet • It brings the compelling business benefit of the Ethernet cost model to achieve significant savings • Standardized Services Carrier Ethernet Attributes • Scalability • Service Management • Reliability • Quality of Service Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 11 The 5 Attributes Carrier Ethernet (1) Attribute 1: Standardized Services • E-Line, E-LAN provide transparent, private line, virtual private line and multi-point to multi-point LAN services. • A ubiquitous service provided globally & locally via standardized equipment • Requires no changes to customer LAN equipment or networks and accommodates existing network connectivity such as, time-sensitive, TDM traffic and signaling • Ideally suited to converged voice, video & data networks • Wide choice and granularity of bandwidth and quality of service options Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 12 The 5 Attributes Carrier Ethernet (2) Attribute 2: Scalability • The ability for millions to use a network service that is ideal for the widest variety of business, information, communications and entertainment applications with voice, video and data • Spans Access & Metro to National & Global Services over a wide variety of physical infrastructures implemented by a wide range of Service Providers • Scalability of bandwidth from 1Mbps to 10Gbps and beyond, in granular increments Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 13 The 5 Attributes Carrier Ethernet (3) Attribute 3: Reliability • The ability for the network to detect & recover from incidents without impacting users • Meeting the most demanding quality and availability requirements • Rapid recovery time when problems do occur, as low as 50ms Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 14 The 5 Attributes Carrier Ethernet (4) Attribute 4: Quality of Service • Wide choice and granularity of bandwidth and quality of service options • Service Level Agreements (SLAs) that deliver end-to-end performance matching the requirements for voice, video and data over converged business and residential networks • Provisioning via SLAs that provide end-to-end performance based on CIR, frame loss, delay and delay variation characteristics Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 15 The 5 Attributes Carrier Ethernet (5) Attribute 5: Service Management • The ability to monitor, diagnose and centrally manage the network, using standards-based vendor independent implementations • Carrier-class OAM • Rapid service provisioning Contents Carrier Ethernet Technical Future Work Marketing Certification Membership 16 Drivers for Carrier Ethernet in the Cable Industry • Standardization – Definition of Carrier Ethernet & implementation of products to MEF specifications creates standardized networking within and between MSOs • Certification now available for
