9 Carrier Ethernet Is Great!

… But What Do We Mean By “Ethernet”?

10 “Ethernet” – Different Points of View

• Ethernet as a point-to-point link IEEE 802.3 view • Ethernet as a packet switched network (PSN) infrastructure IEEE 802.1 (bridging) view ITU-T SG15 / SG13 managed Ethernet network view • Ethernet as a service MEF view – user-to-user transfer of 802.3 frames over any transport layer Think E-Line, E-LAN and (soon) E-Tree

11 Carrier Ethernet – Service Provider View

• A set of interconnected network elements transporting Carrier Ethernet services for all users, locally & worldwide • Carrier Ethernet services are carried over physical Ethernet networks and other legacy transport technologies

12 Carrier Ethernet – User View

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

13 The End Goal is Carrier Ethernet

Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet

Attribute 1: Standardized Services

14 Standards Enable Standardized Services

Point-to-point EVC, E-Line Point-to-Point EVC Like Duplex Ethernet CE CECE CE UNI UNI UNIUNI

Multipoint EVC, CECE Multipoint EVC Like VLAN, E-LAN UNIUNI CECE Multi-Site UNIUNI Any-to-any

Point-to-multipoint, Like EPON Ethernet, CECE E-TREE UNIUNI Root-to-Leaf and Rooted Multipoint Rooted Multipoint EVC Leaf-to-Root (proposed) CECE UNIUNI

15 The End Goal is Carrier Ethernet

Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet

Attribute 2: Scalability

16 Standards Enable Scalability

Carrier Ethernet supports identical services over many physical media • Enterprise customers: Flexible business services • Residential customers – Scalable Triple Play Services • Mobile Carriers – Broadband data services (3G/4G/WiMax) Easily upgradeable; backwards compatible Several transport technologies add the notion of hierarchy to a Carrier Ethernet network (like MPLS, PBB/PBB-TE, MPLS-TP) – enable large numbers of customers in a Carrier Ethernet network

17 Ethernet Fiber Access Link Options

Maximum Symmetric Bandwidth Future

100Base-L/BX10 1000 (Single Mode Fiber) Base- 10Mbps PX20 Ethernet over Copper PON

750m 2000m 5000m 10km 20km Minimum Reach

• Fiber-based Ethernet access offers more bandwidth/distance flexibility • Multiple options for Ethernet in the First Mile and GE-PON available • Æ Requires an upgrade to metro and core networks

18 The End Goal is Carrier Ethernet

Carrier Ethernet is a ubiquitous, standardized, carrier-class SERVICE defined by five attributes that distinguish Carrier Ethernet from familiar LAN based Ethernet

Attribute 3: Service Management

19 Influence of OAM On Infrastructure Cost

• Ethernet vendors often advertise low investment (Capex) costs • What about operational cost (Opex)? – Largest fraction of opex cost: Provisioning and troubleshooting – Carriers cannot afford to field service the FTTx components in the edge • Ethernet OAM (IEEE 802.1ag) eliminates field service needs • Can be deployed across different types of technologies used for Metro Ethernet Networks • Also assists in fast fault detection and isolation (leads to reliability)

E-NNI

Provider 1 Provider 2

• Nobody has footprint everywhere. The interconnection of Carrier Ethernet networks is one of the last hurdles for ubiquitous Ethernet services • Need a common language for peering • E-NNI is a reference point representing the boundary between two Carrier Ethernet Networks, each in a different administrative domain • Draft # 4 is the latest version; many comments pending
