Ethernet as an Interface
A universal “jack” To the network Within the network
Easy to increase bandwidth without changing the port itself
Single “jack” can support multiple services on the same port
Well understood by enterprises and equipment vendors
Monster volumes - low cost

Ethernet Services Utilization
ATM, FR, Private Line are large and slowly growing
Ethernet services are < 5% of ATM, FR, and PL revenue
Important market inhibitors have been Lack of QoS capabilities Uniform and powerful
management and operations Ubiquity of service offerings Cross-elasticity with high margin

Co-existed with and relied upon traditional transport networks Many Ethernet services
deliberately utilize traditional transport
SONET MSPP still the top choice for Ethernet transport Highly deployed and

Ethernet Service Drivers - Customers
Price per Megabit Higher bandwidth for less cost using less expensive interfaces Converged “best-effort” and high-priority services in single connection
Dial-able Bandwidth Customer purchases “100 Mbps” facility, pays for 10 Mbps service Service provider scales bandwidth in-service to 20, 30, 50, etc. Mbps
Perceived Value of VoIP Voice seen as “add-on” service to Ethernet
Customer Needs Are Expanding HIPPA, Sarbanes-Oxley Disaster Recovery/Business Continuity (DR/BC) E-commerce expansion
Heightened Network Survivability Requirements Service guarantees
Looking To MEF for Certified Carrier Solutions

Ethernet Service Drivers - Carriers
Competitive Environment CLEC and start-up firms gaining traction with Ethernet-only services Offensive (revenue increase) and defensive (protect customer base) play
Carriers Outgrowing Frame Relay Networks Ethernet currently more costly than Frame Relay Differentiated service offerings covers difference
Standardized Delivery Solutions VLAN stacking, EoS, GFP, VCAT, LCAS, MPLS, RPR, link aggregation, services inter-
working Combinations of TDM and Ethernet services Ethernet-over-Copper (EoCu) Reduced complexity for adding new services or customers to network
Ubiquity of Service Offerings Further Fuels Demand MEF Services Certification fuels consistency
Triple-Play Offering Disruption Residential broadband overwhelms business customer traffic Migration to IPDSLAM

A Word About QoS…
QoS attributes for all MEF service typesFrame delayFrame delay variationFrame loss
Typical switching gear provides “Soft QoS” or Statistical QoSHandled on a hop-by-hop basis Ethernet uses P-bits in the VLAN tag header (4096 tags)
‘Priority’ marking: 3 bits – 8 levelsWorks well for aggregation but limited for core applications
IP uses Diff Serv Code Points (DSCP) in the IP header‘Priority’ marking: 6-bits – 64 levels
These techniques work “on average” Connection-oriented protocols use more than priority
MPLS/ATM/FR - QoS is associated with the connection
December 2005Copyright 2005 Fujitsu Network Communications17
A Word About Pseudowires
A pseudowire encapsulates protocols into a connection-oriented container Easily multiplexed and transported Correlation: Digital wrapper, IP Tunnel
A pseudowire can also be thought of as a kind SONET VT1.5 Bandwidth can be flexibly provisioned (or signaled) QoS can be guaranteed
A pseudowire uses the MPLS frame format Placed into an MPLS tunnel for easy transport across an MPLS backbone

MEF Service Concept
UNI: Standard Ethernet interface that is the point of demarcation between the customer equipment and the service provider’s MEN
EVC: An instance of association of two or more UNIs that helps conceptualize the service connectivity – frames can only be exchanged among the associated UNIs
