 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

choice for Ethernet transport
 Highly deployed and
understood
 Ethernet capable
Equipment used for
Ethernet services by %
 Co-existed with and relied
upon traditional transport
networks
 Technologies overlap

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 interworking
 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 types
 Frame delay
 Frame delay variation
 Frame loss
 Typical switching gear provides “Soft QoS” or Statistical QoS
 Handled on a hop-by-hop basis
 Ethernet uses P-bits in the VLAN tag header (4096 tags)
 ‘Priority’ marking: 3 bits – 8 levels
 Works 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
16

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
