5
Five Attributes of Carrier Ethernet
Services – must support Translation of MEF EVPL, E-Line,
E-LAN service types and profiles with multiple CoS
Quality of Service – Service Monitoring
Must support enforceable, measurable, end-to-end service
(frame delay, delay variation, availability).
Service Management – Process Integration
Must support normalized process human and system for
process transactions
Reliability – Protection. Must provide protection: carrier
class with geographical diversity
Scalability – Scalability. Must support and access millions
of EVCs and worldwide locations with scalable processes
6
Carrier Ethernet Terminology
•
UNI (User-to-Network Interface)
– Physical interface/demarcation between service provider and subscriber
– Service start/end point
•
Ethernet Virtual Connection (EVC)
– An association of two or more UNIs
•
Three types of EVC
– Point-to-Point
– Multipoint-to-Multipoint
– Rooted Multipoint (Point-to-Multipoint)
•
EVCs and Services
In a Carrier Ethernet network, data is transported across Point-to-Point, Point-toMultipoint and Multipoint-to-Multipoint EVCs according to the attributes and definitions
of the E-Line and E-LAN services
•
NNI (Network-to-Network Interface)
– Demarcation/peering point
• Between service providers (NNI)
• Between service provider internal networks (I-NNI)

Bandwidth Profiles & Traffic Management
Bandwidth Profiles per EVC (service) and per CoS
– CIR (Committed Information Rate)
• CIR assured via Bandwidth Reservation and Traffic
Engineering
– EIR (Excess Information Rate)
• EIR bandwidth is considered ‘excess’
• Traffic dropped at congestion points in the network
– CBS/EBS (Committed/Excess Burst Size)
• Higher burst size results in improved performance

BWPs can divide bandwidth per EVC
(service) over a single UNI
– Multiple services over same port (UNI)
– CoS markings enable the network to
determine the network QoS to provide
CIR defines the assured bandwidth EIR
improves the network’s Goodput

Carrier Ethernet Interconnect Challenge
Operators need to interconnect
their Carrier Ethernet Networks
• Current implementations
UNI B2
UNI A1
UNI A2
– Limited in features,
proprietary and/or ad-hoc
– Differing feature and
functionality transparency
– Do not support MEF Carrier
Ethernet services
– Require extensive discussions
between operators in order to
verify each operator’s Carrier
Ethernet product and
operational capabilities

Carrier Ethernet Interconnect Brings Global Reach
Interconnects facilitate service delivery that span multiple
operators networks
•
•
•
Standard Carrier Ethernet service handoffs between operators simplifies provisioning and
troubleshooting across multiple networks
Reduces time to revenue by cutting lead time to deliver the service
Lowers cost to manage the service once its turned up

Carrier Ethernet Exchange Model
• Implements MEF ENNI to enable Carrier Ethernet
interconnection at strategic points
• Enables multiple virtual connections over a single physical
connection
• Exchange presents an MEF ENNI interface to connected
service providers and acts as an MEF Operator Virtual
Connection (OVC)
• Simplifies and lowers
implementation, costs
and creates scalability
up and down
• Enables much larger
market for Ethernet
