Carrier Ethernet Defined
Carrier Ethernet for the Business Users:
• The 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.
Carrier Ethernet for Service Providers:
• A set of certified network elements that connect to transport
Carrier Ethernet services for all users, locally & worldwide.
• Carrier Ethernet services are carried over physical Ethernet
networks and other legacy transport technologies.

What is Carrier Ethernet?
•
Question:
–
•
Answer for an end-user
–
•
“Is it a service, a network, or a technology?”
It’s a Service defined by 5 attributes
Answer for a service provider
–
–
–
It’s a set of certified network elements that connect
to transport the services offered to the customer
It’s a platform for value added services
A standardized service for all users

Premium Carrier
Ethernet Demarcation
Equipment is required
Forces operators to look for
new revenues based on
dynamic QoS and SLA

Traffic Management
TM Tools
• CoS classification
• Policing
• P-bit remarking
• Hierarchical Scheduling
• Per EVC Shaping
•
•
•
•
Enables oversubscription by managing priority and congestion
Provides tools to fix congestion issues reported by OAM
Benefit: Enables end-to-end SLA’s over any network
Benefit: Offer premium services at premium prices

Example:
Dynamic Traffic Management
“Fast lane” Solution:
• Move from Best effort service to a tiered CoS
• Tariff is dynamic (higher during peak hours to throttle
traffic and guarantee SLA for those drivers willing to pay)
Best Effort Service
isn’t always Pretty

Traffic Management at Customer Demarc
Adds tools to Optimize and Accelerate Traffic Performance
Traffic Management Tools conform traffic to BW profiles and
ensure End-to-End SLA on a per service basis:
• Ensures higher priority traffic is served first and not dropped

Connecting Communities QoS and SLA for Rural Broadband
Broadband connection to remote communities
• 20% Caribbean Population is considered
Rural (out of reach).
• Unlicensed Wireless Connections is a effective
solution that can provide High capacity Ethernet
per sector

Essential Components for Carrier Ethernet
For Accelerated Service Delivery and Maximized Profitability
Service Validation and Assurance • Circuit Validation (RFC-2544, Y.1564, MAC/IP Swap loopbacks)
OPEX Reducing Tools
• Circuit Validation
• Fault detection
• Fault Analysis
• Fault correction
•
•
•
•
OAM helps detect and isolate faults and take corrective action
Benefit: Proactive testing improves response times
Benefit: Hardware OAM tools reduces OPEX (less truck rolls)
Benefit: Fault propagation, EVC redundancy, ring redundancy,..
