Stakeholders of Carrier Ethernet

• Service Providers
• Carrier Ethernet in the Metro Network
• Reduce Complexity of Network - Converged services
  
• Reducing CAPEX and OPEX
• Ethernet is less complex / expensive than legacy
  ATM/SONET/TDM
• Use Ethernet as a backhaul technology for access
  technologies
• Enables new revenue streams by providing new
  services
• Customers are demanding bandwidth - Ethernet
  services!

• Enterprises/SMBs
• Converged network services for business
  applications
• Data, VoIP, Video, conf, offsite-storage

• Reduced technical complexity
• Reduced telecomm/IT costs
• Standardize on Ethernet
• Reduces Network management complexity
• Reduces requirements of telecomm/IT expertise /
  support cost
• Bandwidth transport (up to 10Gbps)
• High speed, low latency flexible service
• Easy incremental / scalability / upgrades of
  services

The 5 Attributes of the Carrier Ethernet
13
The Five Attributes of Carrier Ethernet

• Carrier Ethernet is a ubiquitous, standardized,
  carrier-class SERVICE defined by five
  attributes that distinguish Carrier Ethernet
  from familiar LAN based Ethernet
• It brings the compelling business benefit of the
  Ethernet cost model to achieve significant
  savings

Carrier Ethernet
Carrier Ethernet Attributes

• Standardized Services

• Scalability

• Reliability

• Quality of Service

• Service Management

14
The 5 Attributes Carrier Ethernet (1)
Attribute 1 Standardized Services

• Ubiquitous services provided locally globally
  via providers.
• E-Line, E-LAN, E-Tree provide transparent,
  private line, virtual private line and
  multi-point to multi-point LAN services.
• Using standardized equipment.
• Accommodates existing customer LAN equipment.
• Accommodates existing transport infrastructure
  technology including TDM.
• Enables converged voice, video data networks.

15
The 5 Attributes Carrier Ethernet (2)
Attribute 2 Scalability

• Enables different levels and variety of business,
  information, communications and entertainment

  availability requirements.
• Rapid recovery time when problems do occur as
  low as 50ms.

17
The 5 Attributes Carrier Ethernet (4)
Attribute 4 Quality of Service

  end-to-end performance matching the requirements
  for voice, video and data over converged business
  and residential networks.
• Provisioning via SLAs that provide end-to-end
  performance based on committed information rate
  (CIR), frame loss, delay and delay variation
  characteristics.

18
The 5 Attributes Carrier Ethernet (5)
Attribute 5 Service Management

• The ability to monitor, diagnose and centrally
  manage the network, using standards-based vendor
  independent implementations.
• Carrier-Class OAM.
• Rapid service provisioning.

19
MEF Documents and Certification
20
Technical Document Types

• Technical Specification
• Document detailing the agreed upon definitions,
  scope, methods and procedures for a component of
  Carrier Ethernet
• Implementation Agreement
• A document describing an agreement as to how
  options in existing technical specifications or
  other standards bodies work shall be implemented
• Test Specification
• A document describing how attributes of Carrier
  Ethernet technical specifications will be tested
  for compliance against those specifications
• Also called Abstract Test Suite
• Position Statement
• An Outgoing Liaison with other standards
  organizations describing the MEF

• Summary
• MEF is First Mile technology neutral
• Each First-Mile access method has strengths and
  weaknesses
• Service Providers choice should be based on its
  specific market requirements and economics
• End users choice should be based on its specific
  needs
• QA
