Soapstone Networks PNC

• Provider Network Controller (PNC) provides
  quality and capacity management for transport
  resources
• The tight coupling of fulfillment and assurance
  results in a true control plane
• Create and maintain resources through active
  monitoring of network elements
• Uniform reporting of performance, utilization,
  faults, and resource inventory
• Supports provisioning, fault correlation,
  performance and monitoring, capacity planning,
  and optimization as part of an overall integrated
  management system

Carrier Ethernet Defined
Carrier Ethernet is
A ubiquitous, standardized, carrier-class
Service and Network
Defined by five attributes that distinguish it
from familiar LAN based Ethernet  
5
The 5 Attributes Carrier Ethernet (1)
Attribute 1 Standardized Services

• E-Line, E-LAN provide transparent, private line,
  virtual private line and multi-point to
  multi-point LAN services.
• A ubiquitous service providing globally locally
  via standardized equipment
• Requires no changes to customer LAN equipment or
  networks and accommodates existing network
  connectivity such as, time-sensitive, TDM traffic
  and signaling
• Ideally suited to converged voice, video data
  networks
• Wide choice and granularity of bandwidth and
  quality of service options

6
The 5 Attributes Carrier Ethernet (2)
Attribute 2 Scalability

• The ability for millions to use a network service
  that is ideal for the widest variety of business,
  information, communications and entertainment
  applications with voice, video and data
• Spans Access Metro to National Global
  Services over a wide variety of physical
  infrastructures implemented by a wide range of
  Service Providers
• Scalability of bandwidth from 1Mbps to 10Gbps
  and beyond, in granular increments

7
The 5 Attributes Carrier Ethernet (3)
Attribute 3 Reliability

• The ability for the network to detect recover
  from incidents without impacting users
• Meeting the most demanding quality and
  availability requirements
• Rapid recovery time when problems do occur, as
  low as 50ms

8
The 5 Attributes Carrier Ethernet (4)
Attribute 4 Quality of Service

• Wide choice and granularity of bandwidth and
  quality of service options
• Service Level Agreements (SLAs) that deliver
  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 CIR, frame loss, delay and
  delay variation characteristics

9
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

10
MEF Carrier Ethernet Terminology

• The User Network Interface (UNI)
• The UNI is the physical interface or port that
  is the demarcation between the customer and the
  service provider/Cable Operator/Carrier/MSO
• The UNI is always provided by the Service
  Provider
• The UNI in a Carrier Ethernet Network is a
  physical Ethernet Interface at operating speeds
  10Mbs, 100Mbps, 1Gbps or 10Gbps

MEF Carrier Ethernet Terminology

• Ethernet Virtual Connection (EVC)
• Connects two or more subscriber sites (UNIs)
• An association of two or more UNIs
• Prevents data transfer between sites that are not
  part of the same EVC
• Three types of EVC
• Point-to-Point
• Multipoint-to-Multipoint
• Rooted-Multipoint (Point-to-Multipoint)

12
Carrier Ethernet Service Types Using EVCs
E-Line Service type

• E-Line Service used to create
• Ethernet Private Lines
• Virtual Private Lines
• Ethernet Internet Access
• E-LAN Service used to create
• Multipoint L2 VPNs
• Transparent LAN Service.

EVCs and Services

• In a Carrier Ethernet network, data is
  transported across Point-to-Point,
  Point-to-Multipoint and Multipoint-to-Multipoint
  EVCs according to the attributes and definitions
  of the E-Line and E-LAN services

Services Using E-Line Service Type

• Ethernet Private Line (EPL)
• Replaces a TDM Private line
• Dedicated UNIs for Point-to-Point connections
• Single Ethernet Virtual Connection (EVC) per UNI

Services Using E-Line Service Type

• Ethernet Virtual Private Line (EVPL)
• Replaces Frame Relay or ATM services
• Supports Service Multiplexed UNI (i.e. multiple
  EVCs per UNI)
• Allows single physical connection (UNI) to
  customer premise equipment for multiple virtual
  connections

Related MEF Services Specifications
MEF 6.1
Metro Ethernet Services Definitions Phase 2
Purpose
Defines the Ethernet Services (EPL, EVPL,
E-Line, ELAN,EP-Tree,EVP-Tree etc)
Ethernet Services Attributes Phase 2
MEF 10.1
Purpose
Defines the service attributes and parameters
required to offer the services defined in MEF 6.
Updated from Original MEF 10 in October 2006
Audience
Appropriate for equipment vendors, service
providers, and business customers, since it
provides the fundamentals required to build
devices and services that deliver Carrier
Ethernet. For Enterprise users it gives the
background to Service Level Specifications for
Carrier Ethernet Services being offered by their
Service Providers and helps to plan Ethernet
Services as part of their overall network.
