Carrier Ethernet Network




MEF Mobile BackhaulMarket Dynamics

  • Introduce MEF Mobile Backhaul Specification
    • A standardized implementation guide
  • Describe the opportunity for service providers:
  • Existing Mobile Carriers driven by demand & next gen services
  • New Revenue opportunities for wire-line service providers
carrier ethernet for mobile operators
Carrier Ethernet for Mobile Operators
  • Ethernet is the accepted solution,but there are concerns to understand
    • What are these concerns?
    • How does the MEF Mobile Backhaul Agreement address them?
    • What is its scope?
  • What are the analysts saying?
  • Carrier Ethernet for Mobile Carriers

Michael Howard, principal analyst at Infonetics Research

“Ethernet is seen as the only solution for next generation MBHnetworks … legacy technology can’t scale … surge in spending on Ethernet over microwave …”


Ethernet Options Solve Backhaul Cost Problem

PDH and ATM over PDH vs New Wireline:

Mobile First Mile Backhaul Service Charges per Connection

Stay on PDH


Backhaul Service Charges per Connection

Or, move to Ethernet


  • PDH (T1/E1 etc.) costs climb directly with bandwidth
  • Ethernet wireline costs grow incrementally with large bandwidth increases (Ethernet, DSL, PON, cable)
  • New IP/Ethernet wireline options to satisfy the #1 investment driver: operational cost savings

Carrier Ethernet for Mobile Backhaul
  • NPRG forecasts Carrier Ethernet services gain traction in 2009, driven by accelerating 3G cellular data plan penetration and mainstreaming of broadband wireless services (e.g., “Clear” WiMAX from Clearwire)
  • Revenue gains for Ethernet providers could be dramatic, as NPRG forecasts solid double-digit CAGR for the overall backhaul market through 2013
  • In 2008, notable contract wins were scored by Ethernet providers in the Midwest, New York, Florida, and California; additional wins are on the horizon for 2009

Scope (1): Operational Experience

Carrier Ethernet for Mobile Carriers

  • The Mobile Backhaul Implementation Agreement scopes Ethernet OAM requirements
  • Ethernet OAM allows monitoring of Ethernet services
    • Verify connectivity
    • Identify configuration faults
    • Measure service performance
    • Loop back testing
    • Further developments in later phases
  • Draws on and includes existing standards
    • IEEE 802.3ah : Link OAM
    • IEEE 802.1ag : Connectivity Fault Management
    • ITU-T Y.1731 : Performance Monitoring
  • Class of Service requirements aligned with 3GPP and WiMAX recommendations
    • From high to low priority:
    • Conversational class (voice, whether IP- or TDM/ATM-based)
    • Streaming class (streaming video)
    • Interactive class (web browsing)
    • Background (non-interactive data)
    • Potentially synchronization and other control traffic in a separate class
scope 2 synchronization
Scope (2): Synchronization
  • Migration to all packet networks means loss of TDM clock source
  • Components of sync
    • Frequency (2G, 3G, 3.5G)
    • Phase (4G in some cases)
    • Time of Day
  • Packet based
    • Out-of-band (GPS, legacy E1 clocking) is outside of scope
    • Packet based methods are in scope for Phase 1
      • Synchronization quality requirements reference the ITU G.8261 standard
      • The IA is agnostic to specific methods/implementations like adaptive clocking, RTP-extended adaptive clocking, IEEE1588 etc.
    • Synchronous Ethernet in scope for future phases
    • Eliminates the cost and need for retention of T1/E1 circuit solely for synchronization

Carrier Ethernet for Mobile Carriers

scope 3 reliability and availability
General recommendation for Fault Protection:

Required at network controller

Not mandatory at base station

Implementations will be driven by application needs, customer preference, and cost

Scope (3): Reliability and Availability

Carrier Ethernet for Mobile Carriers

scope 4 evolution support
Scope (4): Evolution Support

MBH Generic Interworking Function (GIWF)

User to Network Interface (UNI)

  • Supports Multiple Generations of Mobile Backhaul
    • Scalable consolidation enables backhaul of any combination of 2G/3G voice and data traffic over a single CE RAN
    • Designed to support 4G/LTE networks

  • MEF Implementation Agreement specifies 4 use cases
    • Allow migration or immediate transition to Carrier Ethernet separating backhaul of voice and data or integrated mobile data and voice in a Carrier Ethernet network.

Example: Use Case 1a: Hybrid Offload – data exchanged using Carrier Ethernet, voice transport remains with legacy network only as long as necessary

The Generic Inter-working Function (GIWF) provides functionality that allows RAN CE devices with a Non-Ethernet I/F to send traffic over an Ethernet UNI

a new opportunity for wire line service providers
A New Opportunity for Wire-line Service Providers
  • Opportunity
    • The new agreement provides a new wholesaleopportunity to leverage existing wire-line backhaul infrastructure and capacity
    • Driven by the migration of mobile technologies to Ethernet backhaul
  • The MBH Implementation agreements helps wholesalers
    • It states the requirements
    • Includes specific Service Level Specifications that are required for transport of Mobile Backhaul across wire-line backhaul
  • Other deliverables for wire-line wholesalers
    • Back-up slides at the end of the deck contain further business case and Mobile Backhaul fundamentals for these wholesale opportunities
  • New Revenue opportunities for wire-line service providers
mef mobile backhaul phased development
MEF Mobile Backhaul Phased Development
  • Phase 1 (The first Specification: MEF 22 January 2009)
    • Ethernet Virtual Connections (EVC) span a single MEN.
    • Synchronization is either delivered outside of the Ethernet transport network or using a packet based method that is transparent to the MEN*, e.g. treated as standard Service Frames.
    • The mobile standards that are considered are: GSM, WCDMA, CDMA2000, and WiMAX 802.16e.
  • Later phases (for further study)
    • Ethernet Virtual Connections (EVCs) spanning arbitrary number of MENs.
    • Other synchronization methods.
    • Other mobile standards, such as LTE (Long Term Evolution).
    • Extended architecture scope, e.g. mobile core network and additional mobile network reference points.

* For consistency Carrier Ethernet networks are referred to Metro Ethernet Networks (MEN) in the specifications

  • Mobile Operators must upgrade their backhaul to Ethernet
  • MEF Implementation agreement defines a common approach for all Service providers
  • Carrier Ethernet in the RAN opens new opportunities for fixed line operators
  • The migration to Ethernet RAN has started
  • Carrier Ethernet mandated for 4G/LTE
