Introduction to Ethernet Business Services

To the end users, Carrier Ethernet appears as a globally available business service, reaching locations serviced by high speed metro Ethernet fiber, DSL, cable, copper and wireless and even over traditional E1 lines.

The service is delivered as point-to-point (E-Line) or multi-point (E-LAN) over dedicated or virtual connections. It’s consistent, standardized and available worldwide in bandwidths from 1mbps to 10Gbs. It has specific profiles for variable bandwidth and QoS demands, making it ideal for data, voice and video. It brings the cost model of Ethernet to the wide area network together with ubiquity and scalability.

Why Have Ethernet Become So Successful, So Quickly?

Deployment of Carrier Ethernet services had raced to an astounding $12bn by 2008* with predictions of more than $30bn by 2012. This is driven by the following benefits to end users (IT, network and applications departments) and service providers alike.

Scalability, Ubiquity and Reach
  • Global availability of standardized services independent of physical access type dramatically reduce complexity and cost

Performance, QoS and Suitability for Convergence
  • Inherently Ethernet networks require less processing to operate and manage and operates at higher bandwidth than other technologies
  • Low latency and delay variation make it the best solution for video, voice and dataCost Savings
  • Carrier Ethernet brings the cost model of Ethernet to the wide area network
 
Control, Simplicity, Familiarity
  • IT departments manage Ethernet networks every day and now are in control of their IP routed networks, worldwide
Expediting and Enabling New Applications
  • Accelerates implementations with reduced resources for overburdened IT departments
  • Enables new applications requiring high bandwidth, and low latency that were previously not possible or prohibited by high cost
Consistency, Predictability and Risk Reduction
  • These are all enabled by standardization and by the MEF Certification Program (see next page)

Reliability and Protection

  • Provides carrier-class failover and availability
Flexibility, Adaptability
  • Carrier Ethernet enables flexible service agreements, ideal for applications such as site-to-site access which by the nature can have unpredictable and varying bandwidth requirements
