  1. 1. Carrier Ethernet Services: A Full Range of Testing Tasks
  2. 2. The Challenges of Testing Carrier Ethernet and Triple Play <ul><ul><li>MEF Certification Testing of Carrier Ethernet Services </li></ul></ul><ul><ul><li>Testing of Triple Play data, voice and video application quality, performance and scalability </li></ul></ul><ul><ul><li>SLA Verification of Carrier Ethernet Services </li></ul></ul><ul><ul><li>New Areas of Carrier Ethernet Testing: </li></ul></ul><ul><ul><ul><li>802.3ah Ethernet in the First Mile conformance </li></ul></ul></ul><ul><ul><ul><li>Circuit Emulation Services over Ethernet </li></ul></ul></ul><ul><ul><ul><li>Performance, interoperability and resiliency </li></ul></ul></ul>
  3. 3. MEF Certification Testing of Carrier Ethernet Services <ul><li>MEF 9 specifies tests that determine the readiness of a Metro Ethernet Network (MEN) to deliver various Ethernet Services </li></ul><ul><li>Test requirements are derived from Metro Ethernet Forum Technical Committee documents </li></ul><ul><ul><li>MEF 9 tests are based on MEF 1 which specifies the Ethernet Services Model </li></ul></ul><ul><li>Tests are defined from the point of view of the Subscriber’s equipment that is used to access Ethernet Services </li></ul>
  4. 4. MEF Testing Goals <ul><li>Vendors can refer to MEF 9 test procedures in the development and commercial cycles of their products </li></ul><ul><li>Carriers can use MEF 9 to ensure that the devices or systems they select to deploy in the MEN will result in the successful delivery of Ethernet Services </li></ul><ul><li>Subscribers can attach to the MEN knowing that the Ethernet services they access satisfy criteria based on accepted requirements and test procedures </li></ul>
  5. 5. MEF 9 A Test Specification for Services <ul><li>MEF 9 is an innovative service-oriented test specification </li></ul><ul><li>Defines tests that can be applied to Ethernet Services defined by the MEF </li></ul><ul><ul><li>E-Line Services (EPL, EVPL) </li></ul></ul><ul><ul><li>E-LAN Services </li></ul></ul><ul><li>MEF 9 opens the way for future service-oriented test specifications based on MEF services specifications </li></ul>
  6. 6. Testing Converged Services for Carrier Deployment <ul><li>Increasingly, carriers are deploying Ethernet infrastructures for carrying converged services, e.g., residential triple play </li></ul><ul><li>Carriers must leverage installed infrastructure (copper, cable, etc) especially in Access </li></ul><ul><ul><li>Business services do not terminate on Ethernet UNI </li></ul></ul>
  7. 7. Communications Convergence
  8. 8. Robust SLAs for Ethernet Services <ul><li>Carrier Ethernet Service Level Specifications include </li></ul><ul><li>Bandwidth Profiles and Performance Metrics </li></ul><ul><li>Bandwidth Profiles are associated with the UNI: </li></ul><ul><ul><ul><li>Committed Information Rate ( CIR ) expressed as bits per second. CIR MUST be  0. </li></ul></ul></ul><ul><ul><ul><li>Committed Burst Size ( CBS ) expressed as bytes. </li></ul></ul></ul><ul><ul><ul><li>Excess Information Rate ( EIR ) expressed as bits per second. EIR MUST be  0 </li></ul></ul></ul><ul><ul><ul><li>Excess Burst Size ( EBS ) expressed as bytes. </li></ul></ul></ul><ul><ul><ul><li>Coupling Flag ( CF ) MUST have only one of two possible values, 0 or 1. </li></ul></ul></ul><ul><ul><ul><li>Color Mode ( CM ) MUST have only one of two possible values, “color-blind” and “color-aware” </li></ul></ul></ul><ul><li>Performance Metrics are associated with EVCs </li></ul><ul><ul><ul><li>Frame Delay Performance </li></ul></ul></ul><ul><ul><ul><li>Frame Delay Variation Performance </li></ul></ul></ul><ul><ul><ul><li>Frame Loss Ratio Performance </li></ul></ul></ul>Applications (Voice, Video Data) Services Infrastructure Service Management
  9. 9. Example of Bandwidth Profile Verification at the UNI

Carrier Ethernet Testing Dimensions <ul><li>Scalability </li></ul><ul><li>Services and Bandwidth </li></ul><ul><li>100,000’s of EVC’s </li></ul><ul><li>From Mbps to x10Gbps </li></ul><ul><li>Protection </li></ul><ul><li>50ms Protection </li></ul><ul><li>End to End Path Protection </li></ul><ul><li>Aggregated Line & Node Protection </li></ul><ul><li>Hard QoS </li></ul><ul><li>Guaranteed end to end SLA </li></ul><ul><li>End to End CIR and EIR </li></ul><ul><li>Business, Mobile, Residential </li></ul><ul><li>TDM Support </li></ul><ul><li>Seamless integration of TDM </li></ul><ul><li>Circuit Emulation Services </li></ul><ul><li>Support existing voice applications </li></ul><ul><li>Service </li></ul><ul><li>Management </li></ul><ul><li>Fast service creation </li></ul><ul><li>Carrier class OAM capabilities </li></ul><ul><li>Customer Network Management (CNM) </li></ul>
  11. 11. New Areas of Carrier Ethernet Testing <ul><ul><ul><li>802.3ah Ethernet in the First Mile conformance </li></ul></ul></ul><ul><ul><ul><ul><li>EFMA (Ethernet in the First Mile Alliance) is now part of the Metro Ethernet Forum </li></ul></ul></ul></ul><ul><ul><ul><ul><li>802.3ah includes both PHY layer conformance tests and OAM conformance tests </li></ul></ul></ul></ul><ul><ul><ul><li>Circuit Emulation Services over Ethernet </li></ul></ul></ul><ul><ul><ul><ul><li>MEF Technical Committee is in the process of defining a test specification for Circuit Emulation Services over Ethernet based on MEF 8 </li></ul></ul></ul></ul><ul><ul><ul><li>Performance, interoperability </li></ul></ul></ul><ul><ul><ul><ul><li>Carrier Ethernet can leverage the vast experience the test industry has built up in performance verification of access, aggregation and core infrastructure elements </li></ul></ul></ul></ul><ul><ul><ul><ul><li>MEF aims to extend conformance testing to interoperability testing of services and topologies in the near future </li></ul></ul></ul></ul><ul><ul><ul><li>MEF roadmap for testing </li></ul></ul></ul><ul><ul><ul><ul><li>MEF9 Today </li></ul></ul></ul></ul><ul><ul><ul><ul><li>Traffic Management (Service Quality) in Letter Ballot </li></ul></ul></ul></ul><ul><ul><ul><ul><li>E-LMI (Type II UNI) Mid 2006 </li></ul></ul></ul></ul><ul><ul><ul><ul><li>E-NNI  End 2006 </li></ul></ul></ul></ul>
