  1. 1. Carrier Ethernet Services: A Full Range of Testing Tasks
  2. 2. Speaker Introduction Speakers: Akram Ashamalla, Agilent Glenn Chagnot, Spirent Communications Chair: Bob Mandeville, Iometrix
  3. 3. 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>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>Services Interoperability </li></ul></ul></ul>
  4. 4. 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>
  5. 5. 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>
  6. 6. 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>
  7. 7. MEF 14 Traffic Management Test Specifications <ul><li>Carrier Ethernet Service Level Specifications include </li></ul><ul><li>Bandwidth Profiles and Performance Metrics </li></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><ul><li>Bandwidth Profiles are associated with the UNI: </li></ul><ul><ul><ul><li>Committed Information Rate ( CIR ) expressed as bits per second.

  8. 8. Testing Converged Services for Carrier Deployment <ul><li>The Key Market Issue </li></ul><ul><ul><li>Traditional Service providers are in a race with new competitors for deployment of bundled, integrated, triple play services. </li></ul></ul><ul><li>The Deciding Factors </li></ul><ul><ul><li>Data and voice are table stakes, Video (& especially IPTV) is now driving the bundle. Subscriber experience must be equal or better than competitive offerings from the first day of video delivery. </li></ul></ul><ul><li>Deployment and Service Management Challenges </li></ul><ul><ul><li>Service providers are beginning deployment without real practical QoS experience of how the infrastructure, triple play applications and the ultimate services will work as an integrated triple play solution </li></ul></ul>
  9. 9. Ethernet Services & Triple-Play <ul><li>Ubiquitous standards based </li></ul><ul><li>Brings the Ethernet cost model to the carrier network as Ethernet dominates the Access and Metro network </li></ul><ul><li>Technical advantages of layer 2 VPNs etc., </li></ul><ul><li>Improved performance characteristics for Video & Voice </li></ul><ul><li>Lower OPEX and CAPEX for Service Providers </li></ul>What’s the connection? Making Carrier Ethernet an ideal common service architecture for business, residential triple play and wireless backhaul
