  • A look at the Internet growthWorldwide population : is around $6B and today there are around $1.6B users a penetration of 24.5% , with a 360% growth over the last 9 years but the picture is deceptive since a lot of the users are on shared connections or dial up, in Internet CAFEs , they are not getting kind user experience that is needed . Internet is no longer a luxury it is a neccessity to enable to keep pace with the information explosion…
  • Mobile Backhaul is moving towards Internet Protocols as they move away from legacy transport technologies, for cost and operational reasons
  • Mobile Backhaul is moving towards Internet Protocols as they move away from legacy transport technologies, for cost and operational reasons
  • This slide elaborates some more on the OAM subject how the inter-carrier interface will be handled in terms of OAM.As you can notice the PE to PE connection is a NNI (Network-2-Network ) interface
  • MEF is standardization the CE through Frameworks for testing, implementation agreements and has defined elements and services ,As you can see in this diagram
  • IP infusion as a software manufacturers ensures that its software solutions for Networking meets the compliance requirements and as such implement MEF standards and then uses MEF test suites in its 3 world-wide lab in USA, China and India.
  • Standards are evolving in these areasLike 802.1ag or 1731 from ITU-THowever how to test all the equipments meet the criteria
