Summary
Bandwidth demand, costs, required bandwidth
granularities for services, provisioning and OAM are
driving providers to upgrade their networks to NGNs
Wireless backhaul networks will get the much needed
upgrade. Carrier Ethernet is essential to the
transformation to Next Generation Networks
Reliability, interoperability and testing - Cost, resource
and Time challenge
Can be reduced by sharing through IOT and certification facility
NGNs - MPLS and Carrier will co-exist deriving from
each other’s strengths in the Access and the Core

Requirements of an Ethernet based backhaul
network differ from Carrier ethernet networks?
Ethernet based Backhaul Networks have the same
characteristics as Carrier Ethernet networks except the
additional requirements to handle QOS and
Synchronization

Editor's Notes 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
