3 Introduction The BBF has been driving the evolution of Broadband Network Architecture for the last 14 years this has involved all the major stakeholder in the industry BBF Technical Reports and Interoperability Programs are playing a critical role in helping the industry face the new challenges Choices between options have to be made, solutions have to be end-to-end and they have to be proven Interoperability, manageability and integration in operators environments are key requirements BBF is open to all technologies and helps convergence 3

4 Challenges faced by Network Operators 4 Providing Multi-Service support Moving from ATM to Ethernet based Access New Business Requirements & service models Multi-Service Broadband Architecture Introducing Fixed- Mobile convergence Augmenting xdsl with Fibre access Providing Cloud services

5 Motivations for a Multi-Service Architecture - I 5 Support for different customer types, markets and services: residential, retail, business, wholesale, fixed, mobile, cloud/virtualized services over a common network architecture Simplification of network architecture: an end-to-end architecture based on IP/MPLS and Ethernet with a well-defined migration path Multi technology Access support: xdsl, Ethernet, GPON, EPON, FTTdp, Microwave wireless, legacy voice, wavelength access for business customers, TDM circuits Multi-Edge support: the ability to source traffic to a given subscriber from multiple, different, Service Edges Enhanced Scalability: moving IP Edge Nodes closer to customers allows the connection of more customers to the aggregation network

6 Motivations for a Multi-Service Architecture - II 6 Enhanced availability: use of OAM and an appropriate control plane for automatic protection and/or restoration Seamless connectivity:integration of access, aggregation and core networks Operational enhancements:migration to a converged packet based access and aggregation network can improve the end-to-end provisioning process by minimizing touch points Enhanced support for Wholesale services:to meet regulatory requirements (e.g. Active Line Access) and support non-vertical business models Fixed-Mobile Convergence (FMC): to support a single handheld device for both fixed and mobile access

7 Roles played by BBF Reports 7 Providing Multi-Service support TR-101 Moving from ATM to Ethernet based Access TR-101 TR-221 TR-145 New Business Requirements & service models Multi-Service Broadband Architecture TR-203 TR-144 Introducing Fixed- Mobile convergence WT-300 TR-291 WT-178 Augmenting xdsl with Fibre access SD-302 TR-156 TR-200 TR-167 Virtualization WT-317 WT-301 WT-328 SD-313 WT-326 WT-340

8 Fiber integration in triple play deployments Replicate over fiber the multi-services architecture adopted over DSL Leverage platforms and processes used in existing deployments Ethernet interfaces (U/V/W) similar to TR-101 TR-069 and OMCI are perfectly complementary for customer device management External interfaces shall be agnostic to particular access technologies - as much as possible.

9 Flexibility to support various business models and device types PON used in access or aggregation networks Single Family Units, Single Business Units, Multi Dwelling Units, Multi Tenant Units Ethernet or DSL last drop ONU and Routing Gateway as separate devices or integrated into one box Maximize commonality of architecture to reduce integration costs and guarantee interoperability

10 OLT-ONU Interoperability Allow OLT and ONU to be provided independently By different vendors By different operators Ultimately by end users themselves (retail model) Functional cut between PON OLT and ONU specified by BBF TR-156 (G-PON access), TR-167 (G-PON aggregation) and TR-200 (E-PON). The BBF.247 certification test plan eliminates OMCI implementation options for supporting TR-156 and TR- 167 architectures: creates true multivendor interoperability.

11 TR-156 and TR-200: GPON and EPON access The entire PON system performs the role of an Access Node as specified by TR-101 U and V reference points remain unchanged Aims to integrate seamlessly into broadband service providers deployments 11

14 Broadband Forum G-PON ONU Certification Program Expediting market deployment of fiber networks

15 The Broadband Forum G-PON Certification Program Industry s first G-PON certification program, based on test plans developed by the Broadband Forum with support of FSAN and ITU-T Open to G-PON ONU products with Ethernet interfaces and is based on the TR-247 test plan Proves conformance to TR-156 using OMCI as defined in the ITU G.988, which are the most critical standards for interoperability ONUs with other profiles and types of interfaces /features will be addressed in the very near future, along with extensions for XG-PON 1 ONU/OLT Interoperability Test Plan in development, and the ONU Conformance Certification will be a requirement to participate in the Interoperability test program 15

16 Why have a Certification Program? Internationally respected organization with 17 years of interoperability program excellence Service Provider driven test plans/required in global RFPs Shortens test cycles. Offers single round of universally recognized tests-decreasing costs Helps vendors competitively position products globally Independent standards based certification creates a common language Eases the launch of products and expedites fiber deployments 16 Having BBF.247 certified ONUs insures that vendors products are easily integrated by any G-PON OLT manufacturers

17 G-PON certified products! Each company below has a product that is now certified 17

18 Program basics Program open to Broadband Forum members only Certificate granted to compliant products (passing all mandatory and conditional mandatory tests) Allowed to use BBF certification logo Option for companies to have their certified products listed on Broadband Forum s global registry Testing is available through approved independent testing agencies LAN laboratories (facilities in USA, China and France) 18
