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

Motivations for a Multi-Service Architecture - I

� 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

� 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

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.

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

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

Broadband Forum G-PON ONU Certification Program

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

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

� Having BBF.247 certified ONUs insures that vendors’ products are easily integrated by any G-PON OLTmanufacturers
