  3. Terms • CPE – Customer Premise Equipment or the device that is being managed. Examples: Wireless Gateway Router, VoIP Digital Adapter, NAS (Networked Attached Storage) Drive, Settop Boxes, etc. • ACS – Auto Configuration Server, management server for CPE. Part of the Service Provider’s OSS / BSS (Operational or Billing Support Systems) • XML – Extensible Markup Language. Set of encoding rules that is both human and machine readable. • SOAP – Simple Object Access Protocol, messaging framework for web services, uses XML as its message format. • RPC – Remote Procedure Call, built-in procedure that can invoke another process on a remote computer/network. • Data Model – Set of objects defined for management of a CPE. • SNMP – Simple Network Management Protocol, protocol for managing devices on IP network. • STUN – Simple Traversal of User Datagram Protocol through Network Address Translators (NAT)

  4. What is TR-69? • Technical Report defined by Broadband Forum • XML SOAP Protocol • Specification to remotely managed end user devices • Enables communication between Customer Premise Equipment (CPE) and Auto-Configuration Server (ACS) • Base Management Functions: • Auto-Configuration • Dynamic Service Provisioning • Software/Firmware Image Management • Status and Performance Monitoring • Diagnostics

  5. TR-69 Architectural Framework OSS/BSS Managed LAN Device Scope of CPE WAN ManagementProtocol (CWMP): ACS Southbound Interface Policy Managed LAN Device Call Center Managed Internet Gateway Device Auto-Configuration Server (ACS) Managed LAN Device ACS Northbound Interface

  6. TR-69 Remote Management of Home Devices on Private Network STUN Server STUN Binding Messages IPTV STB Wireless Home Gateway Router Inform Messages ACS VoIP Digital Adapter • STUN Server enables ACS to send Connection Requests to devices in customers home that reside on a private network • STUN protocol used to provide public address and port to ACS

  7. TR-69 Extensions • What can TR-69 be used for? • Manage VoIP Analog Telephone Adapters, [DSL] Modems, Residential Gateways, IP Settop Boxes • Extensions define data models for different devices: • TR-98 – gateway devices (DSL modems w/ built in routers) • TR-181 – Device Data Model • TR-104 – VoIP devices • TR-106 – Baseline data model structure • TR-110 – reference model for VoIP configuration • TR-111 – encompasses remote mgmt (now obsolete, requirements incorporated in TR69 Annex G)

  8. TR-69 Advantages/Disadvantages Advantages • Device Configuration, troubleshooting, firmware upgrades, user management, monitoring. • Enables Service Provider to offer dynamic services from a centrally managed instance. • Reduces truck rolls/support calls by ability to managed devices with more granularity, proactive monitoring, and automated processes. Disadvantages • Must cross several layers of protocols and methods that must interoperate • Interpretation of the Technical Report by various manufacturers differs, no standard certification.

  9. TR-69 vs SNMP • SNMP • SNMP is a simple method to monitor and receive traps for our devices • Uses Community String (SNMPv2) for authentication • Limited to the demarcation device within a subscriber’s home. • TR-69 • CPE Wan Management Protocol is designed to provide a high degree of security and is scalable. • Basic security allows for less robust CPE implementations • Greater security for advanced CPE implementations • Prevents tampering with the management [transactions or] functions of a CPE and/or ACS • Prevent theft of service

  10. TR-69 Protocol Stack

  11. TR-69 Call Flow

  12. Sample Remote Procedure Calls List • Inform • GetParameterAttributes • SetParameterAttributes • GetParameterValues • SetParameterValues • AddObject • DeleteObject • Reboot • Download • Upload • FactoryReset

  13. ACS ScreenShots Replacement Gateway receives default gateway’s configuration or last saved configuration

  14. ACS ScreenShots Configure NAS device for Web access and connectivity to home devices

  15. ACS ScreenShots Online gaming performance degradation. Able to view statistics of packets sent/received, errors.

  16. ACS ScreenShots Access WebCam interface for configuration & setup

  17. ACS ScreenShots Management Console to define policies

  18. TR-69 – Actively Used by Other MSO • Bell Canada • AT&T • Telefonica • China Mobile • Frontier • Telus • CenturyLink • Hughes • Qwest

  19. TR-69 – Estimated Timelines Approximately 13% of TR-98 supported on Motorola CPE SBG6580 InterOp with some Gateway Vendors CablelabsWifi Provisioning Framework Data Model still being defined Q3-Q4 2011 Q1 2012 Q2 – Q3 2012 Q3 – Q4 2012 Q1 2013 Vendors contacted Approximately 8% of TR-181 supported on SMC CPE D3GN4 Cablelabs members considering TR69 beyond WiFi GW Cablelabs TR69 test with other vendors for Wifi GW
