  1. TR-069 박용정

  2. TR-069 • TR-069는 DSL Forum에서 정의한 CPE WAN Management Protocol (CWMP)이다 • CWMP는 CPE (Customer Premise Equipment) 와 ACS (Auto-Configuration Server)사이에서 ACS가 CPE의 설정, 업그레이드등을 관리할 수 있도록 조정자 역할을 하게 해준다.

  3. TR-069 기능 • Auto-configuration and dynamic service providing • Initial CPE Configuration • Re-provisioning at any subsequent time • Software/firmware image management • Version identification • File download initiation • Notification of the success or failure of a file download • Status and performance monitoring • Log file, and dynamic notification • Diagnostics • Connectivity and service issues

  4. TR-069 Protocol

  5. TR-069 Security goal • Prevent tampering with the management functions of a CPE or ACS. • Provide confidentiality for the transactions that take place between a CPE and ACS. • Allow appropriate authentication for each type of transaction. • Prevent theft of service

  6. TR-069 Security Mechanism • SSL/TLS • Transaction의 기밀성 제공 • Data integrity 제공 • Authentication 제공 • HTTP • Authentication based on shared secrets. • Shared secret = <OUI>-<ProductClass>-<SerialNumber> • <e.g. 012345-STB-0123456789 > • <e.g. 012345-0123456789>

  7. TR-069 RPC Methods • Optional RPC’s • CPE Methods • Upload • FactoryReset • GetQueuedTransfers • ScheduleInform • SetVoucers • GetOptions • ACS Methods • RequestDownload • Kicked • Required RPC’s • CPE Methods • GetRPCMethods • SetParameterValues • GetParameterValues • GetParameterNames • SetParameterAttributes • GetParameterAttributes • AddObject • DeleteObject • Download • Reboot • ACS Methods • GetRPCMethods • Inform • TransferComplete

  8. TR-069 Connection Establishment • The CPE establishes a connection to the ACS on a number of occasions: • The first time it is installed/connected • On startup • Periodically • When requested by the ACS • Whenever particular parameter values change (via Connection Request) • When a file transfer is complete (e.g. after firmware upgrade) • When a diagnostics test is complete • On each connection establishment, the CPE sends the Inform RPC to the ACS which contains the reason/event for the connection establishment.
