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, 업그레이 드 등을 관리할 수 있도록 조정자 역할을 하게 해준다.

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

TR-069 Protocol

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

TR-069 Security Mechanism SSL/TLS Transaction의 기밀성 제공 Data integrity 제공 Authentication 제공 HTTP Authentication based on shared secrets. Shared secret = <OUI>-<Product. Class>-<Serial. Number> <e. g. 012345 -STB-0123456789 > <e. g. 012345 -0123456789>

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.
