TROL TR-069 Client Software

TROL TR-069 Client Software

What is TR-069

TR-069 is a BroadBand Forum (former DSL Forum)
technical specification which defines an application layer
protocol for remote management of customer-premises
equipment (CPE).

For more information see TR-069: CPE WAN Management Protocol.

Why do you need TR-069 support

• Centralized scalable management system

• Possibility to manage a wide variety of residential gateways and other
  network devices (STB, NAS etc.) in the same way

• CPE devices located behind NAT

• Ability to track changes on CPE devices

• Unified and scalable method of software upgrade

• Vendor-specific management methods and configuration parameters
  For more information see MR-230: TR-069 Deployment Scenarios.

TROL benefits

• Design flexibility; no efforts needed to add customer-specific features

• Tunable footprint and RAM usage

• Modularity

  • Multiple data providers each responsible for management of certain hardware
    or software component

  • Flexible logic allows to combine data providers and shape a customer device
    data model

  • Data providers can be reused across customer product line

• Internal memory management to speed up allocations and secure memory usage

• Debug mode with run-time validation of all data structures

• Both ACS and providers data validation according to the datamodel
  specification (type checking, value range, size)

• Run-time modules addition/removal

• Active and passive notifications, diagnostics, periodic Informs

• Integrated file transfer support (HTTP, HTTPS, FTP)

• Strong debug capabilities including CLI interface for precise client control

• Uses Broadband Forum XML data model description

• Ready-to-use data provider for constant values

Components

• Application Core is responsible for application initialization, shutdown,
  configuration files processing, internal events and commands dispatch

• HTTP Server handles TCP/UDP Connection Requests

• CWMP Session manager provides support for CWMP protocol, RPC, Events and
  periodic Informs

• Transfer Manager performs files upload and download

• IPC Manager provides debug interface for communication with
  external applications such as CLI

• Data Providers are responsible for interaction with customer hardware
  or software; each is responsible for a set of TR-069 management variables
  or subtrees

• Data Model Manager performs communication with data providers, generates
  notifications and performs providers data validation

• Persistent Storage Manager reads and stores software/firmware images and
  configuration files into persistent memory, e. g. flash

Portability

• Written in ANSI C

• Single-threaded

• Build system is based on GNU autotools

• Utilize POSIX API (sockets, file access)

• Can run on Linux, FreeBSD, NetBSD, MacOS X, QNX

• Dependencies are gSOAP, libc (uClibc, glibc), OpenSSL (optional), libfetch
  or libcurl, expat

Provided services

• TROL porting to customer platforms

• Integration of TROL with customer’s software

• Validation of customer product for compliance with TR-069 standard

Roadmap

• Replace gSOAP with optimized HTTP/SOAP library

• Support TR-069 Amendment 4 features

• SFTP and TFTP file transfer

• Multicast file transfer

Deployment

The TROL TR-069 Client is used in all new gateways of
Tilgin and has demonstrated good
interworking with ACS used by Tilgin’s partners and clients.
