History

DSLHome working group started work on DSL CPE/modem auto-configuration years ago

TR-037 DSL CPE Auto-Configuration is an ATM ILMI based auto-

configuration of mainly layer2 (ATM PVCs and their encapsulation)

TR-046 Auto-Configuration Architecture & Framework specifies the

scope for future auto-configuration work


6/56

6

History

TR-64 LAN-Side DSL CPE Configuration Specification was startedbecause of the need for a standard interface for PC-based (LAN-side)install applications. Based upon the UPnP Device Architecture,extensions where defined to meet the LAN-side CPE configurationrequirements.

Differences between TR-64 and UPnP: Separate root device and namespace (co-exists independent from UPnP) No support for eventing (GENA) Digest Authentication per SOAP action Optional use of SSL/TLS (Secure Socket Layer/Transport Layer Security) Transactional semaphores to prevent simultaneous configuration by multiple

control points

Different modeling of some connection models (PPPoE) byLinkType/ConnectionType

IGD datamodel extensions for DSL CPE management

History

TR-69 CPE WAN Management Protocol specification started at the sametime as TR-64.

From the start, the technical approach was controversial and heavilydiscussed. Cisco proposed an SNMP based solution, where as 2Wirecontributed their completely proprietary management protocol.

SNMP was not selected because of security concerns (SNMPv1 and SNMPv2) lack for standard MIBs for DSL CPE management managementagent role: manager connects to agents, where for scalability

reasons the CPE needed to connect to the server

A proprietary protocol was not acceptable, needs to be standards based

Data model ideally common/aligned between TR-64 and TR-69

What is TR-069

TR-069 is a CPE WAN Management Protocol (CWMP), whichwas created by the DSL Forum.

It provides the communication between CPE and Auto

Configuration Servers (ACS). An ACS can manage a device,trouble shoot, configure, upgrade etc.

TR-069 is currently the de facto standard for activation of the

boxes at their first connection to the network.


10/56

10

TR-69 CPE WAN Management Protocol

Starting from a base set of management functionality requirements: Auto configuration and dynamic service provisioning

Software/firmware image management

Status and performance monitoring

Diagnostics

Together with a requirement for using standard protocols/technology

While aligning the management data model with TR-64

A decision was taken to use get/set Remote Procedure Calls on a datamodel instead of functional SOAP actions (like UPnP/TR-64; e.g.

AddPortMapping)


11/56

11

CWMP Protocols

TCP/IP: Transmission Control Protocol /Internet Protocol

SSL/TLS: Secure Socket Layer version 3.0;Transport Layer Security version 1.0

HTTP: Hypertext Transport Protocol version1.1; HTTP POST messages

SOAP: Simple Object Access Protocol version1.1

XML RPC: Remote procedure call encoded inSOAP. All messages exchanged between theCPE and ACS are RPCs.


12/56

12

TR-69: SOAP

The TR-69 SOAP binding on HTTP is not standard.

The CPE sends a SOAP envelope in HTTP request with RPCto server.

Server sends HTTP reply with SOAP envelope containing RPC response

CPE sends a HTTP empty POST request

Server sends HTTP reply with SOAP envelope containing RPC Standard client/server roles are reversed as server is sending requests

(RPCs) within a HTTP reply message

TR-69 is because of this not web services (including WSDL)

compatible/compliant and doesnt work with off-the-shelf SOAP or webserver libraries


13/56

13

RPC

Remote Procedure Calls (RPC) are methods that allow oneprogram to use the services of another program in a remote

machine.

The calling program sends a message and data to the remoteprogram, which is executed, and results are passed back to

the calling program.


14/56


15/56

15

TR-69: Management Sessions

The CPE establishes a connection to the server on a number of occasions: The first time it is installed/connected

On startup

Periodically

When requested by the server

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

server which contains the reason/event for the connection establishment.

The CPE will keep on sending HTTP requests to the server to allow the

server to respond with RPCs until both have nothing more to send.


16/56

16

TR-69: Example message flow

Example management sessionmessage flow

The CPE is responsible for

establishing the session to the

server

The CPE keeps sending HTTP

POST requests during the session.

The session is closed as soon as

both CPE and ACS have indicated

they have nothing more to send

(response or new RPC)

TR-98: IGD Data Model

TR-98 Amendment 1 specifies the Internet Gateway Device data model forTR-69 (which specifies the protocol).

The data model is based upon the initial UPnP IGD model with a largenumber of extensions for DSL gateway provisioning.

It is a hierarchical tree with dot-separated parameter paths, for example:InternetGatewayDevice.DeviceInfo.ModelNameInternetGatewayDevice.DeviceInfo.SoftwareVersionInternetGatewayDevice.ManagementServerInternetGatewayDevice.TimeInternetGatewayDevice.Layer3ForwardingInternetGatewayDevice.Layer2Bridging.Bridge.x.VLANIDInternetGatewayDevice.Layer2Bridging.Filter.x.FilterInterfaceInternetGatewayDevice.LANDevice.x.LANHostConfigManagement.IPInterface.x.IPInterfaceIPAddressInternetGatewayDevice.LANDevice.x.LANEthernetInterfaceConfigInternetGatewayDevice.LANDevice.x.WLANConfigurationInternetGatewayDevice.WANDevice.x.WANConnectionDevice.x.WANIPConnection.x.EnableInternetGatewayDevice.WANDevice.x.WANConnectionDevice.x.WANIPConnection.x.PortMappingInternetGatewayDevice.WANDevice.x.WANConnectionDevice.x.WANPPPConnection.x.Enable

The data model can be addressed by full parameter paths or partial paths


19/56

19

TR-98: IGD Data Model

The following operations/RPCs are supported on the datamodel: GetParameterNames

Retrieve the name of parameters, including object instance numbers

GetParameterValues Retrieve the values of one or more parameters

SetParameterValues Set the values of one or more parameters to a specific value

AddObject Add a new object/entry and return the new unique instance number

DeleteObject Delete an object from the datamodel

GetParameterAttributes Retrieve parameter attributes/meta-data: access rights and event subscriptions

SetParameterAttributes Set parameter attributes: access rights and active/passive event subscriptions

CWMP Interoperability

DSL-Forum regularly organizes TR-69 Plugfest test events where allparticipating CPE devices can test against all participating ACS servers

Thomson participated in previous Plugfest test events.

PD-128 Interoperability Test Plan for TR-069 Plugfests Document with definition of TR-69 tests and their expected outcome

Used as plugfest test events as tests to perform

De-facto reference for TR-69 testing by customers and ACS vendors

Thomson firmware is interoperability tested with and by ACS partners.


29/56

CWMP Interoperability

Each firmware is interoperability tested with the deployed servers atcustomers.

Main protocol interoperability problems in the past where due:

Open HTTP1.1 requirements (e.g. chunked transfer support, number ofcookies...)

Trial and error with new emerging servers

Unsupported PD-128 test cases (parameter attributes...)

TR-69 Amendment 1 specification update with new and even changed (e.g.session termination) requirements

Data model interoperability problems are occurring due:

Hundreds of implemented parameters are not all tested

Focus on customer deployment scenarios, not all combinations of parameters

Thomsons Implementation/Deployment Strategy

Thomson partners with customers on use cases We have an extended data model

No tick-box compliancy of each and every parameter but focus on the use

case enabling ones first

Thomson works together with service provider and ACS vendor toenable use cases (customer driven)

Testing and deploying

Assures the right quality and compliancy

Right approach: Service Providers do not roll out all services immediately

Deployment - Most important use cases

Autoconfiguration and dynamic service activation The initial CPE configuration runs automatically and remotely

Firmware management

Remote updates of the firmware of the boxes in the field

Status and performance control logfile analysis and dynamic messages

diagnostics

connectivity and service control

setvalues: write a value to one or more parameters of an object Rollback for this action issupported at client command level.

getcount: this action returns the number of parameter/value pairs that would be returnedif a getvalues is called with the same arguments. This allows you to determine how muchmemory needs to be allocated to store all parameters or determine the number of objectsof a specific type.

addobject : add an object to the data model.

deleteobject: delete an object from the data model.

subscr ibe: subscribe a client to the MBus event.

unsubscr ibe: unsubscribe a client from the MBus event.
