Market and business drivers

New opportunities and pain points from the connected world

For Service Providers For consumer electronics vendors

5

Why now?

• 800 million TR-069 CPE WAN management protocol devices

• Explosion of connected devices

• Leveraging and building on knowledge gained

• Time for user services and improved access control

• Demand for improved support of pub-sub deployment models

6

User Services Platform Key Features

• Flexibility

• Scalability

• Standardization

• Security

The User Services Platform is made of a network of Controllers and Agents to allow Applications

to manipulate Service Elements

An Agent exposes Service Elements to one or more Controllers.

It can represent Service Elements on a device directly…

Or it can represent Service Elements on other devices through the proxy mechanism.

An application could use a Controller to manage a provider controlled system, like in today’s TR-069

Auto-Configuration Servers.

Or to act as a user portal in the Cloud, on a gateway, or accessed through a smart phone.

Or as part of an automated smart home or managed Wi-Fi system.

Protocol stack• USP records

• Integrity, security

• Message transport agnostic• Local, cloud, and mobile use cases

• Protocol buffers encoding• Lightweight, schema based

• Reduced, flexible message set• Easily extensible

TCP or UDP(depending on MTP)

TLS/DTLS(depending on MTP)

Message Transfer Protocol (CoAP, STOMP, WebSocket)

USP Record(Protobuf encoding with

schema usp-record.proto)

USP Message(Protobuf encoding with schema usp-msg.proto)

10

Comparison with TR-069User Services Platform (USP) TR-069 (CPE WAN Management Protocol)

Message TransferProtocol

CoAP (LAN)WebSockets (Fixed-WAN)STOMP (WAN / Mobile)

HTTP

Data encoding Google Protocol Buffers (binary wire format) SOAP / XML (text wire format)

RPC structure CRUD + Notify + Operate (general data model command execution mechanism)

CRUD + Notify (via Inform RPC, Events, and event specific RPCs) + several RPCs related to data model operations (Schedule, Upload, Download, etc.)

Communicationsparadigm

Always-on/always-available communications channel established at device start-up allowing for the free flow of messages

Short-lived sessions triggered by external events (timing, schedule, boot, wake-up, connection request, etc.)

Management server Multiple management servers are allowed at the same time without restriction of location (LAN, Fixed-WAN, Mobile)

A single management server at any given time with bootstrap logic/configuration

Security DTLS/TLS message transport protocol security, controller trust establishment procedures,access control list mechanism, end-to-end application level security/encryption mechanism

TLS message transport protocol security, security through obscurity (CPE can only communicate with known ACS URL when it receives a connection request)

11

Comparison with other management solutionsUser Services Platform WebPA



WebSockets

Data encoding Google Protocol Buffers (binary wire format) MsgPack (binary wire format)


RU-Only (static data model, no commands)

Communications paradigm Always-on/always-available communications channel established at device start-up allowing for the free flow of messages


Management server Multiple management servers are allowed at the same time without restriction of location (LAN, Fixed-WAN, Mobile)

A single management server

Security DTLS/TLS message transport protocol security, controller trust establishment procedures, access control list mechanism, end-to-end application level security/encryption mechanism

TLS message transport protocol security

12

Comparison with other IoT management/control solutions

User Services PlatformGeneric Cloud Solution (MQTT based, for example)



Single message transport that is not ideal for all use cases

Data encoding Google Protocol Buffers (binary wire format) Undefined


RESTful only – additional RPCs not standardized

Communications paradigm Always-on/always-available communications channel established at device start-up allowing for the free flow of messages


Service element Standardized elements based on Device:2 data model from TR-069

Undefined – objects and messages are non-standard

Security DTLS/TLS message transport protocol security, controller trust establishment procedures, access control list mechanism, end-to-end application level security/encryption mechanism

TLS message transport protocol security if implemented, no standardized access control, communications through a proxy can be snooped

13

Why USP enables more• Multi-tenant management & control

– enables multiple operators to manage and control the same devices at the same time

• User management & control– enables the end user to manage and control their own devices in conjunction with the operators

• Privacy – defines a Role-based Access Control permission scheme allowing different roles to be assigned to different

controlling endpoints

• Robust communications – provides RESTful operations that are forgiving to the variations inherent across the breadth of CPE

• Secure communications – provides both protocol-level encryption and application-level security to ensure data and interactions are

protected

• Fast adoption and coexistence– built upon the Device:2 root data model (TR-181 Issue 2) to provide an easy migration path for existing

implementations; can coexist with TR-069 on the same device to provide an alternate management channel
