Web Services and Devices Profile for Web Services (DPWS)

Web Services and the Devices Profile Jorgen Thelin Program Manager Connected Systems Division [email_address]

What Is Web Services? PCs Servers Services TCP/IP WS Protocols Software talking to Software

What Is Web Services on devices? PCs Devices Servers Services TCP/IP WS Protocols Device Profile for Web Services Software talking to Software on devices

Web Services Scales “ Scales Down” to devices “ Scales In” on a machine “ Scales Up” on large systems “ Scales Away” spans organizations & geographies “ Scales Out” by adding machines

Why Web Services

Devices need to interoperate!

Building devices that work with 3 rd party applications increases value to customer

Build devices that work with Internet services could add revenue streams

HTML and browsers are limited

Browsers can’t automatically collect data

Browsers can’t automatically control devices

Custom protocols are costly

Quality

WS protocols will be long-lived

They’re general purpose and are being adopted by many large companies

Enterprise-ready framework

Already proven in the enterprise

Allow your devices to move seamlessly between So-Ho and enterprise environments

Multi-party reviews and interop events for each spec

Security

Integrity, Confidentiality

Channel-Based (TLS)

Message-Based (WS-Security)

Secure content

Scenario – print job content securely over the wire, allowing devices to be implemented at secure sites

Secure communications

Scenario – secure check printing

The Device Profile for Web Services Scaling WS to limited resource devices

Profile Recipe: Staple, Redline, Glue

“ Staple”

Pull relevant specs into scope

“ Redline”

Add constraints on use of those specs

“ Glue”

Define missing bits between specs

Some will migrate back into specs

Device Profile for Web Services

Lightweight subset of WS specifications

Described in Device Profile for Web Services (DPWS) specification

Security based on SSL/TLS

Shipping in Windows Vista and Windows CE

Device Profile for Web Services

Built on the foundation of industry standard Web Services

Extensible Markup Language (XML)

Simple Object Access Protocol (SOAP)

WS-Discovery, WS-Addressing… (WS-*)

Web Service Definition Language (WSDL)

Message Transmission Optimization Mechanism (MTOM)

Developed using the WS workshop process

Co-Authors include Intel, Canon, Ricoh, and Lexmark.

Use 3 rd Party stacks for rapid development

eSOL

Building Custom Clients

Building WS on devices in WCF

Indigo is now Windows Communication Foundation

Managed code in C# for rapid development

WCF Samples include WS-Discovery and SOAP over UDP transports.

Interop tested with many industry stacks

Great rapid prototype environment for both clients and devices

Building WSD Client/Server in Native Code

WSDAPI.DLL is the foundation for Printer and Projector support.

Abstracts WSD for the application developer

WSD Client or Service

Integrated with Plug and Play-X (PnP-X)

Device Class component

WSDL definition to drive codegen tool

Codegen output becomes part of your application

Application software

Write to codegen generated functions
