  1. Web Services and the Devices Profile Jorgen Thelin Program Manager Connected Systems Division JThelin@microsoft.com

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

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

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

  5. Why Web Services • Devices need to interoperate! • Building devices that work with 3rd 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

  6. 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

  7. 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

  8. The Device Profile for Web ServicesScaling WS to limited resource devices

  9. “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 SOAP 1.2 WS-Addressing WS-Metadata Exchange WSDL 1.1 WS-Discovery WS-Eventing Profile Recipe: Staple, Redline, Glue Conformance Claim Action Filter ThisModel Metadata ThisDevice Metadata Policy Assertions Policy Assertions

  10. 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

  11. 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.

  13. Devices Profile Discovery Bootstrap

  14. Typical Devices Profile Message Exchanges

  15. Microsoft Implementations

  16. Vista WS device support • PC Discovery • People Near Me • BITS • Projectors • Integration with current IT systems • Remote diagnostics and configuration • Asset and usage tracking • Speeds flow of meeting • Automatic display and audio settings • Easy to transition between presenters

  17. Vista WS device support • Printers • “plug and play” experience for network printers • Security • Control over who can connect to the printer • Privacy of data sent to the printer • Rich printer status • Scanners • “Plug and Play” experience for network scanners • enable one-button scanning • Secure scan delivery

  18. BuildingYour Device

  19. Building Embedded Implementation • DPWS Protocol components • HTTP & TCP/IP • SOAP and XML parser • TLS/SSL optional for security • WS-* Specifications • WS-Discovery • WS-Transfer • WS-Eventing • Use 3rd Party stacks for rapid development • eSOL

  20. BuildingCustom Clients

  21. 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

  22. 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
