What Is Web Services for Devices? PCs Devices Servers Services TCP/IP WS Protocols Device Profile for Web Services

Web Services on devices Protocols for consuming and controlling services on network connected devices Built on industry standards defined in the Device Profile for Web Services (DPWS) WS-* Extensible Markup Language (XML) Simple Object Access Protocol (SOAP) Web Service Definition Language (WSDL) Message Transmission Optimization Mechanism (MTOM) Lightweight subset of WS Specifications Security based on SSL/TLS Shipping in Windows Longhorn

The Value Of WSD Custom protocols are costly Expensive to develop and maintain Limited 3 rd party applications for device Distracted device vendors from key business area Poor integrated experience in Windows Opportunity for Device manufactures to innovate Build on top of Windows infrastructure Devices vendors can concentrate on building great devices Innovate in core business areas Interoperate with other parties Build devices that work with 3 rd party applications Build devices that work with Internet services

The Value Of WSD Opportunities exist for new revenue streams Create secure end-to-end applications that provide great end user benefits Directly sell services or supplies to your customers From Consumables, toner Extended warranty Product upgrades To Data services Storage services And more Integrate with existing Web Services AmazonMappoint And many others!

The Value Of WSD Gain a competitive advantage Create new markets Opportunity for leadership in new markets Access enormous ISV and developer base Simplify the customer experience!

Examples Of WSD Network Printing and Scanning Network Projectors and Displays Building Control

Building A WSD Printer Tali Roth Lead Program Manager Digital Documents microsoft.com Microsoft Corporation

Printing And Imaging Problem Set Many scenarios to solve for network printers and scanners Discovery How can you get a “plug and play” experience? Security How can you enable real security? Control over who can connect to the printer Control over data sent to the printer Secure wireless access Control and Response How can you configure your driver? How can you know when your job has finished printing? How can you get rich status to enable a status monitor or ordering applet? How can you enable one-button scanning? Consistency How can you use one solution for all the functions on your multi-function printer?

Web Services Solution Web Services solves these problems! WS-Discovery enables “plug and play” for network devices WS-Security enables security scenarios WS-Eventing enables auto-configuration, rich status Device Profile for Web Services enables consistency throughout all classes of devices

Writing The Windows Device Protocols (WSDL) Microsoft has written Print and Scan Protocols (WSDL) Both are completely extensible Can extend the protocols Can extend new print port monitor (WSDMon) Independent Hardware Vendors (IHVs) can also create their own protocols that run over Web Services Microsoft defined the print and scan WSDL and evolved the specification based on IHV feedback Plugfests and continuing vendor engagements planned to get additional feedback Will be delivered in the Windows Driver Kit

Status Of Vendor Adoption Microsoft is working with many tier 1 printing and imaging IHVs Print specification currently at v0.3 Scan specification currently at v0.2 Feedback very positive so far – IHVs see value proposition of Web Services for Devices Six hardware implementations were brought to first print plugfest held in February 2005 See resources for information on how to get a copy of the Print and Scan protocols

Installing A WS-Based Printer Key Points Ease of installation Automatic driver configuration True end of job support Shown using Canon imageRUNNER with Color MEAP Technology

Building A WSD Projector Todd Manion Program Manager Collaboration Technologies microsoft.com Microsoft Corporation

Customer Pain Points With Today’s Projectors Expensive to manage and maintain No integration with current IT systems Security and upgrade management Remote diagnostics and configuration Fault prediction Asset and usage tracking Complicated to use Each presenter must adjust display and audio settings Slows flow of meeting Play musical chairs to sit close to the projector Difficult to transition between presenters Impossible to provide consistent, better presentation management tools

Web Services Helps Solve These Problems WS Allows for remote configuration WS-Discovery enables “plug and play” Makes projectors easy to find and use Makes projectors easy to find and use WS-Eventing enables auto-configuration Easy to setup displays and audio setting Easy to setup displays and audio setting

Network Projection

Web Services Residential Device Control Eric Eichensehr Chief Technology Officer Exceptional Innovation

Web Services in Building Control Industry moving to IP based connectivity and control DPWS is the right protocol for residential device control WS-Security enables security scenarios WS-Eventing enables rich status Device Profile for Web Services enables consistency throughout all classes of devices

Residential Device Control Key Points Ease of installation Integrated device control Device eventing status to host

DPWS Call To Action Integrate Web Services into your devices to support ease of discoverability and use Participate in the DPWS interops and workshops Work with Microsoft and your industry to define WDPs (WSDLs) for your device class Build new businesses in a world of connected devices!
