Why Web Services
Increased utility through communication
and cooperation
Web Services = Quality
Enterprise-ready framework
Already proven in the enterprise
Allow your devices to move seamlessly
between SoHo and enterprise environments

“Scales In”
on a machine
“Scales Down”
to devices
“Scales Away”
spans organizations
and geographies
“Scales Out”
by adding
machines

Install Web Services device by name
Future: Enterprise discovery proxy
Browse for PCs, people and Web Services
devices across entire organization
Faster response than NETBios
The Future: Cross
Internet Discovery
Scenario: A user wants to connect to and
print to a printer across the Internet
Trans Network Roaming Discovery Proxy

Based on WS-Discovery
PNRP name resolved by local Discovery
Proxy to remote resource
The Future:
Roaming Devices
Scenario: A user on vacation sends
photos from a hotspot to his family’s
home PC
Trans Network Roaming Discovery Proxy
Tracks devices and clients as they move
across the Internet
Based on WS-Discovery
The Future: Presence
Scenario: A client uses a service
on an intermittent connected device
Discovery Proxy hosts device
presence events
WS-Eventing subscriptions for
device presence
Limited network traffic
Unicast heartbeat
Low power
Device sets heartbeat interval
