1. All-Pervasive

Connectivity- Everything,

Everywhere
2.PnP-Plug And Play

Ease Of Use- As the name

suggests, Plug

And Play, Eliminating

User

Hassles

Ready2Go- All PnP devices:

Just Connect

and You Are Up and

Running!



Current Scenario..
Typical Homes of Today have a plethora

of electronic devices, for eg:
A TV
A Computer
A DVD Player
A Mobile Phone
A Portable Media Player(iPOD etc)
A Temperature Regulating System
Common thread among all these devices¦

their embedded nature.
Many have the ability to network, BUT

NOT AUTOMATICALLY!


¢ Potential for Application
Non-PC devices (4 billion

embedded microprocessors in 1999)
Rapidly increasing Internet

adoption rates
Strong uptake in Internet

broadband deployments
64% of U.S. PC homes have

television and PC in the same room
34% of U.S. PC homes have 2 or

more computers
By 2004
27MM networks installed
48.5MM nodes / year run rate
Services a $3BB / yr business



AGENDA
The Dream “ Easy Home Networking
THE What Of UPnP--THE CONCEPT
THE WHY of UPnP--ADVANTAGES
THE HOW of UPnP”WORKING
OBSTACLES TO IMPLEMENTATION
PROPOSED OPTIMIZATIONS
THE WAY AHEAD
A Connected Environment

¢ THE WHAT--- UPnP
UPnP stands for Universal Plug And Play

A set of communication protocols

that provides
¢ INVISIBLE home networking
¢ Framework for SELF-Configuring,

SELF-Describing devices
Salient Features
¢ Leverages existing Internet

technologies such as
TCP/IP, XML,UDP and HTTP
¢ Affordable, mainstream reality

for users
¢ UPnP Strategy
Just send data over the network
¢ No executables
¢ Minimize version issues
¢ Minimize security issues
Allows implementation to be

platform & vendor specific
¢ Be agnostic with reference to

programming language, OS
¢ Update implementation without

affecting interoperability.
Improve performance
Improve capabilities
End User Benefits
No need to install or share

printer on the PC or and manually

connect all devices to the network (no

networking knowledge needed)
Automatically discover

printer/scanner and no need to search

for new imaging devices added to the

network.
Benefits of UPnP
Widely supported networking

specification.
No device configuration, just

Plug and Play.
Small footprint software

component on the device.
Utilizes standard Internet

protocols to talk to LAN.
Independent of OS, language, or

physical connectivity.
Robust and dependable.
UPnP has advantages for

developers and consumers alike.

¢ Drawbacks
¢ Network access .
¢ Large network sizes.
¢ High bandwidth actions.
¢ Users, access rights and

security.
¢ Lack of sophisticated user

interfaces.
¢ Absence of smart services across

devices and networks.
¢ Optimizations
¢ Addition of a control server to

isolate multicast traffic to local

network.
¢ Improved search methodologies.
¢ Concept of user and session.
¢ Specific authorization

procedures for authorization of control

points and devices.
¢ Customized UI based on user

profile
¢ Easy to understand for end

consumer.
¢ Development of mobile device

browsers to support delivery of web

pages over presentation link.
¢ Provision of sophisticated

multi-faceted services.
¢ Introduction of a services

server to manage the services.
¢ Introduction of a UPnP IPv4/IPv6

bridge to support inter-operability.
¢ Bridge converts IPv4 addresses

to IPv6 vice-versa.
¢ Different messages are relayed

to the devices after IP address

conversion by the bridge.

¢ The Way Ahead¦.
¢ Standardization , the lack of

which , proved to be a major roadblock

for connected homes was eliminated by

the publication of the UPnP standard.
¢ AV media servers are some of the

early beneficiaries of UPnP seamless

connectivity.
¢ UPnP protocol stack needs to

ported to other devices to ensure wider

acceptance.
