Overview

• Examples
• Enablers, technology
• Options (opportunities) of embedded internet
• Complications
• (Trends)
• Conclusion

3
DVD player (Philips Research)

• Bug fixing
• New version of software

4
Feeding the fish...

• Monitor
• Control

5
Using a regular camera

• Take pictures
• Extract and change film
• Bring film to shop for development
• Pick up developed material
• Repeatedly
• View pictures may require projector/TV
• Archive the pictures
• Take pictures out of archive

6
Using a digital camera

• Take pictures
• Extract and change storage medium
• Load pictures into larger archive
• Repeatedly
• Take pictures out of archive
• View pictures requires computer/TV
• Archive the pictures

7
Recent developments

• Bluetooth
• wire-less, short-range (/- 10m)
• connects groups of at most 8 devices
• acts as a digital link (transports bits)
• GPRS
• wire-less, long-range as GSM
• connects directly to the internet
• acts as a packet link (transports IP packets or
  X.25)

Requirements

• Solving the last-meter problem
• standardization fire-wire, usb, ethernet, LON,
  bluetooth, hiperlan, dect, GPRS
• automatic wire-less connection bluetooth, dect?,
  hiperlan or long distance GPRS
• Standardization of information transport
• protocol IP, IP, IP

Technology

• Hardware
• Evolution wire for long distance, wire-less for
  short distance
• Need to reconcile different interfaces gateway
• Software
• As soon as it speaks IP, it can communicate with
  the rest of the world and benefit from existing
  internet technology
• (IP - TCP/UDP - FTP - HTML - JAVA)

11
Options of embedded internet

• Telemonitoring and
• control
• Software download
• Intelligent behaviour

12
Option telemonitoring en control

• On-off control for energy and emergency
• Adjustment of process-control parameters
• Status monitoring and data collection
• billing
• statistics
• quality control
• production data
• fleet management
• remote diagnostics
• back-up and recovery
• planning of maintenance

Different value for user/owner and
manufacturer/retailer
13
Monitoring quality of water(Turnkiek)
14
Option software download

• Bug fixing
• Customisation
• Product family architecting
• Software component marketing
• Selling new features in software
• Incremental delivery of software
• perhaps platform independent code
• uploads platform independent GUI
• general follow Internet developments XML,
  Java, VRML, facial and voice-based
  user-interfaces, etc.

Different value for owner and manufacturer
15
Platform independent

• Code
• Graphical user interface

Remote user

• Embedded system

embedded Java, GUI classes, browsers
16
Option intelligent behaviour

• Using data resources on the web
• customer behaviour analysis
• competitor behaviour analysis
• environmental data
• raw material costs
• traffic predictions
• weather predictions
• Connecting to other embedded systems
• warehousing
• just-in-time delivery
• caching and sharing of large data sets
• enhance user experience

17
Complications

• Security
• Feature interaction
• Performance

18
Complication security

• Data confidentiality
• Access control and authentication
• User-friendliness of key handling
• Keeping pace with hackers and crackers
• Respecting national international regulations
• Keeping pace with trends and standardisation
  DES, RSA, PGP, AES, firewalls, etc.

19
Complication feature interaction

• many new possibilities and options
• several access levels for users
• multiple simultaneous users
• distribution

20
Complication performance

• robustness and locality of control loops
• in principle, IP does not guarantee (timely)
  delivery of packets
• critical control loops only across owned lines
• speed predictability of high-level languages
• size and costs of processor(s)
• locking and transaction management

21
Trends at the 1999 San JoseEmbedded Internet
Workshop

• future of embedded internet
• embedded web servers
• real life applications
• embedded XML/HTML
• application development
• embedded web hardware
• embedded Java
• achieving web security
• embedded web databases

22
Trend it is predicted that embedded Internet
will happen

• post PC era, smart devices
• more devices on the Internet than people by 2003
• average microprocessors in a home rises from 63
  to 250
• low cost wireless connectivity will be a driving
  enabler
• niche vertical players may be the initial
  adopters for new technology such as Java

24
Trend embedded server considered a key component

• Allegro RomPager
• 50K ROM 10K Ram for typical system
• runs on RTOS, OS-9, VxWorks, QNX
• RapidControl BackplaneTM
• kind of data-dictionary that mediates access to
  embedded data
• support for Telnet, HTTP, XML, set/get from
  remote Java
• PicoWebTM server
• 25 PCB 16K I2C EEPROM
• various IO ports
• support for CGI, HTML, JPEG

25
Platform independent

• Code
• Graphical user interface

Remote user

• Embedded system

embedded Java, GUI classes, browsers
26
Trend claiming the worlds smallest web server

• Internet Tuner(R) by iReady
• 1.5 x 1.375
• Seiko S7600 chip does TCP, IP, UDP, 50K
• PIC processor at 7.3 Mhz
• Web server in 200 bytes
• HTML page in 400 bytes

27
Trend many new companies

• Automata International Marketing,
• National Instruments,
• Lightner Engineering,
• Concur System Technologies,
• PC Soft International,
• Enikia, Intrinsyc, Object Technology, Inc., US
  Software Corp., Insignia Solutions, IP Solutions
  Corp., Norscan, iReady Corp., Microware Systems
  Corp., Certicon Corp., emWare Inc., Oracle Corp,
  Sybase, Circuit Cellar.

28
Trend following the developments of Sun,
Microsoft and Netscape

• high interest in lightweight Java versions
• interest in Jini and DCOM
• interest in SSL
• final observation the embedded systems will not
  be stand-alone, but need server support because
  of resource constraints and for software download

29
Conclusion

• Developments are already going fast but...
• When short-range wire-less connections become
  widely available, it will go really fast
• Wire will remain in use for wide-band,
  long-distance information transport
• Use standards, especially in software
• IP should go into the embedded system
