The single chip computer on the site runs the iPic web-server, the world’s tiniest implementation of a TCP/IP stack and a HTTP web-server. The TCP/IP stack and the webserver uses around 30 bytes of RAM. The code is written in C ideas that Miniweb uses: iPIC – A Match Head Sized Web Server. Additionally, tiny, inexpensive Web servers make the vision of a totally Shri said the iPic server has been online since the middle of July.

Most eerily, once this is all set up, you do not need the computer to control the appliances — they can communicate with each other through the power wiring and co-ordinate each other’s activities.

At the office many industrial computers and devices are equipped with their own remote management facilities. Searching our resource database to find your matches He expects it to “eventually” be built into silicon, “and not remain just a software application”.

Some of the products that appear on this site are from companies from which QuinStreet receives compensation. Shrikumar is glad that after nearly six months of “going insane with this crazy hobby,” his brain is finally getting some rest. His sister is attending a college in Bombay.

The stateless Miniweb keeps only minimal state information. Home Code Science Talks Contact.

Fingernail-sized web server could spread net wider – ABC Green @ Work

This connection will hang until the application in the other end sends data. The stateless variant is a bit smaller and uses less RAM, but does not provide the same functionality as the statefull variant. Each of the appliances we use in offices and homes has its own array of buttons and indicators, he points out.


His discovery could become a part of everyday life in homes across the world, he asserts. At that rate it should be able to serve about hits per hour. Toggle navigation Adam Dunkels. Thanks to a graduate student at an American university, the day when you may control every electrical device in your life with a web browser ipkc a lot closer.

Seriously, he says his father, S H Subrahmanian, a physics professor and his mother, Kokilamani who taught biology, had instilled in him from his childhood the ideals of tenacity.

iPic Web Server Aims to Make Toaster-Net a Reality

It is connected to the Internet through a serial port. These devices and appliances can all then be controlled from your web-browser. The previous record for a small web server was held by Stanford University, who developed a server the size of a matchbox earlier this year. Hariharasubrahmanian Shrikumar has made a web server out of a single microchip the size of a fingernail.

There are two variants of Miniweb, a stateless variant and a statefull variant. Instead lpic keeping connection state, the stateless Miniweb uses the acknowledgement numbers of the incomming ACKs to decide which TCP segment to send. The checksum is computed when each byte is received and if the checksum is found to be incorrect when the entire packet has been received, the contents of the packet is not used for further processing.

The number of lines of code are approximate.

This compensation may impact how and where products appear on this site including, for example, the order in which they appear. He says because the machine is a Web-server, it does not need a keyboard or display, but is operated wbe another computer using a Web connection. What is your job function?


Miniweb – TCP/IP stack and web server in 30 bytes

Download the code and do: This means that all the electrical devices in your house would be able to communicate with each other, and could be controlled from a home computer. He recalls John Romkey, a well-known computer-networking researcher, predicting in that one day every toaster would be on the Net.

When sending the packets, only a few fields are updated and the checksums adjusted. The inventor of the smallest Web-server in the world, year-old Shrikumar, a Ph D candidate at a school here, is thinking of the great use the Web-server would have in offices and home.

Thanks for your registration, follow us on our social networks to keep up-to-date. His Web-server has been shrunk about two orders of magnitude, serevr almost times smaller in physical size, and 1, times smaller in software size, he says.

In terms of technology, the achievement is not only in connecting a small computer on the Web, but also in the size of the network software that is running on the chip, he explains. He has reportedly has beaten many contenders including researchers at several big universities and corporations. Coupled with a small chip for memory and a battery, the whole package could be as small as a pack of gum and be used to a variety of household, industry and mobile applications.

The iPic web server could be used to connect all kinds of electrical devices to the internet. The eventual applications of his discovery could be “phenomenal,” he says.
