Hi Stretch, Well firstly will admire you for such a great work ( packetlife.net), by which you are connecting many many network experts and sharing such a valuable knowledge base with all.. Hats off for such a great work.

I am very new to network domain and very interested in it. But my mind stops working when i get questions like what might be the architecture of internet across globe?? who owns the internet?? who gives bandwidth to the vendors from whom we get the internet connection??? You are the network expert so i thought to ask this question.. Can u please answer it with the internet architecture and cycle of connection..

Hi Naina

so happy that their is a girl here in Packetlife beside me! wish you all Luck.I'm a beginner in network & I hope to be an expert one day..nice ideas about global Internet. hope that stretch write such a blog.

The OP's question is not something quickly or easily answered. However, Wikipedia might be a good place for you to start.

http://en.wikipedia.org/wiki/Internet

The architecture of the internet is TCP/IP itself.

No one owns the internet, but many companies own some of the equipment that the Internet travels across and resides upon. Other entities have been given certain administrative power over functions of the internet. The internet itself is based upon standard which allow these separate 'pieces' to function as a larger infrastructure.

Whoever owns the particular segment of infrastructure 'owns' the bandwidth in a manner of speaking, and sell connectivity to smaller providers.

Well, you cannot write a blog article describing the Internet architecture, however I would suggest a very good book, though it is a bit old, it will give you a great deal of info about the infrastructure and how the Internet works, it is like a guide or reference.

ISP Design , the definitive guide, Sybex

It is very useful book, I advice that you read it, I hope it helps.
