Internet Architecture

What Is the Internet?
One of the most frequently asked questions about the Internet is "Who runs it?" The truth is that no centralized management of the Internet exists. Instead, it is a collection of thousands of individual networks and organizations, each of which is run. Each network cooperates with other networks to direct Internet traffic so that information can pass among them. Together, these networks and organizations make up the world of the Internet
The Internet isn t a single network; it is a vast network of networks. No single person, group, or organization runs the Internet.
The networks communicate with one another based on certain protocols, such as the Transmission Control Protocol (TCP) and the Internet Protocol (IP). More and more networks and computers are being hooked up to the Internet every day. Tens of thousands of these networks exist, ranging from university networks to corporate local area networks to large online services such as America Online and MSN. Every time you tap into the Internet, your own computer becomes an extension of that network.
For networks and computers to cooperate in this way, however, a general agreement must take place about things such as Internet procedures and standards for protocols. These procedures and standards are laid out in requests for comment (RFCs) that are agreed on by Internet users and organizations.
A variety of groups guide the Internet s growth by helping to establish standards and by educating people on the proper way to use the Internet. Perhaps the most important is the Internet Society, a private, nonprofit group. The Internet Society supports the work of the Internet Architecture Board (IAB), which handles much of the Internet s behind-the-scenes and architectural issues. The Internet Engineering Task Force (IETF) is responsible for overseeing how the Internet s TCP/IP protocols evolve. For information about the IETF, go to www.ietf.org.
