Who invented the tcp ip standard




















The Internet is a packet-switched network, in which information is broken down into small packets, sent individually over many different routes at the same time, and then reassembled at the receiving end.

TCP is the component that collects and reassembles the packets of data, while IP is responsible for making sure the packets are sent to the right destination. It is the set of communications protocols used for the Internet and other similar networks. It is named from two of the most important protocols in it: the Transmission Control Protocol TCP and the Internet Protocol IP , which were the first two networking protocols defined in this standard. The design of the network included the recognition that it should provide only the functions of efficiently transmitting and routing traffic between end nodes and that all other intelligence should be located at the edge of the network, in the end nodes.

Using a simple design, it became possible to connect almost any network to the ARPANet, irrespective of their local characteristics. A computer or device called a router a name changed from gateway to avoid confusion with other types of gateways is provided with an interface to each network, and forwards packets back and forth between them. Requirements for routers are defined in RFC The Internet Protocol Suite, like many protocol suites, may be viewed as a set of layers.

Then just click OK. That's usually how one builds a structure, after all. The history of IP, however, is a bit more complex. The functions it performs were defined at the birth of the protocol, but IP itself didn't exist for the first few years that the protocol suite was being defined. This standard, which was a revision of the similar RFC of the previous year, defined the core functionality and characteristics of the IP that has been in widespread use for the last two decades.

Interestingly, however, it is not version 1 of IP but version 4! This would of course imply that there were earlier versions of the protocol at one point. Interestingly, however, there really weren't.

Key Concept: Version 4 of the Internet Protocol is in fact the first version that was widely deployed and is the one in current widespread use. This version number is carried in the appropriate field of all IP datagrams, as described in the topic discussing the IP datagram format. Given that it was originally designed for an internetwork a tiny fraction of the size of our current Internet, IPv4 has proven itself remarkably capable.

Various additions and changes have been made over time to how IP is used, especially with respect to addressing, but the core protocol is basically what it was in the early s. There's good reason for this: changing something as fundamental as IP requires a great deal of development effort and also introduces complexities during transition.

Despite how well IPv4 has served us, it was recognized that for various reasons a new version of IP would eventually be required. Due to the difficulties associated with making such an important change, development of this new version of IP has actually been underway since the mids. A natural question at this point of course is: what happened to version 5 of IP?

The answer is: it doesn't exist. While this may seem confusing, version 5 was in fact intentionally skipped to avoid confusion, or at least to rectify it.
