Ccna exploration pdf - Google ДокументиThe Internet protocol suite is the conceptual model and set of communications protocols used in the Internet and similar computer networks. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed , and received. This functionality is organized into four abstraction layers , which classify all related protocols according to the scope of networking involved. The Internet protocol suite predates the OSI model , a more comprehensive reference framework for general networking systems. In , Robert E. Kahn joined the DARPA Information Processing Technology Office , where he worked on both satellite packet networks and ground-based radio packet networks, and recognized the value of being able to communicate across both. By the summer of , Kahn and Cerf had worked out a fundamental reformulation, in which the differences between local network protocols were hidden by using a common internetwork protocol , and, instead of the network being responsible for reliability, as in the existing ARPANET protocols, this function was delegated to the hosts.
