TCP/IP
Internet Protocol version 4 ( IPv4 ) is the fourth revision in the development of the Internet Protocol (IP) and the first version of the protocol to be widely deployed. Together with IPv6 , it is at the core of standards-based internetworking methods of the Internet . As of 2012 [update] IPv4 is still the most widely deployed Internet Layer protocol. IPv4 is described in IETF publication RFC 791 (September 1981), replacing an earlier definition ( RFC 760 , January 1980). IPv4 is a connectionless protocol for use on packet-switched Link Layer networks (e.g., Ethernet ).

MITRE's role is often to look ahead in areas of science and technology and figure out how new ideas may solve our sponsors' problems—both today's and tomorrow's. Our Emerging and Disruptive Technologies Office nurtures programs in technology areas not traditionally part of MITRE's work, in order to apply that increased understanding to the practical challenges of our sponsors. Some of these areas of study may result from new intersections of existing technology, such as biology, information technology, and systems engineering.

February 14, 2012 The Cisco ® Visual Networking Index (VNI) Global Mobile Data Traffic Forecast Update is part of the comprehensive Cisco VNI Forecast, an ongoing initiative to track and forecast the impact of visual networking applications on global networks. This paper presents some of Cisco's major global mobile data traffic projections and growth trends. Global mobile data traffic grew 2.3-fold in 2011, more than doubling for the fourth year in a row . The 2011 mobile data traffic growth rate was higher than anticipated.

Host (network) - Wikipedia, the free encyclopedia
A network host is a computer connected to a computer network . A network host may offer information resources, services, and applications to users or other nodes on the network. A network host is a network node that is assigned a network layer host address . Computers participating in networks that use the Internet Protocol Suite may also be called IP hosts.IPv6 ( Internet Protocol version 6 ) is a version of the Internet Protocol (IP) intended to succeed IPv4 , which is the protocol currently used to direct almost all Internet traffic. [ 1 ] The Internet operates by transferring data between hosts in packets that are routed across networks as specified by routing protocols . These packets require an addressing scheme, such as IPv4 or IPv6, to specify their source and destination addresses. Each host, computer or other device on the Internet requires an IP address in order to communicate. The growth of the Internet has created a need for more addresses than are possible with IPv4. The last top level ( /8 ) block of free IPv4 addresses was assigned in February 2011 by IANA to the 5 RIRs , although many free addresses still remain in most assigned blocks and RIRs will continue with standard policy until it is at its last /8 .

The Internet protocol suite is the set of communications protocols used for the Internet and other similar networks. It is commonly known as TCP/IP , because of its most important protocols: Transmission Control Protocol (TCP) and Internet Protocol (IP), which were the first networking protocols defined in this standard. Modern IP networking represents a synthesis of several developments that began to evolve in the 1960s and 1970s, namely the precursors of the Internet and local area networks , which emerged during the 1980s, together with the advent of the World Wide Web in the early 1990s. The application layer contains all protocols defined specifically for the functioning of the vast array of data communications services.

Dynamic Host Configuration Protocol - Wikipedia, the free encyclopedia
A DHCP Server settings tab The Dynamic Host Configuration Protocol ( DHCP ) is a network configuration protocol for hosts on Internet Protocol (IP) networks. Computers that are connected to IP networks must be configured before they can communicate with other hosts. The most essential information needed is an IP address , and a default route and routing prefix.
Network switch - Wikipedia, the free encyclopedia
A network switch or switching hub is a computer networking device that connects network segments or network devices . The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model . Switches that additionally process data at the network layer (layer 3) and above are often referred to as layer-3 switches or multilayer switches . A switch is a telecommunication device which receives a message from any device connected to it and then transmits the message only to that device for which the message was meant. This makes the switch a more intelligent device than a hub (which receives a message and then transmits it to all the other devices on its network.) The network switch plays an integral part in most modern Ethernet local area networks (LANs).Software Downloads
