Internetworking with TCP/IP- P75: TCP/IP has accommodated change well. The basic technology has survived nearly two decades of exponential growth and the associated increases in traffic. The protocols have worked over new high-speed network technologies, and the design has handled applications that could not be imagined in the original design. Of course, the entire protocol suite has not remained static. New protocols have been deployed, and new techniques have been developed to adapt existing protocols to new network technologies | TCP IP Internet Terms In Alphabetical Order 699 mobile IP A technology developed by the IETF to permit a computer to travel to a new site while retaining its original IP address. The computer contacts a server to obtain a second temporary address and then arranges for all datagrams to be forwarded to it. Mosaic An early Web browser program. MOSPF Multicast Open Shortest Path First Multicast Extensions to the OSPF routing protocol. MPLS Multi-Protocol Label Switching A technology that uses high speed switching hardware to carry IP datagrams. MPLS is descended from IP switching and label switching. mrouted Multicast ROUTE Daemon A program used with a protocol stack that supports IP multicast to establish multicast routing. MSL Maximum Segment Lifetime The longest time a datagram can survive in the Internet. Protocols use the MSL to guarantee a bound on the time duplicate packets can survive. MSS Maximum Segment Size A term used with TCP. The MSS is the largest amount of data that can be transmitted in one segment. Sender and receiver negotiate maximum segment size at connection startup. MTU Maximum Transfer Unit or Maximum Transmission Unit The largest amount of data that can be transferred across a given physical network. The MTU is determined by the network hardware. multi-homed host A host using TCP IP that has connections to two or more physical networks. multicast A technique that allows copies of a single packet to be passed to a selected subset of all possible destinations. Some hardware . Ethernet supports multicast by allowing a network interface to belong to one or more multicast groups. IP supports an internet multicast facility. multiplex To combine data from several sources into a single stream in such a way that it can be separated again later. Multiplexing occurs at many levels. See demultiplex. multiplicative decrease A technique used by TCP to reduce transmission when congestion occurs. TCP decreases the size of the effective window by half each .
