In telecommunications, packet switching is a method of grouping data into short messages in fixed format, i.e. packets, that are transmitted over a digital network. Packets are made of a header and a payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an ...
PacketExchange was a British multinational network services provider based in London.Founded in 2002 by Jason Velody and Kieron O'Brien, both supported by Nigel Titley, Giles Heron, and Katie Snowball as the founding team, its network connected 45 points of presence across Europe, Asia, and the United States over a private backbone consisting primarily of multiple 10 Gigabit Ethernet links ...

The film was co-written and directed by Andrei Tarkovsky, and stars Donatas Banionis and Natalya Bondarchuk. The electronic music score was performed by Eduard ...
At the transmitter, the calculation is performed before the packet is sent. When received at the destination, the checksum is recalculated, and compared with the one in the packet. If discrepancies are found, the packet may be corrected or discarded. Any packet loss due to these discards is dealt with by the network protocol.
A broadcast forwarding pattern, typical of bridged Ethernet. The simplest forwarding model— unicasting —involves a packet being relayed from link to link along a chain leading from the packet's source to its destination. However, other forwarding strategies are commonly used. Broadcasting requires a packet to be duplicated and ...
IPX is a network-layer protocol (layer 3 of the OSI model), while SPX is a transport-layer protocol (layer 4 of the OSI model). The SPX layer sits on top of the IPX layer and provides connection-oriented services between two nodes on the network. SPX is used primarily by client–server applications. IPX and SPX both provide connection services ...
Sequenced Packet Exchange. Sequenced Packet Exchange (SPX) is a protocol in the IPX/SPX protocol stack that corresponds to a connection-oriented transport layer protocol in the OSI model. Being reliable and connection-oriented, it is analogous to the Transmission Control Protocol (TCP) of TCP/IP, but it is a datagram protocol, rather than a ...
Going Vertical, also known as Three Seconds (Russian: Движение вверх, romanized: Dvizhenie vverkh) is a 2017 Russian sports drama film directed by Anton Megerdichev about the controversial victory of the Soviet national basketball team over the 1972 U.S. Olympic team, ending their 63-game winning streak, at the Munich Summer Olympic's men's basketball tournament.
