  2. Circuit switching - Wikipedia

    en.wikipedia.org/wiki/Circuit_switching

    In circuit switching, the bit delay is constant during a connection (as opposed to packet switching, where packet queues may cause varying and potentially indefinitely long packet transfer delays). No circuit can be degraded by competing users because it is protected from use by other callers until the circuit is released and a new connection ...

  3. Message switching - Wikipedia

    en.wikipedia.org/wiki/Message_switching

    In telecommunications, message switching involves messages routed in their entirety, one hop at a time. It evolved from circuit switching and was the precursor of packet switching. [1] An example of message switching is email in which the message is sent through different intermediate servers to reach the mail server for storing.

  4. Switched communication network - Wikipedia

    en.wikipedia.org/wiki/Switched_communication_network

    In computer networking and telecommunications, a switched communication network is a communication network which uses switching for connection of two non-adjacent nodes. Switched communication networks are divided into circuit switched networks, message switched networks, and packet switched networks.

  5. Asynchronous Transfer Mode - Wikipedia

    en.wikipedia.org/wiki/Asynchronous_Transfer_Mode

    [2] [3] ATM provides functionality that uses features of circuit switching and packet switching networks by using asynchronous time-division multiplexing. [ 4 ] [ 5 ] ATM was seen in the 1990s as a competitor to Ethernet and networks carrying IP traffic as, unlike Ethernet, it was faster and designed with quality-of-service in mind, but it fell ...

  6. Protocol Wars - Wikipedia

    en.wikipedia.org/wiki/Protocol_Wars

    Packet switching vs circuit switching [ edit ] Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users and, later, the possibility of achieving this over wide area networks .

  7. Connection-oriented communication - Wikipedia

    en.wikipedia.org/wiki/Connection-oriented...

    Packet switched communication may also be connection-oriented, which is called virtual circuit mode communication. Due to the packet switching, the communication may suffer from variable bit rate and delay, due to varying traffic load and packet queue lengths. Connection-oriented communication does not necessarily imply reliability.

  8. Routing - Wikipedia

    en.wikipedia.org/wiki/Routing

    Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision making that directs network packets from their source toward their destination through ...

  9. Traffic flow (computer networking) - Wikipedia

    en.wikipedia.org/wiki/Traffic_flow_(computer...

    In the TCP case, a flow may be a virtual circuit, also known as a virtual connection or a byte stream. [4] In packet switches, the flow may be identified by IEEE 802.1Q Virtual LAN tagging in Ethernet networks, or by a label-switched path in MPLS tag switching. Packet flow can be represented as a path in a network
