  2. Packet switching - Wikipedia

    en.wikipedia.org/wiki/Packet_switching

    Donald Davies' work on data communications and computer network design became well known in the United States, Europe and Japan and was the "cornerstone" that inspired numerous packet switching networks in the decade following.

  3. Packet processing - Wikipedia

    en.wikipedia.org/wiki/Packet_Processing

    Within any network enabled device (e.g. router, switch, network element or terminal such as a computer or smartphone) it is the packet processing subsystem that manages the traversal of the multi-layered network or protocol stack from the lower, physical and network layers all the way through to the application layer.

  4. Data link layer - Wikipedia

    en.wikipedia.org/wiki/Data_link_layer

    Inter-network routing and global addressing are higher-layer functions, allowing data-link protocols to focus on local delivery, addressing, and media arbitration. In this way, the data link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium, without concern for their ...

  5. Network layer - Wikipedia

    en.wikipedia.org/wiki/Network_layer

    The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI (Open Systems Interconnection) network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.

  6. Internet protocol suite - Wikipedia

    en.wikipedia.org/wiki/Internet_protocol_suite

    The Internet Protocol is the principal component of the internet layer, and it defines two addressing systems to identify network hosts and to locate them on the network. The original address system of the ARPANET and its successor, the Internet, is Internet Protocol version 4 (IPv4).

  7. Network architecture - Wikipedia

    en.wikipedia.org/wiki/Network_architecture

    Network architecture is the design of a computer network.It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used.

  8. Network planning and design - Wikipedia

    en.wikipedia.org/wiki/Network_planning_and_design

    Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. [1] The process can be tailored according to each new network or service. [2]

  9. Medium access control - Wikipedia

    en.wikipedia.org/wiki/Medium_access_control

    The channel access control mechanism relies on a physical layer multiplex scheme. The most widespread multiple access method is the contention-based CSMA/CD used in Ethernet networks. This mechanism is only utilized within a network collision domain, for example, an Ethernet bus network or a hub-based star topology network.
