  2. 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 ...

  3. Packet switching - Wikipedia

    en.wikipedia.org/wiki/Packet_switching

    CompuServe developed its own packet switching network, implemented on DEC PDP-11 minicomputers acting as network nodes that were installed throughout the US (and later, in other countries) and interconnected. Over time, the CompuServe network evolved into a complicated multi-tiered network incorporating ATM, Frame Relay, IP and X.25 technologies.

  4. NAT traversal - Wikipedia

    en.wikipedia.org/wiki/NAT_traversal

    Network address translation typically uses private IP addresses on private networks with a single public IP address for the router facing the Internet.The network address translator changes the source address in network protocols for outgoing requests from that of an internal device to its external address, so that internal devices can communicate with hosts on the external network, while ...

  5. OSI model - Wikipedia

    en.wikipedia.org/wiki/OSI_model

    A network is a medium to which many nodes can be connected, on which every node has an address and which permits nodes connected to it to transfer messages to other nodes connected to it by merely providing the content of a message and the address of the destination node and letting the network find the way to deliver the message to the ...

  6. Network address translation - Wikipedia

    en.wikipedia.org/wiki/Network_address_translation

    Network address mapping. Most network address translators map multiple private hosts to one publicly exposed IP address. Here is a typical configuration: A local network uses one of the designated private IP address subnets (RFC 1918 [4]). The network has a router having both a private and a public address.

  7. 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.

  8. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_packet

    In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network. A packet consists of control information and user data; [ 1 ] the latter is also known as the payload .

  9. Source routing - Wikipedia

    en.wikipedia.org/wiki/Source_routing

    In computer networking, source routing, also called path addressing, allows a sender of a data packet to partially or completely specify the route the packet takes through the network. [1] In contrast, in conventional routing , routers in the network determine the path incrementally based on the packet's destination.
