    Endpoint devices (commonly PoE switches) are Ethernet networking equipment that includes the power-over-Ethernet transmission circuitry. Midspan devices are power injectors that stand between a non-PoE Ethernet switch (or one that cannot provide sufficient power) and the powered device, injecting power without affecting the data.

  3. Ethernet Ring Protection Switching - Wikipedia

    The principle of loop avoidance. The utilization of learning, forwarding, and Filtering Database (FDB) mechanisms defined in the Ethernet flow forwarding function (ETH_FF). Loop avoidance in an Ethernet Ring is achieved by guaranteeing that, at any time, traffic may flow on all but one of the ring links.

    Carrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". [1] [2] When they do transmit, nodes transmit their packet data in its entirety.

  6. Switching loop - Wikipedia

    en.wikipedia.org/wiki/Switching_loop

    Switching loops can cause misleading entries in a switch's media access control (MAC) database and can cause endless unicast frames to be broadcast throughout the network. A loop can make a switch receive the same broadcast frames on two different ports, and alternatingly associate the sending MAC address with the one or the other port.

    Weighted random early detection (WRED) is a queueing discipline for a network scheduler suited for congestion avoidance. [1] It is an extension to random early detection (RED) where a single queue may have several different sets of queue thresholds. Each threshold set is associated to a particular traffic class.
