  2. Packet loss - Wikipedia

    en.wikipedia.org/wiki/Packet_loss

    Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, [1] [2] or network congestion. [3]: 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.

  3. Packet loss concealment - Wikipedia

    en.wikipedia.org/wiki/Packet_loss_concealment

    Packet loss concealment (PLC) is a technique to mask the effects of packet loss in voice over IP (VoIP) communications. When the voice signal is sent as VoIP packets on an IP network, the packets may (and likely will) travel different routes. A packet therefore might arrive very late, might be corrupted, or simply might not arrive at all.

  4. Network congestion - Wikipedia

    en.wikipedia.org/wiki/Network_congestion

    Network congestion in data networking and queueing theory is the reduced quality of service that occurs when a network node or link is carrying more data than it can handle. . Typical effects include queueing delay, packet loss or the blocking of new connectio

  5. Error concealment - Wikipedia

    en.wikipedia.org/wiki/Error_concealment

    When a packet is lost, rather than losing an entire set of data, small portions of several sets will be gone. At the receiving end, the message is then deinterleaved to reveal the original message with minimal loss. Transmission without interleaving:

  6. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_packet

    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.

  7. Quality of service - Wikipedia

    en.wikipedia.org/wiki/Quality_of_service

    Packet loss The network may fail to deliver ( drop ) some packets due to network congestion. The receiving application may ask for this information to be retransmitted, possibly resulting in congestive collapse or unacceptable delays in the overall transmission.

  8. TCP congestion control - Wikipedia

    en.wikipedia.org/wiki/TCP_congestion_control

    While most CCAs are loss-based, in that they rely on packet loss to detect congestion and lower rates of transmission, BBR, like TCP Vegas, is model-based. The algorithm uses the maximum bandwidth and round-trip time at which the network delivered the most recent flight of outbound data packets to build a model of the network.

  9. TCP tuning - Wikipedia

    en.wikipedia.org/wiki/TCP_tuning

    When packet loss occurs in the network, an additional limit is imposed on the connection. [2] In the case of light to moderate packet loss when the TCP rate is limited by the congestion avoidance algorithm, the limit can be calculated according to the formula (Mathis, et al.):
