  2. Packet loss - Wikipedia

    en.wikipedia.org/wiki/Packet_loss

    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. The Transmission Control Protocol (TCP) detects packet loss and performs retransmissions to ensure reliable messaging.

    en.wikipedia.org/wiki/Ping_(networking_utility)

    ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. It is available in a wide range of operating systems – including most embedded network administration software.

  5. 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

  6. Bufferbloat - Wikipedia

    en.wikipedia.org/wiki/Bufferbloat

    Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput. When a router or switch is configured to use excessively large buffers, even very high-speed networks can become practically unusable for many interactive applications like voice over IP (VoIP), audio streaming , online ...

  7. 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:

  8. Network packet - Wikipedia

    en.wikipedia.org/wiki/Network_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. In some cases, modifications of the network packet may be necessary while routing, in which cases checksums are recalculated. Hop limit Under fault conditions, packets can end up traversing a closed ...

  9. IP fragmentation - Wikipedia

    en.wikipedia.org/wiki/IP_fragmentation

    An example of the fragmentation of a protocol data unit in a given layer into smaller fragments. IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size.
