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.
Common causes of such issues include high latency between server and client, packet loss, network congestion, and external factors independent to network quality such as frame rendering time or inconsistent frame rates. [1] [2] Netcodes may be designed to uphold a synchronous and seamless experience between users despite these networking ...
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

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.
The receiver of the packet echoes the congestion indication to the sender, which reduces its transmission rate as if it detected a dropped packet. Rather than responding properly or ignoring the bits, some outdated or faulty network equipment has historically dropped or mangled packets that have ECN bits set.
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.):
In the field of computer networking, TCP pacing is the denomination of a set of techniques to make the pattern of packet transmission generated by the Transmission Control Protocol less bursty. Where there could be insufficient buffers in switches and routers, TCP Pacing is intended to avoid packet loss due to exhaustion of buffer memory in ...
