Bufferbloat is the undesirable latency that comes from a router or other network equipment buffering too many data packets.Bufferbloat can also cause packet delay variation (also known as jitter), as well as reduce the overall network throughput.
In computer science, a data buffer (or just buffer) is a region of memory used to store data temporarily while it is being moved from one place to another. Typically, the data is stored in a buffer as it is retrieved from an input device (such as a microphone) or just before it is sent to an output device (such as speakers); however, a buffer may be used when data is moved between processes ...
The ideal buffer is sized so it can handle a sudden burst of communication and match the speed of that burst to the speed of the slower network. Ideally, the shock-absorbing situation is characterized by a temporary delay for packets in the buffer during the transmission burst, after which the delay rapidly disappears and the network reaches a ...
Packets are normally forwarded by intermediate network nodes asynchronously using first-in, first-out buffering, but may be forwarded according to some scheduling discipline for fair queuing, traffic shaping, or for differentiated or guaranteed quality of service, such as weighted fair queuing or leaky bucket. Packet-based communication may be ...
Just as in the case of a regular buffer, it is a storage medium that enables compensation for a difference in time of occurrence of events. More specifically, an optical buffer serves to store data that was transmitted optically (i.e., in the form of light), without converting it to the electrical domain. [1]
A more likely scenario is network congestion within a switch. For example, a flow can come into a switch on a higher speed link than the one it goes out, or several flows can come in over two or more links that total more than an output link's bandwidth. These will eventually exhaust any amount of buffering in the switch.

Quality of service (QoS) is the description or measurement of the overall performance of a service, such as a telephony or computer network, or a cloud computing service, particularly the performance seen by the users of the network.
