Thus, you get a preload of the contentthat avoids skipping orinterruptions in the viewing if the flow of information is cut briefly, due to interruptions in the connectionor overload of the bandwidth.
In addition to that, lightweight file transfer protocols are used forstreaming.designed to avoid such interruptions.
For example, the UDP protocol makes the delivery of datapackets from the server to the client that demands the file, is done with a higher speed and with much morereliability than if a TCP or HTTP protocol were used.
The latter, at the moment they detect a transmission error, continue trying to transmit the lost data packets until they obtain confirmation that the informationhas arrived in its entirety.
The UDP protocol achieves greater efficiency by using a transfer mode that favorscontinuous flow, sending data without taking interruptions into account, since if a packet of information is lost in a streaming reproduction, these losses are practically imperceptible.The streaming system is used by popular content distribution platforms such as Netflix or YouTube.
