Which of the following functions are performed by the OSI Transport layer
Upon acknowledgment of the first segment (the receiver sends an acknowledgment requesting the next segment), the window size doubles. If the first two segments are successfully received, the next window contains four segments. There is an exponential increase in window size until the receiver acknowledges the successful receipt of all segments within a certain period of time (called the round-trip time or RTT) or until a configured maximum window size has been reached.Using buffering, a device (for example, a router) stores segments in a piece of memory (sometimes called a buffer or a queue) if the bandwidth is not available to transmit those segments. There is a finite capacity for a queue, however, and it can overflow (that is, drop segments) in the event of prolonged network congestion.
