LZ77 maintains a "sliding window" during compression. This is somewhat analogous to TCP's sliding window used for flow control. PureView seamless sliding window (2015). The number of scans is the length of the sliding window. This is known as a sliding window process. One solution to this problem is the use of a sliding window. The size of the actual sliding window used is the sum of these two windows. Several papers also consider the "sliding window" model. The most general case of the sliding window protocol is Selective Repeat ARQ. TCP uses a sliding window flow control protocol. The pseudocode is a reproduction of the LZ77 compression algorithm sliding window. Prior to 1984, the hardtop included sliding window glass as an option. Both fixed and sliding window panels were present, along with a transparent sliding roof. The sliding window method ensures that traffic congestion on the network is avoided. A sliding window protocol is a feature of packet-based data transmission protocols.
