Some protocols allow for error correction by requesting retransmission. Technical means can reduce errors with error correcting codes, retransmission, checksums, or diversity scheme. As the number of retransmission attempts increases, the number of possibilities for delay increases exponentially. It was improved towards the TCP protocol by using selective and immediate (NAK-based) retransmission. But for distribution of critical data, a mechanism is required for requesting retransmission. This retransmission causes the overall throughput of the connection to drop. Three-way handshake (active open), retransmission, and error-detection adds to reliability but lengthens latency. Error recovery is by retransmission of the corrupted frame. However, early TCP implementations had poor retransmission behavior. The dispute centered around KXAN's failure to grant retransmission consent to Suddenlink. ABC still uses the Prospect facility as a network retransmission center for its programming. A NAK will prompt retransmission of the data. The two companies could not reach an agreement over retransmission fees. This avoids retransmission of highly time-critical data. Is it a new one or is it a retransmission?
