Selective Retransmission

Selective retransmission is a strategy where only the specific packets identified as missing are requested for resending, rather than retransmitting entire blocks of data. This is a key technique for maintaining high throughput and low latency in systems where data integrity is important but speed is paramount.

By minimizing the amount of data that needs to be resent, the system recovers from errors much faster than with standard protocols. This is particularly useful in crypto derivative trading, where a lost packet might contain a crucial price update or order confirmation.

It allows for a more granular and efficient approach to handling transmission errors in real-time.
