Message Resends

Definition ∞ Message resends refer to the retransmission of data packets or messages across a network when the initial transmission is not acknowledged or is deemed lost. This mechanism is crucial for ensuring reliable communication in distributed systems, compensating for network unreliability or congestion. While necessary for data integrity, excessive message resends can increase network traffic and latency. They are a common occurrence in asynchronous communication.
Context ∞ In decentralized network architectures, managing message resends efficiently is important for maintaining protocol performance and data consistency. High rates of message resends can indicate network stress or underlying issues within the communication layer, potentially impacting transaction finality or block propagation. Developers continuously work to optimize network protocols to minimize unnecessary resends while guaranteeing data delivery.
