Reliable Communication Layers
Understand how to build reliable communication layers in distributed systems by exploring mechanisms like acknowledgments, timeouts, retries, and sequence counters. This lesson helps you grasp how to detect lost messages, handle duplicates, and ensure messages are received exactly once to maintain data integrity over unreliable networks.

To build a reliable communication layer, we need some new mechanisms and techniques to handle packet loss. Let us consider a simple example in which a client is sending a message to a server over an unreliable connection. The first question we must answer: how does the sender know that the receiver has actually received the message?
Acknowledgment (ack)
