Go-Back-N ARQ — Visual Simulator

Go-Back-N ARQ is a sliding window protocol that improves efficiency by letting the sender transmit multiple frames before needing ACKs.

🔹 How It Works

• Sender can send up to N unacknowledged frames.
• Receiver sends cumulative ACKs.
• Timeout triggers retransmission from the base frame.

This simulator lets you visualize how Go-Back-N ARQ behaves under different network conditions.
