Automatic Repeat Request vs UDP

Developers should learn ARQ when working on network protocols, distributed systems, or any application requiring reliable data transfer, such as file transfers, streaming services, or IoT communications meets developers should use udp when building applications that require minimal latency and can tolerate some data loss, such as live video/audio streaming, voip, online multiplayer games, or iot sensor data transmission. Here's our take.

Automatic Repeat Request

Nice Pick

Developers should learn ARQ when working on network protocols, distributed systems, or any application requiring reliable data transfer, such as file transfers, streaming services, or IoT communications

Pros

• It is essential for implementing error control and ensuring data consistency in scenarios where packet loss or corruption is common, like wireless networks or internet-based applications
• Related to: tcp, error-detection

Cons

• Specific tradeoffs depend on your use case

UDP

Developers should use UDP when building applications that require minimal latency and can tolerate some data loss, such as live video/audio streaming, VoIP, online multiplayer games, or IoT sensor data transmission

Pros

• It is also essential for implementing network protocols like DNS and DHCP, where quick, lightweight communication is more important than perfect reliability
• Related to: tcp, networking

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Automatic Repeat Request is a concept while UDP is a protocol. We picked Automatic Repeat Request based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Automatic Repeat Request wins

Based on overall popularity. Automatic Repeat Request is more widely used, but UDP excels in its own space.
