Network Optimizations for Cloud Syncing

I'm looking to improve the performance of my cloud storage sync client across varied network conditions. Specifically, I need advice on:

• Adaptive throttling mechanisms
• Efficient handling of high latency links
• Utilizing UDP‑based transfer protocols where possible

Any real‑world implementations or recommended libraries?

For adaptive throttling, I've had success with a token bucket algorithm that dynamically adjusts based on measured RTT and packet loss. You can implement it yourself or use Google's TrafficManager which already handles the feedback loop.

When dealing with high latency, consider using a chunked transfer approach combined with forward error correction (FEC). This reduces retransmission overhead. The libxudp library provides a solid UDP abstraction with built‑in congestion control.
