BOLT: A UDP-Based Bulk File Transfer Protocol with Application-Aware Rate Control

Key Points

• The objective is to introduce and evaluate BOLT, a new UDP-based file transfer protocol for high-latency environments.
• Developed BOLT protocol featuring a state-machine rate controller and loss-cliff memory.
• Conducted evaluations against TCP variants and PEP-accelerated TCP at a Patagonian meteorological station.
• Analyzed performance in terms of transfer efficiency and protocol robustness.
• BOLT outperforms classic TCP and modern TCP in terms of file transfer speed over high-latency links.
• Demonstrates enhanced reliability and lower packet loss compared to conventional methods.
• Achieves better efficiency with loss-cliff memory and authenticated encryption features.
