Vortex Protocol

Introduction

Vortex protocol is a high-performance peer-to-peer (P2P) file transfer protocol implementation in Rust, designed as part of the Dragonfly project. It utilizes the TLV (Tag-Length-Value) format for efficient and flexible data transmission, making it ideal for large-scale file distribution scenarios.

Features

• Efficient TLV Protocol: Optimized for fast serialization and deserialization of data packets.
• Large File Support: Handles piece sizes up to 1 GiB and value fields up to 4 GiB.
• Memory Safety: Built in Rust with zero-cost abstractions and memory safety guarantees.
• High Performance: Designed for high-throughput file transfer scenarios.
• Extensible Design: Reserved tags for future protocol extensions like compression and encryption.

Benchmarking

Vortex protocol includes comprehensive benchmarks for packet creation, serialization, and deserialization:

# Run all benchmarks
cargo bench

# Run specific benchmark group
cargo bench "Vortex Packet Creation"

The benchmarks cover various packet sizes:

• Small packets (32 bytes)
• Medium packets (1 KB)
• Large packets (1 MB)
• Extra large packets (16 MB)
