VSAT (VOLUMETRIC SOCKET ARTILLERY) is an advanced multi-layer network traffic generation framework designed for:
- Network stress testing
- Infrastructure benchmarking
- Protocol analysis
- Defensive security research
- High concurrency traffic simulation
- HTTP/2 multiplexing analysis
- TLS JA3 fingerprint experimentation
- Raw socket packet crafting research
The framework combines Layer 3, Layer 4, and Layer 7 traffic engines into a unified multiprocessing architecture capable of generating high-throughput traffic across multiple network protocols.
