[![Slicing Speed](https://img.shields.io/badge/Slicing-0.1ms-orange.svg)](#benchmarks)

An open-core, high-throughput transport protocol designed to stream active Large Language Model (LLM) Key-Value (KV) Cache states across datacenters. 

By eliminating prompt re-computation during session handoffs, this protocol cuts Time-To-First-Token (TTFT) latency down to **81.73 ms** and saves up to **95%** in GPU VRAM compute overhead.

## Benchmarks

| Metric | Standard Re-computation | Protocol Engine | Delta |
| :--- | :--- | :--- | :--- |
| **Max Migration Latency** | ~$450.00\text{ ms} - 1200.00\text{ ms}$ | **$81.73\text{ ms}$** | **$5.5\times$ Faster** |
| **Memory Slicing Speed** | N/A (Full Compute) | **$0.10\text{ ms}$** | **Ultra-Low Overhead** |
| **Target Ingestion Time** | N/A | **$1.63\text{ ms}$** | **Deterministic** |
| **VRAM Compute Load** | $100\%$ GPU Compute Load | **$< 5\%$ I/O Load** | **$95\%$ Compute Savings** |

## Quickstart (Run Benchmark)

Run the local benchmark simulator to test memory buffer slicing on your current hardware:

``` bash
git clone [https://github.com/YOUR_USERNAME/YOUR_REPO_NAME.git](https://github.com/YOUR_USERNAME/YOUR_REPO_NAME.git)
cd YOUR_REPO_NAME
python3 benchmark/run_benchmark.py --buffer-size 128 --iterations 1000
```
