## The Problem

Your ISP's routing is suboptimal:
- **Congested peering points** → packet loss
- **Cost-optimized routes** → unnecessary latency (+50-200ms)
- **No QoS guarantees** → inconsistent performance

## The Solution

```
❌ Direct (Your ISP): You → Congested ISP routes → Destination (120ms, 2% loss)
✅ Via Oxidize: You → QUIC tunnel → Premium edge → Destination (80ms, 0% loss)
```

## Architecture

```
┌─────────────────┐ ┌─────────────────┐
│ Your Device │ QUIC │ Relay Server │
│ oxidize-client │ ──────► │ oxidize-server │ ──────► Internet
└─────────────────┘ └─────────────────┘
↑ ↑
TCP + UDP TCP + UDP
captured forwarded
```

- **Full traffic tunneling** — ALL TCP and UDP traffic flows through the relay
- **Dedicated infrastructure** — no peer-to-peer, no bandwidth sharing with strangers
- **Smart routing** — gaming tunneled, streaming bypassed for zero latency

### 📱 OxTunnel Protocol (Unified Cross-Platform)
Custom high-performance tunnel protocol replacing WireGuard with **unified architecture** for all platforms:

```
┌─────────────────────────────────────────────────────────────────────┐
│ OxTunnel Protocol (TCP + UDP) │
├─────────────────────────────────────────────────────────────────────┤
│ Linux: App → NFQUEUE → OxTunnel → QUIC Datagrams → Server │
│ macOS: App → PF/Utun → OxTunnel → QUIC Datagrams → Server │
│ Windows: App → WinDivert → OxTunnel → QUIC Datagrams → Server │
│ Android: App → VpnService → OxTunnel → QUIC Datagrams → Server │
│ iOS: App → NEPacketTunnel → OxTunnel → QUIC Datagrams → Server│
└─────────────────────────────────────────────────────────────────────┘
All platforms: TCP + UDP tunneled, UDP fallback when QUIC blocked
```

- **Same protocol everywhere** - All platforms use identical OxTunnel encapsulation
- **Platform-specific capture** - NFQUEUE (Linux), PF (macOS), WinDivert (Windows), VpnService (Android)
- **QUIC primary transport** - Encrypted, multiplexed, 0-RTT for all platforms

- **64 packets/batch** - Reduces syscalls by 64x
- **Zero-copy buffer pools** - 128 pre-allocated buffers, no heap allocation per packet

| Feature | WireGuard | OxTunnel |
|---------|-----------|----------|
| Header size | 32+ bytes | **4 bytes avg** (V2) |
| Encryption | Double (WG + TLS) | Single (QUIC TLS 1.3) |
| Handshake | Multi-round Noise | Single round-trip |
| Buffer allocation | Per-packet malloc | Zero-copy pool |
| Batch processing | No | 64 packets/batch |
| Packet capture | TUN device | NFQUEUE/PF/WinDivert |
| Transport | UDP only | QUIC + UDP fallback |
| Cross-platform | Separate implementations | Unified protocol |

### 🎭 MASQUE-Inspired Architecture

### 📦 Compression (Pure Rust, Enabled by Default)
- **Parallel LZ4 Compression** - Multi-threaded compression scales with CPU cores (10+ Gbps)
- **Per-Connection Dictionaries** - Learns per-flow patterns for 20-40% better compression
- **ROHC Header Compression** - 44% size reduction for UDP/IP headers
- UDP, TCP, IP, RTP, ESP, IPv6 profiles
- Fast state transitions (IR → FO → SO in 5 packets vs standard 10)
- LRU context eviction for inactive flows
- W-LSB delta encoding for sequence numbers
- **Enabled by default** - no configuration needed
- **SIMD-Accelerated** - AVX2/NEON when available
- **Intelligent Selection** - Automatically chooses best compression per packet
- **Smart Entropy Detection** - Shannon entropy + magic byte detection skips encrypted/compressed data
- Detects gzip, ZIP, LZ4, Zstd, TLS records, JPEG, PNG, MP4
- Entropy threshold: >7.5 bits/byte = skip compression

**ROHC Performance Impact:**
| Traffic Type | Without ROHC | With ROHC | Savings |
|--------------|--------------|-----------|--------|
| UDP Gaming (64B) | 62% header overhead | 3% | **59%** |
| VoIP RTP (160B) | 25% header overhead | 1% | **24%** |
| SSH keystrokes (80B) | 75% header overhead | 10% | **65%** |

### 🔒 Security & DDoS Protection
- **TLS 1.3** - Real certificate support with Let's Encrypt
- **Per-IP Rate Limiting** - Connection, PPS, and bandwidth limits
- **Auto-blocking** - Automatic IP blocking after violations
- **QUIC Security** - Stateless retry, address validation, anti-amplification

### 🌐 Infrastructure & Resilience
- **Connection Migration** - Seamless WiFi ↔ LTE handoff
- **Multi-Server Ready** - Relay mesh for scaling when needed
- **Predictive Prefetching** - DNS and connection pre-warming
- **Health Monitoring** - Automatic failover on relay issues

### 🚀 Server-to-Internet Optimizations
The relay server optimizes traffic from server to destination (your game server, websites, etc.):

| Optimization | Benefit | Implementation |
|--------------|---------|----------------|
| **BBR Congestion Control** | 2-25x better throughput on lossy links | `tcp_congestion_control = bbr` |
| **TCP Fast Open** | -1 RTT on repeat connections | `tcp_fastopen = 3` |
| **UDP GSO/GRO** | 64 packets per syscall | Kernel 4.18+ |
| **ECN (RFC 9000)** | Congestion signals without loss | DCTCP-style response |
| **Jumbo Frames** | 9000 MTU on datacenter NICs | Reduces header overhead |
| **NUMA-Aware** | Memory close to CPU | <100ns memory access |
| **Peering** | Direct routes to game servers | Latitude.sh Chicago |

**Server Kernel Tuning (Applied Automatically):**
```
net.core.rmem_max = 268MB # Large receive buffers
net.core.wmem_max = 268MB # Large send buffers
net.core.netdev_max_backlog = 500K # Handle burst traffic
net.ipv4.tcp_congestion_control = bbr # Google BBR
net.ipv4.tcp_fastopen = 3 # Client + server TFO
```

**Why This Matters:**
```
Without optimization: Server → 5 hops → ISP peering → 8 hops → Game Server
With Oxidize: Server → 2 hops → Direct peering → Game Server
(Latitude.sh has direct peering with major gaming networks)
```

### 📊 Observability

## Quick Start

### One-Click Client Install

```bash
# Install and auto-start (defaults to relay.oxd.sh:4433)
curl -fsSL https://raw.githubusercontent.com/gagansuie/oxidize/main/install.sh | sudo bash
```

```bash
# Or specify a custom server
curl -fsSL https://raw.githubusercontent.com/gagansuie/oxidize/main/install.sh | sudo bash -s -- relay.oxd.sh:4433
```

The installer handles everything: downloads binary, configures service, and starts automatically.

> **Review the script:** [install.sh](install.sh)

### Build from Source

```bash
# Build
cargo build --release

# Run server (on your relay server)
./target/release/oxidize-server --listen 0.0.0.0:4433

# Run client (defaults to relay.oxd.sh:4433)
./target/release/oxidize-client

# Or specify a custom server
./target/release/oxidize-client --server relay.oxd.sh:4433

# Run speed test
./target/release/oxidize-client --speedtest
```

## Configuration

Create `config.toml`:

```toml
max_connections = 10000
enable_compression = true
enable_tcp_acceleration = true
rate_limit_per_ip = 100

# ROHC header compression (enabled by default)
enable_rohc = true
rohc_max_size = 1400

# Congestion control (adaptive_ml, cubic, gaming)
congestion_algorithm = "adaptive_ml"

# Priority scheduling
enable_priority_scheduler = true

# Performance optimizations are always enabled:
# - Zero-copy buffer pooling
# - Lock-free stream handling
# - ACK batching (8 per batch)
# - Latency instrumentation
```

### Feature Interactions

| Feature Combo | Interaction | Status |
|--------------|-------------|--------|
| FEC + Compression | FEC adds redundancy before compression | ✅ Auto-adapts |
| ROHC + Small Packets | ROHC best for <200B packets | ✅ Auto-selects per packet |
| Zero-copy + Compression | Compression into pooled buffer | ✅ No conflict |
| Priority Scheduler + ACK Batching | Real-time traffic prioritized | ✅ ACKs respect priority |

### 🎮 Gaming Overhead Analysis

| Workload | Tick Rate | Tick Period | Oxidize Overhead |
|----------|-----------|-------------|------------------|
| Competitive FPS | 128 Hz | 7.8ms | **0.009%** |
| Standard Gaming | 64 Hz | 15.6ms | **0.004%** |
| VoIP (20ms frames) | 50 Hz | 20ms | **0.0035%** |
| Video Streaming | 60 Hz | 16.7ms | **0.004%** |

**Why it matters:** Batching and QUIC datagrams eliminate latency *spikes* - the micro-stutters from syscalls and head-of-line blocking that ruin gaming feel.

### When Oxidize Helps

- Mobile networks: +30-50% improvement (packet loss handling)
- Congested ISPs: +40-60% improvement (better routing)
- Gaming: +20-40% improvement (stable latency)
- API-heavy apps: +50-70% improvement (compression + multiplexing)

### When It Won't

- Already-optimal fiber connections
- Video streaming (already compressed)
- Local network traffic

**Honest benchmarks, no marketing BS.**

## Monitoring

```bash
# Metrics endpoint
curl http://localhost:9090/metrics
```

**Latency Metrics:**
```
║ Avg Process Latency: 0.7µs # Per-packet processing time
║ Avg Forward Latency: 12.3µs # Time to forward to destination
║ Avg Encode Latency: 0.2µs # Message encoding time

## Daemon Management

The daemon runs **OxTunnel** - our unified protocol that captures packets via NFQUEUE and tunnels them over QUIC:

### How OxTunnel Works (Linux)
```
App Traffic → NFQUEUE (kernel) → OxTunnel Batching → QUIC Datagrams → Relay Server
↓ ↓
TCP + UDP TCP: Connection proxy
captured UDP: Direct forward
```

### Features
- **Full traffic capture** - Intercepts **both TCP and UDP** at kernel level via NFQUEUE
- **TCP connection pooling** - Server maintains persistent TCP connections to destinations
- **UDP direct forwarding** - Low-latency UDP packet forwarding
- **64 packets/batch** - Reduces syscalls, improves throughput
- **QUIC datagrams** - Zero head-of-line blocking for gaming/VoIP
- **Pure userspace** - No kernel modules, no TUN devices
- **Same protocol as mobile** - Unified OxTunnel on all platforms

### Commands
```bash
# Check status
sudo systemctl status oxidize-daemon

# Start/Stop/Restart
sudo systemctl start oxidize-daemon
sudo systemctl stop oxidize-daemon
sudo systemctl restart oxidize-daemon

# View logs
sudo journalctl -u oxidize-daemon -f

# Manual run (for debugging)
sudo ./target/release/oxidize-daemon
```

### NFQUEUE iptables Rules
When connected, the daemon automatically configures rules for **both TCP and UDP**:
```bash
# Check active rules
sudo iptables -L OUTPUT -v -n --line-numbers

# Expected output shows both protocols captured:
# NFQUEUE udp -- 0.0.0.0/0 0.0.0.0/0 NFQUEUE num 0 bypass
# NFQUEUE tcp -- 0.0.0.0/0 0.0.0.0/0 NFQUEUE num 0 bypass
```

╠════════════════════════════════════════════════════════════════╣
║ XDP Mode: 10-25 Gbps (event-driven, low power) ║
║ Per-Packet Latency: <300ns (P99) ║
║ Zero-Copy: No memcpy in hot path ║
║ Lock-Free Rings: SPSC queues, no contention ║
║ Batch Processing: 64 packets per burst ║
║ CPU Pinning: Dedicated cores per queue ║
║ NUMA Aware: Memory allocation close to CPU ║
║ Huge Pages: 1GB/2MB pages for minimal TLB misses ║
╚════════════════════════════════════════════════════════════════╝
```

> **Note:** AF_XDP kernel bypass requires the `xdp` feature and Linux kernel 5.4+.
> Event-driven architecture with no dedicated CPU cores needed. See deployment guides for setup.
