Routing System

The Trunk network uses a sophisticated routing system to efficiently direct traffic and manage network communications.

Routing Overview

Core Concepts

1. Route Resolution

Routes are resolved using:

interface RouteResolution {
  path: string[];
  weight: number;
  latency: number;
  hops: number;
}

2. Routing Table

Example routing table structure:

const routingTable = {
  nodes: Map<NodeId, NodeInfo>,
  paths: Map<PathId, Path>,
  metrics: {
    latency: number,
    bandwidth: number,
    reliability: number
  }
};

Routing Algorithms

1. Path Selection

class PathSelector {
  selectOptimalPath(source, destination, requirements) {
    // Consider:
    // - Network latency
    // - Node capacity
    // - Geographic location
    // - Current load
    return bestPath;
  }
}

2. Load Balancing

The network implements adaptive load balancing:

  • Round-robin distribution
  • Weighted load balancing
  • Dynamic capacity adjustment
  • Geographic distribution

Route Types

  1. Direct Routes

    • Point-to-point connections
    • Minimal latency
    • High priority traffic
  2. Mesh Routes

    • Multiple path options
    • Fault tolerance
    • Load distribution
  3. Broadcast Routes

    • Network-wide distribution
    • Consensus messages
    • System announcements

Implementation

Basic Router Setup

import { TrunkRouter } from '@trunk/network';

const router = new TrunkRouter({
  mode: 'dynamic',
  optimization: 'latency',
  failover: true
});

router.on('pathChange', (oldPath, newPath) => {
  console.log('Route changed:', {
    from: oldPath,
    to: newPath,
    reason: 'performance optimization'
  });
});

Route Configuration

const routeConfig = {
  priority: 'high',
  maxLatency: 100, // ms
  redundancy: 2,   // backup paths
  security: {
    encryption: true,
    verification: true
  }
};

Performance Optimization

1. Caching

class RouteCache {
  constructor() {
    this.cache = new Map();
    this.ttl = 60000; // 1 minute
  }

  get(path) {
    return this.cache.get(path);
  }

  set(path, route) {
    this.cache.set(path, {
      route,
      timestamp: Date.now()
    });
  }
}

2. Metrics Collection

MetricDescriptionTarget
LatencyRound-trip time< 50ms
BandwidthAvailable capacity> 100Mbps
ReliabilityUptime percentage99.9%

Error Handling

Common routing issues and solutions:

Network Partitions

async function handlePartition(partition) {
  // Detect partition
  // Reroute traffic
  // Notify affected nodes
  // Attempt recovery
}

Node Failures

async function handleNodeFailure(node) {
  // Remove from routing table
  // Update affected routes
  // Notify dependent nodes
  // Begin recovery process
}

Best Practices

  1. Regular Updates

    • Update routing tables frequently
    • Monitor network conditions
    • Adjust weights dynamically
  2. Security

    • Verify route authenticity
    • Encrypt route updates
    • Monitor for anomalies
