Apache Traffic Control

Apache Traffic Control is an open-source platform for building and managing large-scale content delivery networks (CDNs). It is built around Apache Traffic Server and provides a distributed, scalable, and redundant architecture for efficiently delivering content to end users. Traffic Control includes a suite of integrated modules that handle routing, monitoring, configuration, and statistics, making it a comprehensive solution for CDN operators.

Features

• Reduced Latency: Caches and content are located closer to users, minimizing round-trip time.
• Bandwidth Optimization: Caching in memory and on disk reduces load on origin servers and network bottlenecks.
• Improved User Experience: Faster delivery and higher bandwidth enhance content quality and responsiveness.
• Modular Architecture: Includes Traffic Ops (API service), Traffic Router (DNS/HTTP redirection), Traffic Stats (real-time metrics), Traffic Portal (web GUI), and Traffic Monitor (cache health polling).
• Experimental Components: Grove, a high-performance HTTP cache written in Go, is available for live-focused caching.

Capabilities

• RESTful API Management: Traffic Ops provides full control over CDN configuration and monitoring.
• Dynamic Routing: Traffic Router uses DNS and HTTP302 to direct clients to optimal cache locations.
• Real-Time Monitoring: Traffic Monitor and Traffic Stats enable health checks and performance tracking.
• Web-Based Administration: Traffic Portal offers a user-friendly interface for managing CDN resources.
• Security and Authentication: Supports TLS certificate-based authentication and OAuth integration.

Benefits

• Scalability: Designed to support CDNs of all sizes, from small deployments to global networks.
• Flexibility: Modular design allows customization and integration with existing infrastructure.
• Reliability: Redundant architecture ensures high availability and fault tolerance.
• Operational Efficiency: Automated configuration and monitoring reduce manual overhead.
• Community Support: Maintained by the Apache Software Foundation with regular updates and active development.
