Edge Network Architecture
The edge network in Hong Kong comprises a layer of servers that intercept user requests close to the source of traffic. The architecture employs a hierarchical routing model: first, requests are directed to the nearest edge node; then, if the content is not cached locally, the request is forwarded to the nearest origin server. This design reduces latency, lowers bandwidth costs, and improves overall user experience. Cloudflare also leverages its global Anycast IP system, ensuring that user traffic is routed to the optimal edge node across multiple paths.
Peering and Connectivity
Cloudflare engages in peering agreements with a spectrum of regional Internet service providers (ISPs) and backbone carriers. These agreements are crucial for maintaining high‑quality, low‑latency connections between the company’s data centers and the broader internet. The network also integrates with the Hong Kong Cable and Data Centre Infrastructure (HKCDCI), enabling direct fiber connections to Mainland China and other Asian markets. The strategic peering choices help mitigate bottlenecks and support the company’s resilience objectives.
