About this network

Autonomous System 4809 (CHINATELECOM-CORE-WAN-CN2) is the core of CN2, China Telecom's "Next Generation Carrier Network" — a premium backbone kept separate from the mass-market ChinaNet network.

What it's used for

• Carrier backbone and transit, particularly for international routes in and out of China and for premium enterprise and wholesale services.

Notable

• Backbone infrastructure, not an access network: the addresses here are router interfaces and core links rather than customer endpoints.
• CN2 is widely regarded as China Telecom's higher-quality path for cross-border traffic, and is routinely distinguished from ChinaNet — see AS4134 for the mass-market "163" backbone.

Interesting

• CN2 routes are a perennial topic among operators serving Chinese users, because which of China Telecom's two backbones a route lands on can make a large difference to latency and loss on international paths.
