Content Delivery Network

To distribute content across the Internet efficiently, companies have multiple Points of Presence over the world. Every such point acts as a BGP Leaf Node. BIRD easily handles this task and propagates routing information to the Internet.

BIRD can be also configured as a Route Collector to have precise data for analysis and network settings tweaking.

Internet Service Provider

In large networks with multiple uplinks and peerings, BIRD as Route Reflector reduces configuration complexity and allows for fast BGP route exchange.

Providers who prefer running a white-box hardware also can deploy BIRD there and have a completely open-source routing inside their network.
