Anycast-based internet protocol redirection to alleviate partial routing tables

摘要

Systems and methods are described that instruct routers having constrained hardware/memory to redirect all outbound traffic to a helper router. The helper router contains a full routing table that can forward any packet to its destination. In a large service provider network, helper routers may be distributed at multiple locations across the network. Since packets must detour through the helper router, the distributed helper routers minimize latency.
