Abstract
An overlay network is enhanced to provide traffic delivery using anycast and end user mapping. An anycast IP address is associated with sets of forwarding machines positioned in the overlay network. These locations correspond with IP addresses for zero rated billing traffic. In response to receipt at a forwarding machine of a packet, the machine issues an end user mapping request to the mapping mechanism. The mapping request has an IP address associated with the client from which the end user request originates. The mapping mechanism resolves the request and provides a response to the request. The response is an IP address associated with a set of server machines distinct from the forwarding machine. The forwarding machine encapsulates the packet and proxies the connection to the identified server. The server receives the connection, decapsulates the request, and processes the packet. The server machine responds to the requesting client directly.
