Using the ALTO Service, networking applications can request through the ALTO protocol information about the underlying network topology from the ISP or Content Provider. The ALTO Service provides information such as preferences of network resources with the goal of modifying network resource consumption patterns while maintaining or improving application performance. This document describes, in one example, an ALTO server that intersects network and cost maps for a first network with network and cost maps for a second network to generate a master cost map that includes one or more master cost entries that each represent a cost to traverse a network from an endpoint in the first network to an endpoint in the second network. Using the master cost map, a redirector may select a preferred node in the first network with which to service a content request received from a host in the second network.

Application-layer traffic optimization service spanning multiple networks

Techniques are described for providing secure network address translation (NAT) in a NAT device that provides endpoint-independent mapping (EIM) and endpoint-independent filtering (EIF) operations.

Secure network address translation

An example network system includes network interfaces, a data repository, a forwarding structure, a service element, and a forwarding element. The forwarding element is configured to receive a first packet having header information via a tunnel over the first network with one of the networking interfaces, pass the first packet to the service element, receive a second packet from the service element, and forward the second packet via the network interfaces to the second network, wherein the first packet conforms to the first network-layer protocol, and wherein the second packet conforms to the second network-layer protocol. The service element is configured to transform the first packet from a format conforming with the first network-layer protocol into the second packet having a format conforming with the second network-layer protocol, and direct the second packet to the forwarding element.
