Abstract
An Application Layer Traffic Optimization (ALTO) node comprising a processor configured to import a first set of network information from one or more software defined networking (SDN) nodes, aggregate the network information received from the SDN nodes, calculate a plurality of traffic optimization decisions based on the aggregated network information, and forward the traffic optimization decisions to the SDN nodes. Also disclosed is a method for optimizing traffic using a SDN node and an Application Layer Traffic Optimization (ALTO) node, the method comprising receiving a request for network resources from a node, obtaining a plurality of traffic optimization information from the ALTO node, negotiating one or more paths with a second SDN node using the traffic optimization information received from the ALTO node, constructing the paths, and sending a response to the node that indicates the node may forward packets via one of the paths.
