Abstract
Systems and methods providing a route optimization mechanism for transmitting data traffic across different autonomous systems based on real-time route performance detection. Regarding a request for routing data between a source node that is coupled to a first autonomous system and a destination node located in a second autonomous system, each of a plurality of edge nodes in the first autonomous system operates to detect and evaluate real-time route performance. The evaluation results are compared and used to select an edge node and an associated link for transporting data between the source node and the destination node. The route optimization mechanism can be adopted in an SDN-based or other virtual network autonomous system.
