Abstract: Dynamically altering routing decisions of IP packets 410 being sent through a network comprising extending the packet to add a routing script, wherein routing requirements and decisions of a client are stored in the routing script (smart packet payload 422), and at a network node, extracting and executing the routing script to obtain script results, changing a routing decision based on the script results and delivering the extended packet to a destination based on the changed routing decision. The routing decision making is shifted from the intermediate routing devices to the sender side of the network communication in order to exceed limitations of existing routing protocols by expressing certain conditions and actions in a smart packet 420, enabling routing decisions to be made at compatible smart routers on the path of the packet. The invention may be implemented to coexist with other existing routing protocols or may completely replace them.
