Disclosed are techniques for routing messages from a message delivery network (MDN) to one of a plurality of end user carriers, wherein there are a plurality of message routes capable of servicing each end user carrier. An MDN may receive a message from a sending message service provider. The MDN may identify a destination end user carrier servicing the end user device for the message. The MDN may produce a rank ordered list of message routes from the MDN to the destination end user carrier by solving a linear constrained optimization model configured to converge upon an optimized ranking of message routes from the MDN to the plurality of end user carriers. The MDN may then attach the rank ordered list of message routes to the message before forwarding the message to a gateway within the MDN. The gateway may then initially attempt delivery of the message using the highest ranked message route from the rank ordered list of message routes. If the delivery attempt fails, the next highest ranked message route may be attempted until the message is delivered or no other message routes are available to try. Other embodiments are described herein.

Techniques for routing messages through a message delivery network

A message delivery network may receive a message from a sending message service provider. The message delivery network may identify an end user carrier servicing the end user device for the message. The message delivery network may retrieve a pre-determined rank ordered list of message routes from the message delivery network to the end user carrier. The message delivery network may determine whether each message route is currently unavailable or demonstrating poor deliverability. The message delivery network may de-prioritize the message routes that are demonstrating poor deliverability. The message delivery network may update the rank ordered list of message routes based on the de-prioritized message routes. The message delivery network may attach the updated rank ordered list of message routes to the message. The message delivery network may forward the message to a gateway within the message delivery network. The gateway may deliver the message using the highest ranked message route. Other embodiments are described herein.
