Source-based network routing

A message center for source-based message routing may include a processor and a memory communicatively connected to the processor. The processor may be configured to receive a first message having a first message transfer layer indicating a first destination address and a first message transaction layer, receive a second message having a second message transfer layer indicating a second destination address and a second message transaction layer indicating an alternate routing, read at least the first message transfer layer of the first message, read at least the second message transaction layer of the second message, route the first message based in part on the first destination address of the first message transfer layer, and route the second message based in part on the second destination address of the second message transfer layer and the alternate routing of the second message transaction layer.
