A system generates a tailored contact plan using a set of contact commands that represent a contact plan of communication opportunities between nodes in a network, an identification of restricted nodes in the network, and an identification of a target node. The system processes the records in the contact plan by writing a record to the tailored contact plan when the record is not a contact command; or writing the record to the tailored contact plan when the record includes the contact command, and a source node in the record is not a restricted node or the source node in the record is the target node; or writing the record to the tailored contact plan when the record includes the contact command and the destination node in the record is the target node. The target node uses the tailored contact plan to route data through the network.
