Abstract
Embodiments of the invention employ specially adapted P2MP and MP2P transmission techniques to communicate traffic of a TDM based SCADA system over an IP/MPLS based network. Advantageously, by specially adapting P2MP and MP2P transmission techniques to carry TDM based SCADA traffic over an IP/MPLS network, an existing TDM based SCADA system can be migrated to an IP/MPLS network and operated in an easy to manage and bandwidth efficient manner as compared to a solution that employs point-to-point connections between a SCADA master node and subsystems over an IP/MPLS network. Furthermore, since TDM based SCADA equipment would not need to be replaced with IP based SCADA equipment in such a migration, significant equipment and installation costs associated with such replacement can be avoided.
