System and method for providing data transport Quality of Service (QoS) assurances in homogeneous and heterogeneous communication networks consisting of one or more communication interface types. The system includes Subnet Managers for managing the resources of nodes within the subnets and Flow Managers for managing the communication flows between the nodes. A Real-time Reservation Transport Protocol (RRTP) establishes the resource reservations and QoS transport services for the communication flow payload over the reserved paths. The communication flows are protected against topological variations in the network, such as from node mobility. QoS assurances are also provided to secure communication flows through interoperation with security protocols, such as Internet Protocol Security (IPsec), or encryption devices, such as High Assurance Internet Protocol Encryptor (HAIPE).

High performance data transport system and method

System and method for topology management of dynamic ad hoc wireless communication networks. The network nodes are organized in a multi-level hierarchical architecture whereby the nodes at each level are managed by nodes at the next higher level. In a three-layer network, leaf nodes populate the lowest level, cluster head nodes the intermediate level, and regional head nodes the highest level. Priority-based backbone tree paths are constructed by selecting and connecting high capability nodes, such that the unselected nodes are one-hop away from a connected node. In a two backbone tree path construction, a primary backbone tree path carries the high priority traffic and a secondary backbone tree path carries the lower priority traffic. The connectivities of the backbone tree paths are maintained dynamically. So also are high priority traffic flows using the Dynamic Priority Threshold mechanism with High Fidelity Monitoring and traffic siphoning via unutilized network resources.
