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).
