Abstract: A network management agent, device or module determine the network topology of a communication network based on at least one neighbor network or end device identity and corresponding network link communication delay collected from, determined by, and stored in a Management Information Base of, at least one first network device of the communication network. Neighbor identities and communication delays are determined according to the IEEE 1588 standard.

Abstract: A method and system are provided for securing messages within a communication network of an industrial process control system, such as a substation automation system. A multi-block message to be transmitted via a communication network is secured by a block-based authentication, encryption and/or integrity information. Only residue of the previous block in the form of block-based information is needed to generate the block based information of the next block. Therefore, the previous block can already be transmitted while block-based information of the next block is generated. The method and system of the present disclosure enable on-the-fly authentication of the multi-block message and authentication at an increased rate.

Abstract: Exemplary embodiments are directed to a communication network interconnecting a plurality of synchronized nodes, where regular frames including time-critical data are transmitted periodically or cyclically, and sporadic frames are transmitted non-periodically or occasionally. For example, each node can transmit a regular frame at the beginning of a transmission period common to, and synchronized among, all nodes. Another node then receives regular frames from its first neighboring node, and forwards the frames within the same transmission period and with the shortest delay, to a second neighboring node. Furthermore, each node actively delays transmission of any sporadic frame, whether originating from an application hosted by the node itself or whether received from a neighboring node, until forwarding of all received regular frames is completed.
