SYSTEM AND METHOD FOR ESTABLISHING RELIABLE TIME-SENSITIVE NETWORKS
First Claim
1. A communication system comprising:
- one or more processors configured to determine a communication risk value for each path of multiple paths between nodes and links between the nodes within a time-sensitive network, the one or more processors also configured to determine that at least one of the paths is a low reliability path due to the low reliability path having a communication risk value than one or more other paths in the time-sensitive network,wherein the one or more processors also are configured to establish a redundant path of the paths that bypasses the low reliability path such that the redundant path includes at least one different link or node from the low reliability path, andwherein the one or more processors also are configured to control the time-sensitive network to communicate duplicate copies of a data frame in parallel along both the redundant path and the low reliability path between a publishing device and a listening device within a designated time window according to a schedule of the time-sensitive network.

Abstract
A communication system includes one or more processors that determine a communication risk value for each path of multiple paths within a time-sensitive network. The multiple paths are defined by multiple nodes and links that communicatively connect the nodes. The processors establish a redundant path of the paths that bypasses a low reliability path of the paths. The redundant path includes at least one different link or node from the low reliability path. The processors control the time-sensitive network to communicate duplicate copies of a data frame in parallel along both the redundant path and the low reliability path to increase a likelihood that the data frame is received at a listening device from a publishing device within a designated time window according to a schedule of the time-sensitive network.

9. A method comprising:
-
determining a communication risk value for each path of multiple paths between nodes and links between the nodes within a time-sensitive network; determining that at least one of the paths is a low reliability path due to the low reliability path having a greater communication risk value than one or more other paths in the time-sensitive network; establishing a redundant path of the paths that bypasses the low reliability path such that the redundant path includes at least one different link or node from the low reliability path; and directing the time-sensitive network to communicate duplicate copies of a data frame in parallel along both the redundant path and the low reliability path between a publishing device and a listening device within a designated time window according to a schedule of the time-sensitive network. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A communication system comprising:
-
a time-sensitive network including plural network paths formed by nodes interconnected by communication links, the nodes configured to receive and forward data frames of a message between each other along the communication links to communicate the message originating at a publishing device to one or more listening devices within a designated time window according to a schedule of the time-sensitive network; and one or more processors configured to determine communication risk values for two or more of the network paths within a time-sensitive network that communicatively couple the publishing device with the one or more listening devices, wherein the one or more processors also are configured to compare the communication risk values of the paths and to establish a redundant path that communicatively couples the publishing device with the one or more listening devices from one or more of the nodes and two or more of the communication links already existing in the time-sensitive network based on the communication risk values that are compared, wherein the redundant path is established to bypass at least one other network path of the network paths between the publishing device and the one or more listening devices, and wherein the one or more processors also are configured to control the time-sensitive network to communicate duplicate copies of at least one of the data frames in parallel along both the redundant path and the at least one other network path from the publishing device to the one or more listening devices within the designated time window of the schedule of the time-sensitive network. - View Dependent Claims (17, 18, 19, 20)
