Abstract: In one embodiment, a method comprises: storing, by a computing device in a non-deterministic data network, a plurality of data packets originated by a source device into a mass storage medium associated with the computing device; receiving, by the computing device, a data request originated by an access point device providing deterministic reachability to a deterministic device in a deterministic data network providing reachability to multiple deterministic devices, the request specifying one or more deterministic constraints associated with reaching the deterministic device; and supplying, by the computing device, a selected one of the data packets to the access point device for delivery of data stored therein to the deterministic device according to the one or more deterministic constraints.

Abstract: A methodology includes determining a first delay between a first relay and a first label edge router, a second delay between a second relay and a second label edge router, and a third delay of a label-switched path between the first label edge router and the second label edge router. Based on the first, second, and third delays, it is determined whether an end-to-end latency between the first relay and the second relay exceeds an end-to-end latency threshold.

Abstract: In one embodiment, a method comprises a topology processor generating a power grid topology model of a power grid topology controlled via a communications network having a corresponding communications architecture overlying the power grid topology. The topology processor generates a communications architecture model of the communications architecture. In response to receiving a request for executing a change in at least a portion of the power grid topology, the topology processor identifies power grid topology model data associated with the portion of the power grid topology, and identifies communications architecture model data identifying a corresponding portion of the communications architecture associated with the portion of the power grid topology.

Abstract: A technique for key sharing among multiple key servers connected to one another over a communication network is provided herein. Each key sever of the multiple key servers stores respective cryptographic keys, and provides the keys to a local device group connected with the key server, to enable the device group to encrypt messages with the keys. Each key server acts as a proxy for the other key servers in order to receive other keys from the other key servers over the network, and provide the other keys to the device group for use to decrypt messages received from other local device groups respectively connected with the other key servers that were encrypted with the other keys and to check message integrity. The multiple key servers may share keys with each other directly, or alternatively, indirectly through a central key server, as needed to support secure communications between their respective device groups.
