Abstract: Disclosed embodiments provide techniques for computer networks infrastructure automatic convergence. The network devices are enabled to communicate with other adjacent network devices, independently of the device type, about detected changes that could affect them and together generate consensus utilizing a blockchain mechanism about the configuration changes that are accepted. A priority table specifies a priority for various device classes on a network. The devices, in response to a new network topology, determine if a new device configuration is necessary. When a new device configuration is necessary, data corresponding to the new device configuration is put into a blockchain block and appended to a network blockchain that is maintained by one or more nodes (devices) on the network. In this way, an immutable history of network configurations is maintained, improving network security and reliability.

Abstract: A method, computer system, and a computer program product for accessing data in a network is provided. The present invention may include reading a control blockchain, by a non-trusted node, to enable the non-trusted node to read an asset from a trusted node blockchain on a trusted node.

Abstract: A media-defined optical logic circuit composed of a set of light-transmitting polyhedral prisms arranged so that a pair of adjacent prisms can exchange photonic signals through adjacent surfaces. Each prism contains one or more quantum dots that, when excited by a photonic signal received from an adjacent prism, respond by emitting light that becomes an incoming photonic signal for an adjacent prism. Photonic signals are propagated through the circuit in this manner along light-guide paths created by shading certain surfaces to render them fully or partially opaque. The prisms and shading are arranged such that the circuit performs a certain logic function. When the circuit receives a set of photonic input signals representing a binary input value, the circuit responds by emitting a set of photonic output signals that represent a binary output value determined by performing the logic function upon the binary input value.

The driving profile can be categorized into a driving pattern category. A plurality of candidate travel routes for the driver to reach an intended destination can be identified and, for each of the candidate travel routes, a plurality of route segments can be identified.

Route segments for which the probability that the current driving characteristics of the driver will cause the traffic accident exceeds a threshold value can be determined. A notification can be communicated to the driver or vehicle indicating such probability.
