Abstract:

In a general aspect, calibration is performed in a quantum computing system. In some cases, domains of a quantum computing system are identified, where the domains include respective domain control subsystems and respective subsets of quantum circuit devices in a quantum processor of the quantum computing system. Sets of measurements are obtained from one of the domains and stored in memory. Device characteristics of the quantum circuit devices of the domain are obtained based on the set of measurements, and the device characteristics are stored in a memory of the control system.

Shaun CRAMPTON - San Francisco CA, US

International Classification:

H04L 12/64
H04L 12/851
H04L 12/721
H04L 12/24

Abstract:

A controller node receives a list of a first plurality of flows programmed on a network switch. The controller node extracts a flow cookie value from a flow cookie data field of each flow in the first plurality of flows on the received list and calculates a session identifier on the basis of the extracted cookie values. At least one add flow command is transmitted from the controller node to the network switch to program a second plurality of flows on the network switch. The at least one add flow command comprises flow cookie values in the flow cookie data fields of each of the flows in the second plurality of flows which are set equal to the calculated session identifier. At least one delete flow command is transmitted from the controller node to the network switch to delete programming of the first plurality of flows on the network switch.

International Classification:

H04L 12/741

Abstract:

Measures, including methods, systems, non-transitory computer-readable storage mediums and computer programs for use in routing packet data. At a network switching device, a data packet is received from a device located upstream of the network switching device. The received data packet comprises routing data associated with a routing decision which has been taken for the data packet upstream of the network switching device. The routing data comprises an abstract media access control (MAC) address corresponding to a next hop destination for the data packet located downstream of the network switching device. At the network switching device, the abstract MAC address in the data packet is replaced with a real MAC address of the next hop downstream destination. At the network switching device, the data packet is forwarded towards the next hop downstream destination.

International Classification:

H04L 12/24
H04L 12/753
H04L 12/751

Abstract:

Described herein is an inference-based approach to process network route definitions, e.g. routes received from other network devices according to a defined routing protocol. In examples, at least one proposition is defined that relates to at least one property of the route. Probabilities are also defined in association with the proposition. A first probability may be indicative of a randomly-selected network route and a second probability may be indicative of randomly-selected network route that is suitable for use in routing network traffic. In certain examples, a probability that a given route is malicious or erroneous may be computed. Probabilities may be calculated by processing historical routing data, such as network route definitions that are labelled as suitable for routing traffic. Probabilities may also be evaluated cumulatively over multiple routing policy elements. Final actions may be made by applying a configurable range or threshold to an output confidence value.

International Classification:

H04L 12/721
H04L 12/26

Abstract:

Certain examples described herein provide a system and method for validating a routing function for a network device. In one example, a network device has a run-time policy engine, wherein the run-time policy engine implements a routing configuration file and the routing configuration file defines a routing function for network traffic. A file editor is also provided that loads the routing configuration file. The file editor has an editor policy engine that duplicates a functionality of the run-time policy engine. In one example, the routing configuration file has at least one validation portion that has one or more route statements with definitions indicative of expected routing function behavior. The file editor parses the routing configuration file by implementing the routing configuration file using the editor policy engine. The editor policy engine applies the routing function defined by the routing configuration file to the one or more route statements and indicates where a result of the routing function does not conform to the definitions indicative of expected routing function behavior. These examples may help to reduce routing errors due to configuration errors in network devices.
