Abstract: A method is performed by a network controller that is configured to control routers configured to forward a multicast flow downstream from a first hop router that is a root of a multicast tree formed by the routers to last hop routers that terminate branches of the multicast tree, respectively. The method includes collecting operational configuration information from the routers and constructing a topological view of the multicast tree based on the operational configuration information; causing the routers to forward multicast probes downstream from the first hop router along all of the branches toward the last hop routers to trace the multicast tree; receiving, from particular ones of the last hop routers that received the multicast probes, indications that the multicast probes were received; and detecting failures in the multicast tree based on the indications and the topological view.

Abstract: Techniques and mechanisms for a control plane approach for dense topologies that focusses on discovering shared ECMP groups in the control plane independent of per-prefix learning and then learning prefixes via these shared ECMP groups instead of learning prefixes via one next-hop at a time. In dense topologies, this approach helps minimize BGP path scale, corresponding signaling and enables control plane scaling that is an order of magnitude higher than a traditional eBGP control plane. During link and node topology changes, the described control plane approach enables control plane signaling that is prefix independent and an order of magnitude lower. A control plane approach to path-list sharing and prefix independent signaling on link and node topology changes enables prefix independent convergence (PIC) in scenarios that would not be possible otherwise with traditional FIB driven path-list sharing and PIC.

Abstract: A baggage handling system is described. The baggage handling system may include cameras. Video from the cameras may be automatically monitored. The video may be automatically monitored in real time across the entire journey of the baggage. The baggage handling system may provide an automated approach to identify theft of airport bags\luggage without manual effort required by humans. The bags may then be safely transported through an airport without theft or tampering. The automated surveillance and responding system may not depend on airport staff to monitor for baggage theft. The automated surveillance and responding system may detect multiple types of baggage theft/tampering.

Abstract: Techniques for building, validating, and utilizing custom database software in a shared management environment are described. A database customization service allows users to provide database installation files as part of a configuration to generate a custom database engine version. The creation of custom database engine versions may be governed by policy, and the database customization service may provide recommendations for creating custom database engine versions according to various criteria. The custom database engine version can be built, and its functionality and correctness verified. Users may launch database instances using these custom database engine versions that can be managed under a shared management scheme where both users and the database customization service can perform host-level management.

Abstract: Various technologies described herein pertain to routing an autonomous vehicle based upon risk of takeover of the autonomous vehicle by a human operator. A computing system receives an origin location and a destination location of the autonomous vehicle. The computing system identifies a route for the autonomous vehicle to follow from the origin location to the destination location based upon output of a computer-implemented model. The computer-implemented model is generated based upon labeled data indicative of instances in which autonomous vehicles are observed to transition from operating autonomously to operating based upon conduction by human operators while the autonomous vehicles are executing predefined maneuvers. The computer-implemented model takes, as input, an indication of a maneuver in the predefined maneuvers that is performed by the autonomous vehicle when the autonomous vehicle follows a candidate route.
