Abstract: A system may allow for generic end user mobile devices to be operated using a virtualized personal device framework. The virtualized personal device framework may provide for a collective intelligence network platform that allows offloading of heavy computing processes onto virtual instance in a cloud network and enables crowd sourcing services for smart cities that may provide smart emergency services in which end-users collaborate.

Abstract: The concepts and technologies disclosed herein are directed to zero day attack detection. A system can monitor, by a sequence manager, a sequence of transaction requests. The sequence manager can determine whether a transaction request in the sequence is anomalous. In response to determining that the transaction request is anomalous, and before the allowing the system to process the transaction request, the sequence manager can provide the sequence of transaction requests to a sequence emulator. The sequence emulator can attempt to verify an output of the sequence of transaction requests. The sequence manager can receive a notification from the sequence emulator. The notification can indicate whether the output of the sequence of transaction requests can be verified. In response, the sequence manager can instruct the system to deny (if the output cannot be verified) or allow (if the output can be verified) processing of the sequence of transaction requests.

Abstract: The described technology is generally directed towards network slicing for private cellular networks (PCNs). Network slicing can be leveraged as described herein to meet security requirements and/or other policies applicable to PCNs. Network slices implemented according to this disclosure can comprise a private network slice, a public network slice, and a public safety network slice. User equipment can be provisioned with slice identifiers for the network slices, and applications at the user equipment can specify an appropriate slice identifier for their network communications. Network equipment can be configured to route application traffic to a specified slice and to allocate network resources according to the specified slice, as well as to implement security and other policies according to the specified slice.

Abstract: Aspects of the subject disclosure may include, for example, obtaining for a first path carrying first network traffic a corresponding first alternate path; obtaining for a second path carrying second network traffic a corresponding second alternate path, at least a first portion of the first alternate path being the same as at least a second portion of the second alternate path; responsive to a first detected failure on the first path, causing communication of first re-directed network traffic via the first alternate path instead of via the first path; responsive to a second detected failure on the second path, detecting whether total traffic, including the first re-directed network traffic, on the first portion of the first alternate path meets a threshold; responsive to the detected meeting of the threshold, obtaining for the second path a corresponding back-up alternate path; and causing communication of second re-directed network traffic via the back-up alternative path instead of via the second path. Other embodiments are disclosed.

Abstract: In one embodiment, a method includes identifying, by a packet analyzer, one or more silence packets within a network and initiating, by the packet analyzer, a replacement of the one or more silence packets with one or more performance silence packets. The one or more performance silence packets are transmitted between a first node of the network and a second node of the network during a silence period. The method further includes receiving, by the packet analyzer, information associated with the one or more performance silence packets; and analyzing, by the packet analyzer, a connection between the first node of the network and the second node of the network using the information associated with the one or more performance silence packets.

Abstract: A processing system of an autonomous aerial vehicle including at least one processor may obtain mapping data describing at least a portion of a facility, navigate, via the mapping data, to a space within the facility to perform an assigned task, and collect spatial sensor data within the space. The processing system may then detect, from the spatial sensor data, at least one object within the space, define a reserved zone within the space to perform the assigned task, based upon the at least one object that is detected, and present at least one of an audible announcement or a visual announcement of the reserved zone.

Abstract: Aspects of the subject disclosure may include, for example, a method in which a processing system detects user equipment (UE) in communication with a network via a serving cell of the network; the network is configured to facilitate communications by one or more terrestrial UEs and one or more aerial UEs. The system monitors messages from an aerial UE regarding detection of a cell other than the serving cell, and receives information from the aerial UE regarding the detected cell. The method further includes analyzing the information to estimate a first quantity associated with the detected cell location relative to the serving cell and a second quantity associated with a power received at the aerial UE from the detected cell. The method also includes determining, based on the analyzing, whether the aerial UE is an unauthorized aerial UE. Other embodiments are disclosed.

Abstract: The described technology is generally directed towards a transport protocol for latency sensitive applications. The disclosed transport protocol is “semi-reliable” in that it allows for specification of an importance of data being transmitted, thereby allowing important data to be sent reliably, while other data can be dropped if necessary, e.g., under bad network conditions. A deadline can be specified for such other data, and if the other data cannot be sent prior to the deadline, it can be dropped. Furthermore, the disclosed transport protocol can allow for early discovery of network jitter. A client device can send regular acknowledgments which identify most recently received data packets as well as a number of “heartbeat transmissions” received at the client device. A server device can use the acknowledgments to discover and respond to jitter.
