The content delivery system can consider various demand-based parameters when determining when and how to scale the cache fleet, including the overall demand (expected or observed) for all content available for delivery by the content delivery system, the demand for a subset of content or individual content items relative to the demand for other subsets of content or individual content items, etc. When content servers are removed from the cache fleet, snapshots of the content caches of the content servers can be stored to a persistent data store, and then restored to content servers when content servers are added to the cache fleet. |

Media streaming
Media streaming is more efficient in terms of transmission bitrate consumption, transmission latency and/or fair trade of transmission capacity among several by pushing media content rather than the client pulling media content from the server. Pushing media content to the client at a varying bitrate enables to shift, at least partially, the control over the streaming from the client towards the server. The server may continue to push segments of the media content to the client even without receiving explicit queries or directives for these segments thereby reducing upstream bandwidth consumption. As far as the bitrate adaption is concerned, the server may act as a slave remotely controlled by the client in that media content is pushed at a bitrate depending on the client's most recently sent information such as reception situation information explicitly indicating the bitrate to be used. |

Detecting emergent abnormal behavior in a computer network faster and more accurately allows for the security of the network against malicious parties to be improved. To detect abnormal behavior, outbound traffic is examined from across several devices and processes in the network to identify rarely communicated-with destinations that are associated with rarely-executed processes. As a given destination and process is used more frequently over time by the network, the level of suspicion associated with that destination and process is lowered as large groups of devices are expected to behave the same when operating properly and not under the control of a malicious party. Analysts are alerted in near real-time to the destinations associated with the activities deemed most suspicious. |

System and method for real-time load balancing of network packets
Internet protocol packets are statelessly identified as associated with a particular session-instance by identifying a key, or session-instance identifier, within the data (or payload) portion of a user plane packet.

Using this stateless identification, transmitted user plane packets are automatically routed at the transmission speed of the transmission link using a method that automatically balances the analysis processing load between network probes. The load is balanced by routing the user plane packet to a network probe that is either already analyzing the session-instance or by routing the user plane packet to a system that has processing capacity to analyze a new session-instance. The network probe then analyzes the user plane packet and the session-instance to measure the quality of the user experience of the session-instance and performance of the network. |

Determining formal models using weighting factors for computing elements in multi-cloud environments
Techniques for deploying, monitoring, and modifying network topologies operating across multi-domain environments using formal models and weighting factors assigned to computing elements in the network topologies. The weighting factors restrict or allow the movement of various computing elements and/or element groupings to prevent undesirable disruptions or outages in the network topologies. Generally, the weighting factors may be determined based on an amount of disruption experienced in the network topologies if the corresponding computing element or grouping was migrated. As the amount of disruption caused by modifying a particular computing element increases, the weighting factor represents a greater measure of resistivity for migrating the computing element. In this way, topology deployment systems may allow, or disallow, the modification of particular computing elements based on weighting factors. Thus, the amount of disruption in the functioning of network topologies may be considered when optimizing the allocation of computing elements across multi-domain environments. |

Magneto-ionic device with a solid state proton pump and methods for using the same
A spintronic device controls both the electrical charge and the spin of electrons to transmit, process, and store information. The control of electron spin provides additional degrees of freedom to modify the electric and magnetic properties of materials such as magnetic anisotropy. However, the development and integration of spintronic devices has been limited, in part, by the lack of a robust approach to electrically gate magnetism. Conventional approaches to gating magnetism either exhibit impractically small changes to the properties of a magnet or limited operating lifetime due to material degradation. Here, a magneto-ionic device operates using a hydrogen-gated magneto-ionic mechanism to overcome these shortcomings. A gate voltage applied to the magneto-ionic device causes protons to move towards a magnetic layer where the protons reduce to hydrogen. The presence of hydrogen and protons leads to large changes in the magnetic layer without degradation. This voltage-induced process is reversible. |

The beneficial interaction between an appropriately designed top protrusion array and metal-less reflector/electrode back contact (R/EBC) serves (1) to refract the incoming light thereby providing photons with an advantageous larger momentum component parallel to the plane of the back (R/EBC) contact and (2) to provide optical impedance matching for the short wavelength incoming light. The metal-less reflector/back electrode operates as a back light reflector and counter electrode to the periodic array of dome or dome-like structures. A substrate supports the metal-less reflector/back electrode. |
