Abstract: A network-management system capable of reducing negative impacts of natural disasters on network services. In an example embodiment, in response to an indication of potential failure of one or more network resources in a meteorological event, the network controller operates to orchestrate re-hosting of affected VNFs and perform SDN-based reconfiguration of switches to adapt the traffic flows to the re-hosted VNFs. The indication of potential failure can be provided, e.g., by a specialized application capable of estimating the probabilities of failure for individual network resources based on a plurality of inputs, such as digital weather forecasts for the corresponding geographical area, geographical locations of individual network resources, tolerances of different network resources to specific environmental conditions, previous history of network damage in the same geographical area, alerts from power suppliers, etc.

Abstract: Method of dynamically assigning storage locations starts with the processor updating first user's home location data. Processor selects communication session between first user and second user and determines second user's home location data. Processor determines a session location data that indicates current storage location that stores data of communication session received from first and second client devices. Processor identifies available data storage locations based on first user and second user's home location data and determines whether to update the session location data based on an average of a distance over network fiber using the first user and second user's home locations, current storage location, and available storage locations. In response to determining to update the session location data, processor updates session location data to indicate one of the available storage locations, and causes transfer of data of communication session to one of the available storage locations.

Abstract: Methods, systems, and devices are provided herein for a mechanism to identify link down reasons. As described herein, a first port of a first peer device may be determined to have unexpectedly changed to a port down state. Subsequently, a topology file may be referenced to identify a second port of a second peer device with which the first peer device is intended to have a link if not for the first port being in a port down state. In some examples, port settings of the first port may be compared with port settings of the second port. If a port setting for the first port mismatches an associated port setting for the second port, an alert message may be transmitted to a network administrator indicating this mismatch as a possible reason for the first port being in the port down state.

Abstract: Techniques for automating the provisioning, configuring, and onboarding of network devices into a cloud management platform. The cloud management platform can be used to manage network devices that are provisioned in on-premise environments, cloud environments, and/or hybrid environments. However, it can be a cumbersome and error-prone process for a user to manually configure each of the network devices with connectivity settings needed to be managed by the cloud management platform. The techniques described herein provide an automated process to distribute connectivity information to the network devices to allow them to be managed by the cloud management platform. Once connected to the cloud management platform, the techniques described herein further include automating the process for attaching the network devices with the appropriate user account registered with the cloud management platform.

When malicious activity is detected, the system may track the malicious activity, using the network data, to an earliest connection date of a client device from where the malicious activity potentially originated. The earliest connection date may indicate a potential start date of the malicious activity.

Abstract: Switching among sensor feeds for optimum performance includes disposing a processor in communication with sensors, each said sensor providing a primary data stream. A data stream standard is established in the processor. The primary data streams are communicated from the sensors to the processor, and are compared against the data stream in the processor. A secondary data stream is selected from among the primary data streams or synthesized from one or more of the primary data streams, based on which primary data stream(s) most closely match the data stream standard. The secondary data stream is communicated to a data stream recipient. The data stream recipient may identify input in the secondary data stream, and an input executor may execute control commands corresponding to the input so as to control a device or system.

Abstract: An exposure of a user of a network to an adverse network event can be estimated based on network topology data, network traffic associated with the user, and network performance data. A subgraph of the network topology including candidate paths through the network devices and links of the topology that were traversed by the user's network traffic can be estimated using the network topology data and the network traffic data associated with the user. Using the network performance data, an adverse network event can be mapped on the candidate paths of the subgraph to determine an impact of the adverse network event on the user's network traffic. Upon determining that the adverse network event impacts the user, the user can be notified regarding the adverse network event. Optionally, actions to reduce the impact of the network event on the user can be performed.

Abstract: Described embodiments provide for dynamically optimizing the number of application layer streams that may be multiplexed into a single transport layer connection, providing the advantages of application layer multiplexing without incurring unnecessary congestion-based network delays. A device may monitor net bandwidth and packet loss rates for a connection, and may dynamically increase and decrease a number of concurrent application layer streams to balance throughput and congestion avoidance. As congestion increases, the device may reduce concurrent stream limits in order to spawn additional transport layer connections, allowing faster congestion recovery and reduced performance impairment.
