Abstract: Techniques for a proxy to replicate traffic being communicated between a client device and a destination device based on determining an outage or impairment in a LEO satellite network. The proxy may be communicating a traffic stream between a source device and a destination device using a primary WAN that includes the LEO satellite network. However, the proxy may determine that the primary WAN has experienced or will experience an outage or other impairment. In such examples, the proxy may then replicate the traffic stream and send the replicated traffic stream over a backup communication link. The backup communication link may a different path through the primary WAN, and/or may be a communication path through a secondary WAN. Once the outage or impairment has cleared, the proxy may stop replicating the traffic and again use the primary WAN to communicate traffic.

Abstract: Techniques for a low Earth orbit (LEO) satellite to route data through optimal satellite paths based on latency thresholds (and/or other QoS thresholds) for the application generating the data. The LEO satellite may identify the latency threshold from a data packet, where the latency threshold indicates an amount of time for the data packet to be relayed back down to a destination ground device. The LEO satellite determines available satellite paths through which data packets may be routed to destination ground stations. Further, the LEO satellite may determine latencies for transmitting traffic over the available satellite paths. The LEO satellite may compare the latency threshold for the data packet with the latencies of the available satellite paths, and select a satellite path that is optimal for transmitting the data packet. In this way, LEO satellites intelligently route data through satellite paths based on the type of traffic being transmitted.

Abstract: Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.

Abstract: Techniques are presented herein that validate integrity of a computing device. A command to a first processor of a security module of the computing device is received through an interface unit of the security module on a communication channel external to the computing device. A configuration of the security module cannot be changed by a second processor of the computing device which executes an operating system and at least one application on the computing device. In response to receiving the command, one or more memory devices of the computing device are directly accessed by the first processor independent from the second processor to validate integrity of the computing device.

Abstract: This disclosure describes techniques for predicting and accommodating for outages in a satellite network using crowdsourced data. An example method includes receiving outage data indicating first outages experienced by first endpoints in a first geographical region. The first outages, for instance, include interruptions in communication between first satellites and the first endpoints. The example method further includes predicting, based on the outage data, a second outage comprising an interruption in communication between at least one second satellite and a second endpoint in a second geographical region. Further, the example method includes causing the second endpoint to transmit user data over a secondary network in advance of the second outage.

Abstract: In one embodiment, an apparatus is disclosed that includes one or more device interfaces, a processor coupled to the one or more device interfaces and configured to execute a process, and a memory configured to store the process executable by the processor. The process when executed is operable to receive condition data regarding a measured condition of a zone of a data center. The process when executed is also operable to determine a visual effect for a portion of a light strip based on the condition data. The portion of the light strip is associated with the zone and is located in the zone. The process when executed is further operable to control the portion of the light strip to display the determined visual effect.

Abstract: This disclosure describes techniques for complying with a data sovereignty policy of data routed through a satellite network. An example method includes identifying data comprising a data sovereignty label indicating a first geographical region; determining that a coverage region of a satellite includes a first ground station in the first geographical region; determining that coverage region excludes a second ground station in a second geographical region; and based on determining that the coverage area includes the first ground station and excludes the second ground station, transmitting the data to the satellite.

Abstract: This disclosure describes techniques for tracking aircraft using a satellite network. An example method includes receiving ADS-B messages from multiple aircraft; determining that at least one of the ADS-B messages satisfies at least one condition; and in response to determining that at least one of the ADS-B messages satisfies the at least one condition, transmitting an alert. In some cases, a system transmits an instruction to perform the example method to at least one satellite and receives the alert.
