Abstract: According to an embodiment, a node comprises one or more processors operable to execute instructions to cause the node to perform operations. The operations comprise determining a link quality associated with each satellite link of a plurality of satellite links and applying load balancing to the plurality of satellite links. The load balancing is based at least in part on the respective link quality associated with each satellite link. The load balancing comprises determining which of the satellite links to include in an active set selected to communicate data to or from the node and, for each satellite link in the active set, determining a portion of the data to communicate via the respective satellite link. The operations further comprise transmitting or receiving the data via the satellite links in the active set. Each satellite link in the active set communicates its respective portion of the data.

Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a random IP address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a random IP address that cannot be used to identify the endpoint device or service. The client device may then communicate data packets to the server using the random IP address as the destination address, and a gateway that works in conjunction with DNS can convert the random IP address to the actual IP address of the server using NAT and forward the data packet onto the server.

Abstract: This disclosure describes techniques for selectively placing and maintaining sensitive workloads in subsystems that achieve a minimum level of trustworthiness. An example method includes identifying at least one trustworthiness requirement associated with an application and transmitting, to a first subsystem, a request for at least one trustworthiness characteristic of the first subsystem and at least one second subsystem connected to the first subsystem. A response indicating the at least one trustworthiness characteristic is received from the first subsystem. The example method further includes determining that the at least one trustworthiness characteristic satisfies the at least one trustworthiness requirement; and causing the application to operate on a mesh comprising the first subsystem and the at least one second subsystem.

Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

Abstract: An application monitoring system for collecting, utilizing, and/or exchanging state information (e.g., application state and network state), configuration information, and/or other information to make network optimizations for applications orchestrated by an application orchestration system. The application monitoring system may include an application orchestrator discovery component that is configured to determine a presence of an application orchestration system for orchestrating applications. The application monitoring system may also include one or more application watch components for monitoring, among other things, application state, application configuration, and/or application replicas. The application monitoring system may further include a network state propagation component configured to provide network state information to the orchestration system.

Abstract: Described herein are techniques for implementing a low earth orbit (LEO) satellite network and routing communications (e.g., packets) over that network. In embodiments, the techniques may comprise receiving, at a first ground station computing device, a request to determine destination information for a communication, determining, at the first ground station computing device based on information about the communication, a target computing device to which the communication is to be routed, determining, at the first ground station computing based on the target computing device, a location of a destination ground station, determining, at the first ground station computing by mapping orbital data to the location of the destination ground station, a destination satellite, generating the destination information to include at least an address for the destination satellite, and providing the destination information in response to the request.

Abstract: Presented herein are techniques to facilitate electronic profile management by an enterprise entity in which the enterprise entity can utilize an enterprise infrastructure to provision one or more electronic profiles for one or more enterprise device(s). In one example, a method is provided that may include determining, by a management node of an enterprise network, whether a user equipment (UE) supports an electronic profile capability and a wireless wide area access network connectivity capability; and based on determining that the UE supports the electronic profile capability and the wireless wide area access network connectivity capability, providing, by the management node, at least one electronic profile to the UE via a wireless local area access network of the enterprise network, wherein the at least one electronic profile enables the UE to connect to at least one wireless wide area access network of the enterprise network.

Abstract: Systems, methods, and computer-readable media for controlling data transmission in TCP subflows of a MPTCP connection based on monetary cost. A low cost link and a high cost link of TCP subflows of a MPTCP connection formed between a first MPTCP peer and a second MPTCP peer can be identified. A congestion level on the low cost link can be determined based on feedback from a TCP congestion control mechanism for the MPTCP connection. Further, whether to send a data packet over the low cost link of the high cost link based on the congestion level on the low cost link can be determined. As follows, the data packet can be sent over the low cost link connection if it is determined to send the data packet over the low cost link.
