An apparatus, system, and method for balancing traffic loads on beam outroutes that contain both multicast and unicast traffic. An outroute is designated for supplying at least multicast traffic within a beam of a satellite communication system. Terminals interested in receiving the multicast traffic are moved to the designated outroute. Traffic loads on all outroutes within the beam, including the designated outroute, are compared to determine if variations in the traffic loads exceed a predetermined threshold. A load balancing routine is performed to redistribute the traffic loads on all outroutes, while excluding any terminal that is actively receiving the multicast traffic from the load balancing routine.

A method and corresponding system for implementing Virtual Network Function (VNF) performance monitoring is provided. The method includes that: an Element Management (EM) receives a threshold policy of a VNF performance monitoring threshold sent by a Network Management (NM) or an Operation Support System (OSS); the EM acquires related information about virtual resources after the VNF is scaled up/down; and the EM sets a new performance monitoring threshold for the VNF according to the threshold policy and the related information about virtual resources after the VNF is scaled up/down, and the performance monitoring threshold includes at least one of a scale up/down threshold and a performance warning threshold.

A software defined networking (SDN)-based distributed denial of service (DDoS) attack prevention method, an apparatus, and a system, where a controller delivers a traffic statistics collection instruction to a first packet forwarding device. The traffic statistics collection instruction instructs the first packet forwarding device to perform traffic statistics collection, and carries a destination Internet Protocol (IP) address. The controller collects statistical data reported by the first packet forwarding device, obtains, according to the statistical data, a statistical value of global traffic flowing to the destination IP address, and delivers a DDoS prevention policy to a second packet forwarding device based on a determining result that the statistical value of the global traffic exceeds the preset threshold. Correspondingly, the second packet forwarding device receives the DDoS prevention policy from the controller, and performs, according to the DDoS prevention policy, prevention process on the traffic flowing to the destination IP address.

An example method of detecting device malfunctions at a subject device includes: obtaining a device event indicator representing an event detected at a device sensor of the subject device; obtaining an external event indicator representing an external event detected by an environmental sensor, the external event occurring external to the subject device; and identifying a device malfunction at the subject device based on the device event indicator and the external event indicator.

Wireless communications are described. A wireless device may be configured to transmit a first signal via a first cell group that may overlap in time with a second signal via a second cell group. The wireless device may adjust a signal transmission power of at least one of the first signal or the second signal. Additionally or alternatively, the wireless device may drop at least one of the first signal or the second signal. Adjusting and/or dropping at least one of the first signal or the second signal may be based on the overlap in time of these signals satisfying a duration threshold and a total power to transmit the first signal and the second signal exceeding a power threshold.

A communication device may be configured to access a plurality of subscriptions for a plurality of providers. For example, a communication device may be configured with at least one subscriber identity module (SIM). For a communication device having a plurality of subscriptions accessible thereto, the selection of a subscription to connect to a destination network may be configurable. The selection of a subscription from a plurality of available subscriptions may be based on a cost (e.g., financial cost, data cost, or another resource) associated with connecting to a destination network using different subscriptions. For example, a first subscription may be selected if connection to the destination network is more expensive using a second subscription and/or if the balance on the second subscription is too low.

Techniques for modifying data packet transmission characteristics by an intermediate node in a network are disclosed. An intermediate node in a data transmission network determines a current estimated transmission time for packets being transmitted from the source node to the intermediate node. The node analyzes a data packet to determine a Quality of Service (QoS) requirement for transmission of the first data packet. Based on the current estimated transmission time for packets being transmitted from the source node to the intermediate node and the QoS requirement for transmission of the first data packet, the intermediate node selects one or more transmission characteristics for forwarding the first data packet toward the destination node. The intermediate node transmits the packet toward the destination node in accordance with the one or more transmission characteristics.

Disclosed herein are system, method, and apparatus for account inheritance. The method performed at an application server includes receiving, via an application programming interface (API), data information received by each authorization gateway of a plurality of authorization gateways. The method includes performing calculation of an overall health of each authorization gateway of the plurality of authorization gateways based on a predetermined value of a weight assigned to each server of the plurality of servers and the value of service level corresponding to each server of the plurality of servers. The method includes balancing load of each authorization gateway of the plurality of authorization gateways by routing at least one client request message to a set of one or more authorization gateways of the plurality of authorization gateways based on the calculated overall health of each authorization gateway of the plurality of authorization gateways that is above a specific threshold value.

A method, an apparatus, an electronic device and a computer readable storage medium for adjusting an instance number are provided. The method includes: acquiring an actual performance index of a current time window; determining a theoretical instance number corresponding to the actual performance index; and in response to the theoretical instance number being greater than an instance creating upper limit of a current edge computing node, requesting another edge computing node having an instance addition capability to jointly create an instance of a total number equal to the theoretical instance number.
