A computer software application running on a wireless communication device determines whether an application scenario is urgent or nonurgent, and determines whether the user state is interest, uninterested or absent. The application sends the application scenario and the user state to a wireless networking device. The wireless networking device determines the user roles of different wireless communication devices. It further adjusts priorities of data packets destined to the wireless communication device based on the application scenario, the user state and the user role when downlink to the wireless communication device is congested. The priority is decreased when the application scenario is unurgent, the user role is a listener, and the user state is uninterested or absent.

Example packet control methods and apparatus are described. One example method includes detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node. The network node reduces a scheduling priority of the packet in the packet flow and generates a congestion isolation message, where the congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to the upstream node to instruct the upstream node to reduce the scheduling priority of the packet in the packet flow.

An on-board network system includes at least one processor. Plural relay devices that temporarily retain received data and relay the retained data in descending order of relay priority levels include a first relay device. For each set of data retained at the first relay device, the processor measures a retention duration for which the data is retained without being relayed. Data whose measured retention duration exceeds a predetermined threshold is congested data. A second relay device is a different relay device from the first relay device among the plurality of relay devices, and is capable of relaying the congested data. The processor requests the second relay device to raise the relay priority level of the congested data.

Systems and methods for managing data usage of a cellular modem during DoS/DDoS attacks are provided. According to one embodiment, a network security device of a private network detects a DoS attack in network traffic going through the network security device and determines whether the DoS attack is being transmitted through a cellular modem of a cellular data network. The network security device reduces data usage of the cellular modem when the DoS attack is detected and the DoS attack being is transmitted through the cellular modem.

An information processing method executed by a processor included in a computer, the computer including a memory that stores a plurality of flow entries in each of which a packet condition for choosing a packet, a processing content corresponding to the packet, and a type of the processing content are associated with one another, the information processing method includes choosing, from the flow entries, one or more candidate flow entries respectively including a type different from the type included in a new flow entry, when storing the new flow entry; detecting, from among the one or more candidate flow entries, a competitive flow entry having the processing content different from that of the new flow entry based on the packet condition; and notifying another information processing device coupled to the information processing device of a result of the detecting.

A method, non-transitory computer readable medium and apparatus for changing a quality of service for data packets that are delivered over-the-top are disclosed. For example, the method includes a processor that identifies the data packets as video data packets that are delivered over-the-top in a communication network, changes the quality of service associated with the data packets from a best effort quality of service level to a higher priority quality of service level, monitors the data packets until no video data packet is identified in the data packets and changes the quality of service associated with the data packets back to the best effort quality of service level from the higher priority quality of service level.

Aspects of oversubscription monitoring are described. In one embodiment, oversubscription monitoring includes accumulating an amount of data that arrives at a network component over at least one epoch of time. Further, a core processing rate at which data can be processed by the network component is calculated. Based on the amount of data and the core processing rate, it is determined whether the network component is operating in an oversubscribed region of operation. In one embodiment, when the network component is operating in the oversubscribed region of operation, certain quality of service metrics are monitored. Using the monitored metrics, a network operation display object may be generated for identifying or troubleshooting network errors during an oversubscribed region of operation of the network component.

Systems and methods are provided for dynamically routing packets using multi-flow and multi-path multiplexing connections. A first computing device and second computing device communicate via a plurality of data flows, which may be routed across various network paths. Each flow is defined by a set of network addresses, a set of ports, and a protocol specification, such as UDP. The second device sends information to the first device regarding the various data flows. The first device may send probing packets to facilitate collecting data flow information. Information may include latency, packet loss, and other values. Based on the information received, the first device may select or prioritize data flows to mitigate congestion, and address performance criteria. The first device may also transmit information regarding selected data flows to other devices, allowing the other devices to utilize a selected data flow even if they lack multiplexing capability.

An information handling system includes a plurality of memories and a plurality of processors. Portions of the processors and the memories are allocated as a virtual machine to a second information handling system. During a learning phase, a first processor to monitors a high bandwidth network activity of the second information handling system, and stores an event associated with the high bandwidth network activity. During an operating phase, the first processor detects the event, and transfers data associated with the high bandwidth network activity as a background activity based on available bandwidth between the information handling system and the second information handling system.

A quality of service (QoS) management system and guarantee is presented. The QoS management system can be used for end to end data. More specifically, and without limitation, the invention relates to the management of traffic and priorities in a queue and relates to grouping transactions in a queue providing solutions to queue starvation and transmission latency.
