An Application Layer Traffic Optimization (ALTO) node comprising a processor configured to import a first set of network information from one or more software defined networking (SDN) nodes, aggregate the network information received from the SDN nodes, calculate a plurality of traffic optimization decisions based on the aggregated network information, and forward the traffic optimization decisions to the SDN nodes. Also disclosed is a method for optimizing traffic using a SDN node and an Application Layer Traffic Optimization (ALTO) node, the method comprising receiving a request for network resources from a node, obtaining a plurality of traffic optimization information from the ALTO node, negotiating one or more paths with a second SDN node using the traffic optimization information received from the ALTO node, constructing the paths, and sending a response to the node that indicates the node may forward packets via one of the paths.

Frames received at a redundant port connecting a node to a communications network are identified by the frames including a sequence number associated with a source. A frame is received at the redundant port from a source. A newest sequence number of frames received from the source at the node is determined. A window of frames from the source is determined by corresponding sequence numbers. The window includes sequence numbers preceding the newest sequence number and associated with reception information of a corresponding frame at the node. The node relays the frame, when a sequence number of the received frame is within the window and the reception information indicates a first reception of the frame at the node.

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.

Provided is an apparatus to detect congestion of a network using a receiver of a communication system. The apparatus includes a transport layer information extraction unit configured to extract transmission control protocol frame information from information that is received from a lower layer. The apparatus also includes a congestion information filtering unit configured to identify and output a packet to determine congestion in the transmission control protocol frame information. The apparatus further includes a congestion detection unit configured to determine whether the network is congested using the packet to determine congestion. The apparatus includes a congestion information output unit configured to, upon detecting congestion in the network, deliver information indicating the detection of the congestion in the network to an operating system or other applications.

A system and a method for prioritizing network traffic using application awareness and network awareness in a network environment is disclosed. An exemplary method can include receiving a network traffic priority for network traffic associated with a job performed by a distributed application; and based on the network traffic priority, assigning the network traffic to a network classification model, such as an access control list, associated with a network element for directing the network traffic in a network. The network classification model is associated with a network traffic priority class having defined quality of service (QoS) features, such that the network traffic traverses the network according to the defined QoS features.

The invention introduces a method for an automatic scaling of data consumers, performed by a processing unit of a data-consumer server, which contains at least the following steps. State-update requests are received from data consumers, where each state-update request includes a busy state or an idle state and the busy state indicates that the data consumer reads data from a queue and processes the read data. A first quantity of data consumers, a second quantity of busy states and a third quantity of idle states are calculated. A fourth quantity of data consumers to be produced is estimated according to the first, second and third quantities. Data consumers of the fourth quantity are produced.

One or more wireless communication systems may coexist at about the same geographical location and be configured to access the same radio channel. The coexistence of these systems may cause collisions and degrade throughput. Although countermeasures, such as reserving airtime with a resource assignment, may be taken to avoid collisions, these countermeasures are degrading throughput as well. The reserved airtime is reduced by adding a start time to the resource assignment. The reduced airtime may be used by others for performing a transmission, thus increasing the throughput and efficiency of the access to the radio channel.

An information processing apparatus according to an embodiment of the present technology includes a determination unit and a delivery control unit. The determination unit determines, regarding each of a plurality of reproduction apparatuses, which becomes a target of streaming delivery of content by unicast via a wireless network, whether or not a communication state of the wireless network is normal. The delivery control unit excludes a communication failure apparatus that is a reproduction apparatus of the plurality of reproduction apparatuses, whose communication state is determined not to be normal, from the target of the streaming delivery by the unicast.

Communication apparatus includes multiple interfaces configured to be connected to respective links in a packet data network. Switching circuitry in the apparatus is coupled between the interfaces and is configured to receive, via a first interface among the multiple interfaces, an adaptive routing notification (ARN) requesting that a specified flow of packets from a given source to a given destination in the network be rerouted. The switching circuitry is configured, upon verifying that the first interface serves as an egress interface for the packets in the specified flow, to reroute the specified flow through a different, second interface among the multiple interfaces when there is an alternative route available in the network from the second interface to the given destination, and after finding that there is no alternative route available from any of the interfaces to the given destination, to forward the ARN to a plurality of the interfaces.

A first mobile device and a plurality of other mobile devices connect to a network. A routing configuration table is configured. The routing configuration table includes rules about sharing communication between the first mobile device and the plurality of other mobile devices. The first mobile device is paired with the plurality of other mobile device based on the routing configuration table. A determination is made whether the first mobile device has received a communication. In response to the determination that a communication has been received by the first mobile device, the communication is transferred to at least one mobile device of the plurality of mobile devices based on the configuration table.
