A wired/wireless composite communication system and a wired/wireless composite communication method perform control to use wired communication for communication data having high priority and to use wireless communication for communication data having low priority among the types of communication data transmitted and received between communication devices provided within a vehicle. Specifically, the wired/wireless composite communication system and the wired/wireless composite communication method transmit wired communication data and wireless communication data divided on the basis of the priority set for each type of the communication data separately by wired communication and wireless communication, and couple the wired communication data and the wireless communication data separately received on a reception side to each other to reconstruct the communication data.

Transport packets comprising Universal Serial Bus (USB) packet data are transported over a communications network in a manner adapted to the USB context of the USB data transfers the USB packet data belongs to. A transport packet comprising USB packet data has assigned thereto at least one quality-of-service parameter value that depends on the USB context of the USB data transfer applicable to the USB packet data. A USB-data source device is configured to run a computer program causing it to expose the respective USB contexts of the USB data transfers applicable to USB packet data of the transport packets it outputs. The USB-data source device (or its sink) may inform the network of the relationship between transport packets and USB contexts of USB data transfers. The network may include a node device which discriminates the USB contexts of the USB data transfers applicable to USB packet data in transport packets and maps the transport packets to quality-of-service parameter values based on the discriminated USB contexts.

A wireless communication device may detect, within a specified time duration, at least a specified number of occurrences of a sequence of events, which includes the wireless communication device transitioning from a second cellular network operating according to a second radio access technology (RAT) to a first cellular network operating according to a first RAT, the wireless communication device failing to remain on the first cellular network for more than a specified time duration, and the wireless communication device returning from the first cellular network to the second cellular network. At least in response to this detection, the wireless communication device may determine whether to attempt future transition to the first cellular network while operating in the second network, based on one or more conditions, and/or may adjust one or more parameters used by the wireless communication device to determine when to redirect from the second cellular network to the first cellular network.

A method and system is described for delivering data streams in a network comprising devices connected to the network via adapters and wherein at least some of the devices are programmed to indicate priority of a data stream using priority parameter values of respective priority parameter types. One device in the network operates as a controller and the accompanying controller adapter is configured to perform priority enforcement on data streams according to all priority parameter types used within the datastreams in the network. A controller is also described and the controller can be a gateway configured to allow data streams into and out of the network. The method, system and controller find particular application in networks based on shared network segments, for example power line communication or networks based on coaxial cable.

An apparatus and a method are provided by which a packet is received, a service identification in the packet is detected, it is decided based on the detected service identification whether a tunnel protocol extension header is to be generated or not, and, when the tunnel protocol extension header is to be generated, the tunnel protocol extension header is generated, the received packet is encapsulated with the generated tunnel protocol extension header and the encapsulated packet is forwarded.

Embodiments of the present invention include systems and methods for providing Quality of service to RFID. In one embodiment the present invention includes a method of providing quality of service in an RFID network comprising storing RFID priority information corresponding to the RFID network, wherein the RFID network comprises one or more tags and one or more readers mapping the RFID priority information into priority information corresponding to a second network.

Packet network node and method of operating packet network node. Conventional packet network nodes react to congestion in packet network by dropping packets in a manner which is perceived by users to be indiscriminate. In the described system, indiscriminate packet discards are prevented by causing packets to be discarded on lower priority flows and flow aggregates. Further action is taken to reduce the likelihood of packet discards through: (1) classification of flows that are not observable at the point in the network where flow-based packet discards are deployed, but are consuming bandwidth and signaling classification information to flow-based packet discard function or a flow-based monitoring function or network management function; (2) classification of flows making use of extended monitoring functions that are not co-located with a flow-based packet discard function, where extended monitoring functions may perform monitoring of a flow or a group of flows over a period of time.

The disclosed technology addresses the need in the art for a solution configured to prevent network retransmission timeouts. A system is configured to receive a data packet originating from a sender and forward the data packet to a receiver. The system receives, from the receiver, an acknowledgment message that corresponds to the data packet and holds the acknowledgment message in a buffer until a delay time period expires, wherein the delay time period is determined based on a log of acknowledgment times. When the delay time period expires, the system forwards the acknowledgement to the sender.

Technologies are generally described for determining a quality-of-service of mobile applications. In some examples, a process for determining a quality-of-service of a mobile application executing on a mobile device coupled to a network includes collecting, by a mobile monitoring application (MMA), network usage measurements associated with multiple network communication sessions from a first network communication layer, wherein the multiple network communication sessions are conducted via the network and are associated with the mobile device. The process may also include evaluating, by the MMA, the collected network usage measurements to determine application-specific usage data associated with the mobile application, and determining, by the MMA, the quality-of-service of the mobile application based on the application-specific usage data.
