Abstract: Metadata may be embedded in a service chain header (SCH) appended to a packet that is forwarded over a service chain path. The metadata may include information that is used to process the packet at a downstream service function chain (SFC) entity on the service chain path.

Accordingly, a receiving communication device receiver that offers progress towards the sink can elect to forward the packet.

Abstract: A method is provided for exchanging data flows between two terminals, via a multipath link formed of a plurality of transmission channels at least one of the channels of which is a unidirectional channel. The method implements two interface modules operating in transmission mode or in reception mode, respectively.

In reception mode, it reassembles the received secondary data flows into a single data flow. The interface modules route the acknowledgement information of the data packets transiting via a unidirectional channel via the return path of a bidirectional channel.

Abstract: A method of STA-initiated uplink (UL) aggregation is proposed in a wireless communication system. Under the STA-initiated UL aggregation, an STA can gain access to the medium through contention and after winning the TXOP, it passes the TXOP ownership to its AP to allow it to trigger UL MU transmission. Thus, the AP has increased chance of utilizing the medium while maintains fairness to both legacy APs and STAs. In addition, once AP takes over ownership of the TXOP, if it detects idle secondary channels, it can enable UL aggregation over the idle secondary channels, thereby fully utilizing the entire system bandwidth.

Abstract: A gateway receives a message from a first terminal to establish a connection between the first terminal and a second terminal. The gateway sends a second message to the second terminal to offer a connection. After receiving the first message from the first terminal, the gateway receives subsequent third messages from the first terminal that identify candidates for assisting in the formation of the connection. The gateway saves information about these candidates. The gateway either uses such information for facilitating the formation of the connection or forwards that information to the second communication terminal after receiving an answer accepting the establishment of a connection from the second terminal and determining whether the second terminal has a WebRTC client.

Abstract: A data processing system includes a phantom queue for each of a plurality of output ports each associated with an output link for outputting data. The phantom queues receive/monitor traffic on the respective ports and/or the associated links such that the congestion or traffic volume on the output ports/links is able to be determined by a congestion mapper coupled with the phantom queues. Based on the determined congestion level on each of the ports/links, the congestion mapper selects one or more non or less congested ports/links as destination of one or more packets. A link selection logic element then processes the packets according to the selected path or multi-path thereby reducing congestion on the system.
