Abstract: A first apparatus receives, at a first transmission rate, packets belonging to a target packet flow on which packet-shaping processing for controlling network traffic is to be performed, and stores the received packets in a first packet buffer. Then, the first apparatus performs first packet-shaping processing on the target packet flow by transmitting, at a second transmission rate, packets that belong to the target packet flow and read out from the first packet buffer. A second apparatus stores packets received from the first apparatus in a second packet buffer. When a shortage of buffer resource for storing packets belonging to the target packet flow occurs in the first packet buffer, the second apparatus performs second packet-shaping processing on the target packet flow by transmitting, at a third transmission rate, packets that belong to the target packet flow and are read out from the second packet buffer.

Abstract: A mobile station-side acquirer acquires the MTU value notified by a base station-side notifier and stores the acquired MTU value in a mobile station-side memory. A mobile station-side transmitter transmits data to a destination with the data size set to be smaller than or equal to the MTU value stored in the mobile station-side memory. A base station-side acquirer acquires the MTU value of the transmission path and stores the acquired MTU value in a base station-side memory. The base station-side notifier notifies the mobile station of the MTU value stored in the base station-side memory.

Abstract: A method and apparatus for implementing output queue-based flow control is provided. The method includes: implementing queue scheduling and flow control by using an output port-based cell queue and by counting the number of cells from different angles. In this system, the flow control and queue management are performed separately. The queue management is directly applied to the cell scheduling. The flow control does not directly depend on the cell statistical results in the queue management. Instead, it is implemented on the basis of the cell statistical results that are obtained according to the cell priority, output port and source chip number of the cells. Therefore, the provided method and apparatus may reduce and simplify the number of queues to be scheduled and implement fine and flexible back pressure control.

Abstract: Methods and apparatus for reducing data transmission. In one embodiment, rather than immediately transmitting first data, a first device postpones opening a data connection; any subsequently arriving data is queued with the first data, and transmitted together. Connection overhead is optimized by delaying connection establishment until it is necessary, and in some cases eliminating idle mode operation altogether. Stochastic embodiments are also disclosed for adjusting transmission behavior to maximize one or more desirable outcomes. For example, one such embodiment queues data for a stochastically determined period of time, prior to opening a data connection. The stochastically determined time interval balances the likelihood of efficiently servicing successively arriving data, and overall performance. Mechanisms for receiving and utilizing device user and/or receiver (e.g., base station) feedback are also disclosed.

Abstract: A network has a plurality of edge nodes (7a, 7b, 7c, 7d) and core nodes (3a, 3b, 3c) for carrying flows of data from an ingress gateway (7a, 7b, 7c, 7d) to an egress gateway (7a, 7b, 7c, 7d) along a path of core nodes. For any given path in the network work from an ingress node to an egress node, the number of flows is controlled. When network congestion occurs, the egress gateway (7a, 7b, 7c, 7d) provides an indication of the level of network congestion. Terminating flows is disruptive and therefore the ingress gateway (7a, 7b, 7c, 7d) can mark other flows with a congestion marker and send them to the egress gateway (7a, 7b, 7c, 7d). These marked flows are routed by the core and egress gateway (7a, 7b, 7c, 7d) but ignored for calculating network congestion. When the network congestion is alleviated, the marked flows can be un-marked and treated as normal flows, hence the network avoids unnecessary flow termination.

Abstract translation: 网络具有多个边缘节点（7a，7b，7c，7d）和用于承载来自入口网关（7a，7b，7c，7d）到出口网关的数据流的核心节点（3a，3b，3c） 7a，7b，7c，7d）。 对于从入口节点到出口节点的网络中的任何给定路径工作，流量的数量都受到控制。 当发生网络拥塞时，出口网关（7a，7b，7c，7d）提供网络拥塞级别的指示。 终端流是破坏性的，因此入口网关（7a，7b，7c，7d）可以用拥塞标记标记其他流，并将它们发送到出口网关（7a，7b，7c，7d）。 这些标记的流由核心和出口网关（7a，7b，7c，7d）路由，但被忽略以计算网络拥塞。 当网络拥塞得到缓解时，标记的流量可以被标记为正常流量，因此网络避免了不必要的流量终止。
