Abstract: A dynamic A-MSDU enabling method is disclosed. The method enables the recipient of an aggregate MAC service data unit (A-MSDU) under a block ACK agreement to reject the A-MSDU. The method thus distinguishes between A-MSDU outside of the block ACK agreement, which is mandatory, from A-MSDU under the block ACK agreement, which is optional. The method thus complies with the IEEE 802.11n specification while enabling the recipient to intelligently allocate memory during block ACK operations.

Abstract translation: 公开了一种动态A-MSDU使能方法。 该方法使得在块ACK协议下的聚合MAC服务数据单元（A-MSDU）的接收者能够拒绝A-MSDU。 因此，该方法区分来自块ACK协议下的来自A-MSDU的块ACK协议之外的A-MSDU，这是可选的。 该方法因此符合IEEE 802.11n规范，同时使得接收者在块ACK操作期间智能地分配存储器。

Abstract: A system includes an ingress node, an egress node, and one or more intermediate nodes. A path is formed from the ingress node to the egress node via the one or more intermediate nodes, where the path carries label distribution protocol (LDP) packets of an LDP traffic flow. One of the intermediate nodes detects traffic congestion, modifies one of the LDP packets to include an indicator of the traffic congestion, and sends the modified LDP packet towards the egress node. The egress node receives the modified LDP packet and notifies the ingress node of the traffic congestion in response to identifying the indicator of the traffic congestion within the modified LDP packet.

Abstract: Systems and methods are provided to enable a near-end receiver to control the far-end transmitter's data transmission such that the near-end receiver's TC data buffers do not overflow. In an embodiment, a high waterline and low waterline implemented into a near-end receiver are used to determine when the near-end receiver's TC data buffers are near maximum capacity. In an embodiment, the near-end receiver transmits a Packet Transfer Mode (PTM) All Idle Out Of Sync (AIOOS) codeword to the far-end transmitter when the high waterline is reached, and the near-end receiver stops transmitting the AIOOS codeword when the low waterline is reached.

Abstract: Providing quality of service (QoS) for applications such as Voice over IP (VoIP) and enforcing service level agreements (SLA) are major requirement in any current and future communication networks. On the other hand, more communication networks are employing adaptive transmission mechanisms, such as DVB-S2 ACM in satellite communication networks. In non-adaptive networks, QoS enforcers use static bit rate configurations. However, using a static bit rate configuration in an adaptive network may result in underflow situations, during which it may not be possible to utilize the full capacity of the transmission channel and expensive resources may therefore be wasted, In addition, using a static bit rate configuration in an adaptive network may result in overflow situations, during which it may be necessary to drop user traffic packets and therefore quality of service may not be maintained. It is therefore imperative that QoS enforcers have knowledge of the network's available bit rate at all times. This invention describes a method for achieving exactly that.

Abstract translation: 为诸如IP语音（VoIP）和执行服务级别协议（SLA）等应用提供服务质量（QoS）是当前和未来通信网络中的主要要求。 另一方面，更多的通信网络正在采用诸如卫星通信网络中的DVB-S2ACM的自适应传输机制。 在非自适应网络中，QoS执行器使用静态比特率配置。 然而，在自适应网络中使用静态比特率配置可能导致下溢情况，在此期间可能不可能利用传输信道的全部容量，因此可能浪费昂贵的资源。此外，使用静态比特率 在自适应网络中的配置可能导致溢出情况，在此期间可能需要丢弃用户业务分组，因此可能不维持服务质量。 因此，QoS执行者必须始终了解网络的可用比特率。 本发明描述了一种实现这一点的方法。

Abstract: Systems, modules, methods and computer readable mediums for adaptive removal of delay jitter and low end-to-end delay are provided. The method may include the following operations at a delay buffer: calculating a holding time for a plurality of packets input into a network; buffering each of the plurality of packets for the duration of the holding time; and arranging the buffered packets in a sequence indicative of an order in which the buffered packets were input into the network. The holding time may be based on a difference between a current maximum delay of the plurality of packets in a current time window and a delay of a first packet of the plurality of packets in the current time window. The method may also include playing back the buffered packets at a selected playback time. Playing back the buffered packets may be performed at a reception mechanism.

Abstract: A software and hardware system that provides for per flow guaranteed throughput and goodput for packet data flows using network transport protocols that have window-based flow control mechanisms or TCP-friendly flow control mechanisms. The system and method for guaranteed throughput of individual flows in turn enables a method for provisioning link bandwidth among multiple flows and provisioning network throughput and goodput at the granularity of individual flows. The invention also eliminates Layer 3 packet drops for a data flow using window-based flow control or TCP-friendly flow control, which in turn obviates congestion collapse and quality collapse scenarios.
