摘要： Media-aware and TCP-compatible bandwidth sharing may be provided. In various embodiments, a network node may periodically update a virtual congestion level for a transmission stream in a network. The transmission stream may comprise at least one video stream and at least one data stream. The network node may then calculate, based at least in part on the virtual congestion level, a random packet marking probability or a random packet drop probability. In turn, the network node may either drop or mark transmission packets according to the calculated marking and dropping probability. The network node may further calculate an optimal video transmission rate for the at least one video stream and adjust a video transmission rate for the at least one video stream accordingly. Rate-distortions parameters for the at least one video stream may influence the optimal video transmission rate calculation for the at least one video stream.

摘要： A method is provided in one example and can include receiving a source data stream, generating a base layer sub-stream from the source data stream, and generating an enhancement layer sub-stream from the source data stream. The method further includes communicating the base layer sub-stream to a client device using a first communication protocol, and communicating the enhancement layer sub-stream to the client device using a second communication protocol. In a particular example, the one-to-many communication protocol is a multicast communication protocol and the second communication protocol is a unicast communication protocol. In another example, the base layer sub-stream is sent to the client device via a first network connection and the enhancement layer sub-stream is sent to the client device via a second network connection.

摘要： Techniques for improving the performance of flow control mechanisms such as Pause are provided. The techniques provide for maintaining a fair distribution of available bandwidth while also allowing for fewer packet drops, and maximizing link utilization, in a distributed system. For example, in one embodiment, techniques are provided for achieving a fair share allocation of an egress port's bandwidth across a plurality of ingress ports contending for the same egress port.

摘要： The present invention provides improved methods and devices for managing network congestion. Preferred implementations of the invention allow congestion to be pushed from congestion points in the core of a network to reaction points, which may be edge devices, host devices or components thereof. Preferably, rate limiters shape individual flows of the reaction points that are causing congestion. Parameters of these rate limiters are preferably tuned based on feedback from congestion points, e.g., in the form of backward congestion notification (“BCN”) messages. In some implementations, such BCN messages include congestion change information and at least one instantaneous measure of congestion. The instantaneous measure(s) of congestion may be relative to a threshold of a particular queue and/or relative to a threshold of a buffer that includes a plurality of queues.

摘要： Various improvements are provided for prior art policing methods, including token bucket methods and virtual time policing methods. Some preferred methods of the invention involve assigning a non-zero drop probability even when the packet would otherwise have been transmitted according to a prior art policing method. For example, a non-zero drop probability may be assigned even when there are sufficient tokens in a token bucket to allow transmission of the packet. A non-zero drop probability may be assigned, for example, when a token bucket level is at or below a predetermined threshold or according to a rate at which a token bucket is being emptied. Some implementations involve treating a token bucket as a virtual queue wherein the number of free elements in the virtual queue is proportional to the number of remaining tokens in the token bucket. Such implementations may involve predicting a future virtual queue size according to a previous virtual queue size and using this predicted value to calculate a drop probability.
摘要翻译：为现有技术的管理方法提供了各种改进，包括令牌桶方法和虚拟时间监管方法。本发明的一些优选方法涉及分配非零丢弃概率，即使当根据现有技术的监管方法将分组以其他方式传输时也是如此。例如，即使在令牌桶中有足够的令牌来允许分组的传输，也可以分配非零丢弃概率。例如，当令牌桶级别等于或低于预定阈值时或者根据令牌桶被清空的速率时，可以分配非零丢弃概率。一些实现涉及将令牌桶视为虚拟队列，其中虚拟队列中的空闲元素的数量与令牌桶中剩余令牌的数量成正比。这样的实现可以涉及根据先前的虚拟队列大小预测未来的虚拟队列大小，并且使用该预测值来计算丢弃概率。

摘要： Class-based bandwidth partitioning of a sequence of packets of varying packet classes is performed, such as, but not limited to determining whether or not to admit a packet to a queue based on a probability corresponding to a class of packets associated with the packet, with this probability being based on measured arrival traffic and a fair share based on the length of the queue. Data path processing is performed on each packet to determine whether to admit or drop the packet, and to record the measured received traffic. Control path processing is periodically performed to update these probabilities based on determined arrival rates and fair shares for each class of packets. In this manner, a relatively small amount of processing and resources are required to partition bandwidth for a scalable number of classes of packets.
摘要翻译：执行不同分组类别的分组序列的基于类的带宽划分，例如但不限于基于与分组相关联的分组类别对应的概率来确定是否允许分组到队列，这个概率基于测量的到达流量和基于队列长度的公平共享。对每个数据包执行数据路径处理，以确定是否允许或丢弃数据包，并记录测量的接收流量。定期执行控制路径处理，以便根据每类分组的确定到达率和公平共享来更新这些概率。以这种方式，需要相对少量的处理和资源来分配用于可分级数量级的分组的带宽。
