    • A method for controlling a flow rate of multiple data flows at a network node on a path of the data flows includes the following steps. A private restriction token bucket (RTB) and a private guarantee token bucket (GTB) for each of the data flows and a shared token bucket (STB) common to all of the data flows are provided. n tokens are obtained from the RTBi for the data flow i when a message belonging to the data flow i arrives at the node and needs n tokens. An attempt is made to obtain n tokens from the GTBi for the data flow i and/or the STB. The message is transmitted if n tokens are obtained from the GTBi and/or from the STB, otherwise transmission of the message is delayed until n tokens are available in the GTBi and/or in the STB.
    • 用于控制数据流的路径上的网络节点处的多个数据流的流量的方法包括以下步骤。 提供了用于每个数据流的私有限制令牌桶(RTB)和专用保证令牌桶(GTB)以及所有数据流公用的共享令牌桶(STB)。 当属于数据流i的消息到达节点并需要n个令牌时,从数据流i的RTBi获得n个令牌。 尝试从数据流i和/或STB获得来自GTBi的n个令牌。 如果从GTBi和/或从STB获得n个令牌,则传送消息,否则消息的传输被延迟,直到在GTBi和/或STB中有n个令牌可用。

    • Embodiments of the invention relate to message queuing. In one embodiment, a request from an application for retrieving a message from a queue is received. The queue is stored across multiple nodes of a distributed storage system. A preference with respect to message order and message duplication associated with the queue is identified. A message sequence index associated with the queue is sampled based on the preference that has been identified. The message is selected in response to the sampling. The message that has been selected is made unavailable to other applications for a given interval of time, while maintaining the message in the queue. The message is sent to the application.
    • 本发明的实施例涉及消息队列。 在一个实施例中,接收来自应用程序的来自队列检索消息的请求。 队列存储在分布式存储系统的多个节点上。 识别与队列相关联的消息顺序和消息复制的偏好。 基于已经识别的偏好,对与队列相关联的消息序列索引进行采样。 选择该消息以响应采样。 已经选择的消息在给定的时间间隔内对其他应用程序不可用,同时将消息保留在队列中。 该消息被发送到应用程序。
