摘要： An intermediate network node is configured to forward a plurality of packets concurrently, e.g., as a vector, rather than one packet at a time. As such, the node can load a single sequence of forwarding instructions that may be repeatedly executed for packets in the vector. In addition, the intermediate network node adaptively controls the rate at which it processes data packets through a directed forwarding graph. To that end, the intermediate node is configured to dynamically select the number of packets per vector, i.e., vector size, processed at each node of the forwarding graph. Further, the intermediate node also may be configured to dynamically select timing intervals for one or more “node timers” used to control the rate at which packets traverse through the graph. Illustratively, the vector size and node-timer intervals are selected so that the average latency through the forwarding graph is less than a predetermined target latency, e.g., 50 microseconds (μs).
摘要翻译：中间网络节点被配置为同时转发多个分组，例如作为向量，而不是一次一个分组。因此，节点可以加载可以对向量中的分组重复执行的单个转发指令序列。另外，中间网络节点通过定向转发图自适应地控制其处理数据分组的速率。为此，中间节点被配置为动态地选择在转发图的每个节点处处理的每个向量的分组数量，即向量大小。此外，中间节点还可以被配置为动态地选择用于控制分组穿过该图的速率的一个或多个“节点定时器”的定时间隔。示例性地，选择矢量大小和节点定时器间隔，使得通过转发图的平均等待时间小于预定的目标等待时间，例如50微秒（μs）。
