Abstract: A method is provided in one example and includes receiving a plurality of packets; identifying whether a particular packet, of the plurality of packets, is part of a sequenced flow; identifying whether a particular sequence number of the particular packet is being received within a time window; identifying whether the particular packet was a next expected packet for a particular flow; and forwarding the particular packet to a next destination. In more particular embodiments, packet inspection is used to set one or more flags for identifying characteristics associated with the plurality of packets. Certain packets in non-sequenced flows are routed directly from an input interface to an output interface of a resequencer module using a flow-through packet path.

Abstract translation: 在一个示例中提供了一种方法，包括接收多个分组; 识别所述多​​个分组中的特定分组是否是顺序流的一部分; 识别在时间窗口内是否正在接收到特定分组的特定序列号; 识别特定分组是否是用于特定流的下一个预期分组; 并将特定分组转发到下一个目的地。 在更具体的实施例中，使用分组检查来设置用于识别与多个分组相关联的特征的一个或多个标志。 非排序流中的某些数据包使用流通分组路径从输入接口直接路由到重新排序器模块的输出接口。
