Abstract: A classification mechanism automatically aligns time-sensitive data streams to sequences (schedules), according to information in the packets or other information and classification criteria specified by a human network administrator, a sequence agent, an application program or otherwise. When a packet arrives at a first sequence-aware switch along a path, the packet is aligned to a new or existing sequence. When a new sequence is established, appointments are reserved at sequence-aware switches along the path. The packet is placed in a queue, based on its classification. When the packet reaches the head of the queue, at that queue'’ appointment time, the switch forwards the packet along the path. If possible, appointments have been reserved at subsequent switches along the packet’s path, so the packet can be forwarded through the subsequent switches without delay. Packets that do not match any classification criteria are handled on a best-effort basis.

Abstract translation: 分类机构（202）根据分组中的信息或由人网管理员，序列代理，应用程序或其他方式指定的其他信息和分类标准自动对准时间敏感数据流到序列（调度）。 当分组沿着路径到达第一序列感知交换机（212）时，分组与新的或现有的序列（208或214）对准。 当建立新的序列时，沿路径的顺序识别交换机保留约定。 基于其分类将分组放置在队列（208或214）中。 当数据包到达队列的头部时，在该队列的“约定时间”中，交换机沿路径转发数据包。 如果可能，沿着分组的路径在后续交换机（204或206）处保留约定，因此可以不延迟地通过后续交换机转发分组。
