摘要： A system and method of transmitting data frames between a plurality of input ports to a plurality of output ports is described. The input ports segment portions of the received data frames to provide smaller data cells which are individually transmitted to an output port associated with a destination of the segmented data frame. Based upon information provided in the data cells received at the output port, the output port determines the ordinal positions of the received data cells within the segmented data frame and reassembles the data frame which was segmented at the input port. The output port then forwards the reassembled frame toward the associated destination.

摘要： A sequence number is used to indicate where a payload of a voice data packet should fit in a data stream and a technique is described for retrieving the sequence number for redundant payloads. A receiver maintains a history of previously received timestamps and sequence numbers for previous payloads. A received packet is unpacked to obtain a primary payload and its associated sequence number and timestamp, and a redundant payload and its associated timestamp offset. The primary payload sequence number and timestamp are stored in the history. A time-span of the data stream covered by the packet is found using the timestamp offset, and a portion of the history selected based on the time-span. A timestamp parameter for the redundant payload is calculated using the primary payload timestamp and the timestamp offset, and is compared to timestamps in the selected portion of the history to derive the redundant payload sequence number. The history is updated to include the timestamp parameter and sequence number of the redundant payload.
摘要翻译：序列号用于指示语音数据分组的有效载荷应适合于数据流的位置，并且描述了用于检索用于冗余有效载荷的序列号的技术。接收机维护先前接收到的时间戳和序列号的历史，以用于先前的有效载荷。接收的分组被解包以获得主要有效载荷及其相关联的序列号和时间戳以及冗余有效载荷及其相关联的时间戳偏移量。主要有效载荷序列号和时间戳存储在历史记录中。使用时间戳偏移和基于时间跨度选择的历史的一部分来发现分组覆盖的数据流的时间跨度。使用主有效载荷时间戳和时间戳偏移来计算冗余有效载荷的时间戳参数，并将其与所选历史部分中的时间戳进行比较以导出冗余有效载荷序列号。更新历史以包括冗余有效载荷的时间戳参数和序列号。

摘要： The specification discloses methods and apparatus for selecting the better of two or more copies of a cell in a cell-oriented redundant switching system connected to an external communications network. In the preferred embodiment, the best cell copy selection aligns redundantly transmitted cell streams before selecting cells for insertion in the data stream. Because the streams are aligned before the selection is made, the best cell copy selector compares each cell at the same instant in time, rather than basing its selection on past events.

摘要： An ATM switch includes a first stage, a second stage and a third stage each of which stages includes at least one basic switch, wherein the first stage, the second stage and the third stage are connected. The basic switch includes a part which refers to time information written in a header of an input cell and switches cells to an output port in an ascending order of the time information. In addition, the ATM switch includes a cell distribution part in the basic switch of the first stage. The cell distribution part determines a routes of a cell to be transferred such that loads of routes within the ATM switch are balanced. The ATM switch further includes an adding part which adds arriving time information to an arriving cell as the time information.

摘要： A packet switching system capable of ensuring the sequence and continuity of packets and further compensating for delays in transmission is disclosed. Each of two redundant switch sections has a high-priority queue and a low-priority queue for each of output ports. A high-priority output selector selects one of two high-priority queues corresponding to respective ones of the two switch sections to store an output of the selected one into a high-priority output queue. A low-priority output selector selects one of two low-priority queues corresponding to respective ones of the two switch sections to store an output of the selected one into a low-priority output queue. The high-priority and low-priority output selectors are controlled depending on a system switching signal and a packet storing status of each of the high-priority and low-priority queues.
