摘要： A multi-stage switching network that can hitlessly reconfigure itself comprising a controller that controls each stage separately. The controller designates the paths through each stage according to the set of paths currently active. If the set of paths changes, the controller sends a new set of paths to the first stage while using the old set of paths for the second stage during a first frame. On the next frame, the controller causes both stages to use the new set of paths.

摘要： A method of the grooming traffic signals through a composite switch is disclosed that enables a traffic signal that is being transmitted between any two constituent switches to be re-routed through the composite switch without a hit (i.e., the dropping, replacing, inserting, or repeating of at least one bit in the traffic signal). This applies whether the constituent switches are adjacent in the composite switch or not. The composite switch in accordance with the illustrative embodiment comprises multiple routes between adjacent constituent switches and incorporates a mechanism that compensates for differential propagation delays along the routes. And still furthermore, the composite switch in accordance with the illustrative embodiment comprises alternative routes through different constituent switches and incorporates a mechanism that compensates for differential propagation delays through the constituent switches.
摘要翻译：公开了一种通过复合开关整理交通信号的方法，其使得能够在任何两个构成交换机之间传输的业务信号通过复合交换机重新路由而不受命中（即，丢弃，替换，插入或重复交通信号中的至少一个位）。这适用于组合开关是否在复合开关中相邻。根据说明性实施例的复合开关包括相邻组成开关之间的多个路线，并且包括补偿沿着路线的差分传播延迟的机构。此外，根据说明性实施例的复合开关包括通过不同构成开关的替代路线，并且包括补偿通过构成开关的差分传播延迟的机构。

摘要： A two-stage switching network that takes data from an input and first switches it through a space stage into a buffer. Data from the buffer is then switched in a time-space stage to an output. Each buffer, advantageously, holds one frame of data. Further, there are two buffers such that one may be filled from the input while the other is emptied to the output, and vice-versa. A maximum amount of data may be switched in space and time regardless of its origin and destination, effecting a switching network that is capable of the widest SONET-specified bandwidth.
摘要翻译：一个两级交换网络，从一个输入端接收数据，并首先将其通过一个空间级切换到一个缓冲区。然后将来自缓冲器的数据在时空阶段切换到输出。每个缓冲器有利地保持一帧数据。此外，存在两个缓冲器，使得可以从输入填充另一个缓冲器，而另一个缓冲器被排空到输出端，反之亦然。无论其来源和目的地如何，最大数量的数据可以在空间和时间上进行切换，从而实现能够达到最大SONET指定带宽的交换网络。
