摘要： A switching network for efficiently receiving and transmitting data packets having both frames and messages includes a crossbar switch with a plurality of surrounding ports for exclusively switching frames which normally consist of large data streams of 40 to 60 bytes. Then the ports are connected together in a message ring and small data entity messages, for example 4, 8, or 12 bytes, are switched from an input port to an output port around the ring avoiding congestion of the crossbar switch.

摘要： Biphase mark codes (BMC) are used in digital communications. Most BMC formats use preambles for rate determination and synchronization. A decoder compares the intervals of continuous high or continuous low voltages in a BMC stream to predetermined minimum and maximum values of half cell, full cell and one-and-a-half cell intervals for all supported sampling rates. If a pattern matching a preamble is found, the sampling rate is locked in and the decoder is synchronized to the BMC stream. Once locked, the decoder uses the predetermined minimum and maximum values at the locked rate to generate half cell, full cell and one-and-a-half cell indicators for a decoding state machine which decodes data in the BMC stream or decodes expected preambles.

摘要： A high data rate switch is disclosed. The switch may include fiber optic channels where a plurality of switching elements necessarily operate at a significantly lower data rate providing routing of variable or fixed size data packets from a plurality of source ports to a plurality of destination ports via a single serial link. This is may be provided by storing the high rate data temporarily in memory in each of the source ports and then downloading it at a lower rate in a complete data packet to a designated switching element, almost immediately distributing the next data packet that has been received by the source port to a next switching element. The switching element configuration provides automatic redundancy and a minimum amount of frame overhead while sustaining throughput at the high data rate.
