摘要： Optical interconnect fabrics and optical switches are disclosed. In one aspect, an optical interconnect fabric comprises one or more bundles of optical broadcast buses. Each optical broadcast bus is optically coupled at one end to a node and configured to transmit optical signals generated by the node. The optical fabric also includes a number of optical tap arrays distributed along each bundle of optical broadcast buses. Each optical tap array is configured to divert a portion of the optical power associated with the optical signals carried by a bundle of optical broadcast buses to one of the nodes.

摘要： Methods and systems are provided that prevent buffer overflow in multibus systems. In one aspect, a method for controlling the flow of data in a multibus system includes, for each node having an associated broadcast bus in the multibus system, generating status information regarding available data storage space of each receive buffer of the node. The method includes broadcasting the status information to the other nodes connected to the broadcast bus and collecting status information regarding the available storage space of receive buffers of the other nodes connected to the broadcast bus. The method also includes determining whether or not to send data from the node to at least one of the other nodes over the broadcast bus based on the collected status information.
