摘要： A system for checking the integrity of data transfer in a switching element in a high speed packet switching network node where multicasting is performed by simultaneously shifting data from a first shift register into the targeted device shift registers. The outputs of the device registers are fed back into the first shift register. The checking system includes a device select circuit for selecting the targeted via a set of select lines and a negative OR gate circuit. The select line signals and the first register output are inputs to the OR gate, the output of which is fed back to the first register. A comparator circuit has inputs supplied by the device select lines and the outputs of the device registers. A processor compares the contents of the first register to the outputs from the logic comparator circuit to test whether the data has been properly multicast to the targeted.

摘要： A Switch Fabric system comprising at least one Switch Fabric subsystem (100, 200) further including a set of Switch cores elements (111, 112, 121, 122) that are mounted in a port expansion permitting attachment of at least a first and second sets of Protocol Adapters (1, 2) under a routing control process. A Primary Switch controller (PSC) has a complete knowledge of the topology of the switch, e.g., the number of subsystems, the nature of the port expansion etc., while each Secondary Switch Controller only has a limited knowledge of that topology. One particular Switch Core (111, 211) which has a full-duplex communication capability in each Subsystem is assigned the key function to interface communication between the PSC and the other SSC in a same Switch Fabric Subsystem.
