A METHOD AND A SYSTEM OF DOUBLE ENGINES SHARING MEMORY

摘要

The present invention discloses a communication mechanism of the main control boards which is separated from specific service and constructed on normal CompactPCI bus with the peripheral single boards, which particularly satisfies the communication mechanism of high performance and high reliability required in the communication devices, the communication mechanism completes the switch between the main control boards and peripheral single boards, and between the peripheral single boards, in which the core module is high speed sharing memory engine, in the main control boards which are mutually standby, there have respectively a high speed sharing memory engine, and both the high speed sharing memory engine are hot standby mutually. when one engine fails to work or the main control board which the engine resides fails to work, -another engine takes the work without gap, and any data information won't lost.
