20100157800METHOD FOR PROCESSING NETWORK TRAFFIC LOADING BALANCE - A method for processing network traffic loading balance is adapted for balancing the load of a session of various data packet processing threads in a network equipment. The method includes the following steps. First, a plurality of data packet processing threads is executed, a queue is assigned to each thread for storing the received data packets, and the data packet is read from the queue by the thread for processing. Then, it is determined whether the number of the data packets in the queue satisfies a traffic threshold value. If the number of the data packets in a certain queue satisfies an operating threshold value, new data packets are allocated by the network equipment to other queues without affecting the integrity of the session. Therefore, the present method not only maintains the integrity of the session, but also ensures the uniformity in load among the data packet processing threads.06-24-2010

20090138656Method of skipping synchronization process for initialization of RAID1 device - A method for skipping an initialization process of synchronization of an RAID 1 device skips synchronization process of the RAID1 device through a bitmap technique. First, an RAID1 device is established, a space of the same size is divided from each member disk of the RAID1 device for storing a bitmap corresponding to each data block on each member disk. When a read/write operation is executed on the RAID1 device, before the bit value in the bitmap corresponding to the data block is read, whether the bitmap exists or not is determined first, then corresponding operation is executed according to the bit value in the bitmap corresponding to data block requesting the read/write operation. The method skips synchronization process of the RAID 1 device during the initial establishment, thereby largely saving the time required by the synchronization process for initialization, and further improving the overall performance of the RAID1 device.05-28-2009
