摘要： A snapshot mechanism of a data processing system is provided herein. The snapshot mechanism includes providing a snapshot storage unit for storing the data created when snapshotting the target storage units and generating a plurality of snapshot images accordingly. Two different types of address tables in the snapshot image are used for corresponding to the storage units of the snapshot storage unit and the target storage units. The status of the target storage units can be recovered to the status at a predetermined time ago according to the snapshot images. The two types of address tables are respectively used for storing the data created by the data processing system and history data so as to prevent the data stored in the target storage units to be overwritten.

摘要： The present invention discloses a multi-priority media access control method for a multi-channel slotted ring network. In the slotted ring networks, each node has one tunable transmitter and one fixed receiver for data channels, and is able to inspect slot status on all channels. The header slot format defines the slot priorities on ring networks and limits which packets can be transmitted through the slots. By assigning slot priority based on two thresholds to raise and lower slot priority, multiple priority packets can be transmitted.

摘要： In a method and system for calculating CRC, a Partial CRC is first calculated directly according to a segment of a message. Then, a First Code including the Partial CRC appended with a plurality of zero-bytes is generated. Finally, the Adjusted CRC is calculated according to the First Code. Therefore, an Adjusted CRC can be derived directly from each segment of a message. After all segments of a message are received, all the derived Adjusted CRCs are merged to obtain a Final CRC of the message. The method and system can be quickly prototyped and implemented to various systems due to its simplicity.

摘要： A method and system for recognizing offloaded packets, wherein a common attribute of connection identifications among a plurality of offloaded connections is first calculated. Then, a connection identification of a packet is recognized to determine whether the connection identification of the packet has the common attribute so as to determine whether the packet is a non-offloaded packet. Therefore, the non-offloaded packet can be promptly recognized to greatly lower the recognition workload of an embedded processor, to improve the efficiency of executing a partial offloaded process by the embedded processor and to decrease the operation delay of the non-offloaded packet in a protocol offload processing system.

摘要： A storage structure and method having multiple protocol processor units are disclosed. The storage structure comprises a host CPU, a main memory, a storage device, a switch fabric, and a host bus adapter module. The host bus adapter module includes a plurality of protocol processor nodes for processing frames received from a network, and storing those frames into the storage device. A processing module of the host bus adapter module extracts the session information of each frame and compares it with entries recorded in a look-up table. If the connection information hits one entry of the look-up table, the frame can be bypassed into a corresponding protocol processor node according to the definition of the look-up table. Otherwise, a new entry will be inserted into the look-up table for designating a corresponding protocol processor node.
