The invention provides a resource data protection method and device. The protection method comprises the steps of S1, receiving an update request sent by any terminal, determining to-be-updated targetdata in resource data according to the update request, and setting the target data to be in a locking protection state, wherein the locking protection state is that other terminals are not readable and writeable, and other terminals are terminals except any terminal; and S2, exporting the target data to any terminal. According to the resource data protection method and device, the situation thatthe to-be-updated target data is refreshed again when any terminal occupies and updates the to-be-updated target data is avoided; and the probability of resource data conflicts during updating of thetarget data by any terminal is reduced.

The invention relates to a multi-channel collaboration multi-address access method and a system. The method comprises the following steps: a source node selects a data channel from a channel state table and sends a CRTS packet on a control channel; when a target node which receives the CRTS packet judges that the data channel is available, the target node sends a CCTS packet on the control channel; when a neighbor node judges that the data channel is available and meets the collaboration conditions; the neighbor node sends a HA packet on the control channel and sends an RTH packet as a collaborative node; when the source node and the target node receive the RTH packet on the control channel, the source node and the target node respectively send an SCA packet and a DCA packet on the control channel, and the source node sends the data packet to the target node through the collaborative node on the data channel; and the target node sends a busy tone after receiving the data packet. On the one hand, the invention can solve the technical defects of low transmission reliability and the like of the existing data transmission due to conflicts, on the other hand, the invention can greatly reduce the application complexity and the cost.

One method for managing data of data bank relates to storage item. Get corresponding Hash value by Hash function conversion with prescriptive time for key value of storage item and judge whether the key value is collision after Hash function conversion. Storage the item key value of collision into TCAM and the first RAM associated with TCAM. In the prescriptive time, the item after Hash function conversion without collision and its Hash value storage into the second RAM. There is a kind of system relates to storage unit, TCAM, first RAM and second RAM. The first RAM connects with the said TCAM. The item after Hash function conversion without collision storages into the second RAM and storages the conversion item into TCAM and first RAM. Through this system, it can carry in low cost and wastage.

The invention discloses an automatic address identification handshaking method of a share type bus in a master-slave communication mode. In the handshaking method, response data packets can be sequentially sent after each measuring control terminal receives a super command sent by a main control module by means of corresponding delayed duration determined according to an obtained modulus and the maximum delivery number of the measuring control terminals, which is required by a measuring control terminal delivery address for a shared bus, therefore a majority of measuring control terminals areguaranteed to normally report addresses to the main control module; and moreover, the probability of bus confliction is further reduced by adopting intercepting index avoidance algorithm delay and a bus monitoring method. When field installation is carried out on equipment adopting the share type bus in the master-slave communication mode, the method ensures that the operation steps of installation personnel are simplified, working efficiency is improved and address setting equipment is simultaneously saved.

The invention discloses a method for improving the acceleration performance of the hardware of a firewall chip. The method of the invention comprises the steps that: the exterior of the firewall chip is configured with an external memory, in which an area is respectively divided for a connecting index table and a connecting table, and the base addresses of the connecting index table and the connecting table are stored into the firewall chip and a CPU. The mirror images of the connecting index table and the connecting table are established in a CPU memory. The mirror images, and the connectingindex table and the connecting table in the external memory of the firewall chip are kept synchronizing. Then, the firewall chip and the CPU work collaboratively so as to realize the access and the establishment to the connecting index table and the connecting table. The method of the invention fundamentally solves the problem that the connecting list items of the existing speeding-up firewall ofthe hardware are too few and concurrent connections can not meet the requirement of the performance of the firewall. In addition, the enlarged connecting index table and the connecting table reduce the probability of the conflict of HASH algorithm and enhance the efficiency of processing the data packet of the firewall chip.

The invention discloses a routing method for a three-dimensional integrated circuit on-chip network. The optimal route of the node to ensure that the data packet reaches the destination node through the optimal route; the data routing step is used based on the principle of illegal steering between the layers of the horizontal device layer and the constraints of the corresponding steering restrictions in the vertical plane, and the routing strategy is used to transfer the data The packet is gradually routed from the source node to the destination node through the intermediate node. The invention also discloses a routing system of the three-dimensional integrated circuit on-chip network.
