The invention discloses a network slice deployment method and device of a mobile communication system. The method comprises the following steps: mapping an underlying infrastructure network to an underlying network layer in a complex multi-layer network model, and respectively mapping various network slices to various network layers on the underlying network layer; and deploying the network slicesbased on the theory of the complex multilayer network model. Through the application of the method disclosed by the invention, the resource can be managed more precisely and flexibly in the network slice deployment process of the mobile communication system so as to improve the utilization ratio of the network resource, the resource competition is avoided to the greatest extent, and the network communication quality is guaranteed.

The invention provides a system and a method for avoiding resource competition during starting a diskless workstation. The method comprises the following steps of sending a broadcast packet containing an Internet protocol address of the diskless workstation to a server so as to establish communication connection; downloading a guide program, a kernel, a mirror document and a configuration document of an operation system from the server to a memory of the diskless workstation; executing the guide program, and starting the kernel according to the configuration document and the mirror document; creating a temporary document directory during starting the kernel and realizing the operation that mounting the document system of the operation system to the diskless workstation; and creating a subdirectory under the created temporary document directory for storing the information generated in the starting process of the operation system, and creating a record document under the created subdirectory for recording the information generated in the starting process of the operation system. With the adoption of the method provided by the invention, the resource competition due to synchronous starting of multiple diskless workstations can be avoided, and the starting time of the diskless workstation can also be shortened.

The invention discloses a monitoring device for a server cluster. The device comprises a control node, wherein the control node comprises at least one task allocation node; each task allocation node comprises at least one acquiring node; each task allocation node is used for allocating a plurality of servers to be acquired to each acquiring node in the at least one acquiring node; and each acquiring node is used for acquiring the running state information of a server from the plurality of servers to be acquired, and forwarding the running state information of the server to the control node for saving through the belonging task allocation node. According to the monitoring device, each acquiring node is responsible for acquiring the information of the plurality of servers, a relation of one point to multiple points exists between each node and each server, and the plurality of acquiring nodes are not required to communicate with one another. Along with the expansion in the scale of the server luster, monitoring of a large-scale server luster can be realized only by increasing the quantity of the acquiring nodes or the quantity of business allocation nodes.

A method and a system for managing applications are provided. Further, the method includes: deploying an application container engine in an edge node; receiving, by the edge node, application deployment information sent by a central node; according to the application deployment information, downloading, by the edge node, an image containing a corresponding application from the central node; calling, by the edge node, the application container engine to load the image, and running, by the edge node, the application in the application container engine; and allocating, by the edge node, available resources for the application container engine.

The invention provides a shared data updating device. The device comprises a storage unit, a discrepant data computing unit, a data persistence unit and a data verification unit, wherein the storage unit is used for saving a basic data base table and a cache data base table; the basic data base table is used for saving summarized data of shared data; the cache data base table is used for saving discrepant data of the shared data; the discrepant data calculating unit is used for computing discrepant data of the shared data caused by updating operation; the data persistence unit adopts isolated transaction to insert the discrepant data into the cache data base table; and the data verification unit is used for inquiring the discrepant data of the basic data base table and the cache data base table and determining whether to submit isolated transaction according to a verification result. The invention further provides a shared data updating method. According to the technical scheme, locking process can be eliminated during data updating and verification processes on the basis that the data updating correctness is guaranteed, so that the concurrency supported by a system is improved.

The present invention provides a blockchain cross-chain operation method and a blockchain management system, including: obtaining the resource lock operation, original operation and inverse operation of each blockchain provided by each institution participating in the cross-chain operation, and first executing Each resource lock operation locks the resources required by each organization participating in the cross-chain operation; then executes each original operation in turn according to the execution order of each original operation in the cross-chain operation, and judges whether the cross-chain operation is satisfied during the execution process If the failure condition is not satisfied, after all the original operations are executed, execute the unlock operation to release the locked resource; if it is satisfied, perform the inverse operation corresponding to the original operation that has been executed, and execute the unlock operation to release the locked resource, to "restore" consumed resources. Based on the present invention, each organization participating in the cross-chain operation can realize the cross-chain operation while maintaining the original blockchain system, which enhances the practicability of the present invention.
