The invention discloses a distributed transaction processing method and system. The method includes: starting the outermost transaction, and assigning a unique outermost transaction ID; calling the RPC interface of the multi-service configuration service to allocate resources for different services, and The outer transaction ID is passed to the multi-service configuration service; the outer transaction ID is used as the parent transaction to nest multiple layers of new transaction IDs in turn, and the new transaction ID of each layer is the child transaction of the previous layer; from the parent transaction to the child transaction direction, in turn Perform resource allocation for multi-service configuration services, network element services, and basic services on each new transaction ID, and upload the corresponding service name and parent transaction ID; when all resource allocation operations in all transactions are successful, the user clicks on the GUI to submit the configuration , call Commit of the transaction manager to save the entire transaction. The invention ensures the final consistency of data, avoids the use of global locks, and greatly improves the concurrency efficiency of user operations.

The invention discloses a Java virtual machine realization method, which is characterized by the following: managing the integrated procedure in the Java virtual machine; switching the procedure dispatching; corresponding the procedure communication mechanism; controlling the internal memory to operate multiple Java procedures simultaneously; saving system resource; improving the procedure concurrent efficiency; reducing the dispatcher cost; fitting for inserted-type Java operation system.

The application aims to provide a cache management method and device. Compared with the prior art, the cache management device provided by the application queries and determines a target cache record matched with main key information in a cache containing a plurality of cache records, wherein each cache record comprises corresponding citation information and latest access information; and updating the citation information and the latest access information corresponding to the target cache record. The citation information and the latest access information are set in the cache records, so that the cache management device can be helped to set a replacement mechanism of the cache records; the cache management device ensures that the cache records active recently are stored in the cache, so that the active cache records are prevented from being replaced; and meanwhile, "the citation information" and "the latest access information" can be modified through only one atomic instruction without the need for performing a lock operation on the cache records, so that global lock contention during modification of an existing cache management algorithm is avoided and the concurrent efficiency is effectively improved.

The invention provides a synchronous method performing mutual exclusion access on shared resource, a device and network equipment. The invention accesses the shared resource by introducing shared resource pointer variable, establishes a copy of the shared resource when performing writing on the shared resource to be specially used for resource update, uses two locks to respectively protect the shared resource pointer variable and the shared resource copy, simplifies the introduction of complex shared resource into introduction of pointer variable, thus reducing the complexity of critical region operation, improving the system performance, ensures plural readers and one writer to access the shared resource simultaneously, achieving the effect of self sole occupation of data, and enhancing the system concurrency rate to a great degree.

The invention relates to the technical field of data storage, and provides a method, device and server for orderly controlling and storing information by lock-free threads. The method includes: according to the non-release state of the shared storage node in the circular queue, calling the CAS instruction during the period when the focus thread in the at least two first threads stores the current data in the shared storage node; The release state is changed to the release state, and the release state is used to indicate that the second thread can read the current data; the second thread is allocated a shared storage node in the release state; according to the storage position of the shared storage node in the circular queue and the original cursor in the CAS instruction Consistency, update the original cursor with a single vector, so that the focus thread locks the shared storage node. In this way, the threads can be controlled to access data in an orderly manner, which overcomes the additional overhead of controlling the storage queue and improves the thread concurrency efficiency.

The invention discloses a three-stage optimization method oriented to concurrent acquisition of energy consumption data, which is based on a large-scale energy sensing network, and adopts a plurality of energy nodes and an energy management network, wherein the energy management network comprises an energy main controller, a data acquisition terminal and a time processing system; the data acquisition terminal subdivides a data acquisition task DCJ into a plurality of sub-tasks; the time processing system establishes a time Petri network; the energy main controller proposes a three-stage optimization algorithm 3SOA based on a greedy algorithm and a genetic algorithm, so as to solve a dispatching problem of the DCJ; and the 3SOA comprises a first stage optimization, a second stage optimization and a third stage optimization. The three-stage optimization method adopts the 3SOA for solving the dispatching problem of the data acquisition task, obtains the minimal completion time of the DCJ, optimizes a dispatching scheme of the DCJ, can significantly shortens acquisition completion time by adopting the 3SOA, and improves concurrent efficiency; moreover, the application shows that the 3SOA can shorten a data acquisition cycle from 9.8 seconds to 6 seconds and increase the concurrent efficiency by 34.45%.

The invention discloses an ascending and descending parallel processing method under an RLC AM (radio link control acknowledged mode) in LTE (long-term evolution). An AMD PDU (AM data protocol data unit) is resequenced in an ascending receiving module, and the PDU is recombined into an RLC SDU (signal distribution unit) and is transmitted to a higher level; the recombined RLC PDU and a control structure relevant to the PDU are not deleted at first; when the RLC AM ascending module is awakened at the next time, the relevant RLC PDU and the control structure are deleted; when a state of a descending sending module is reported, only the control structure relevant to the PDU of VR (R)<=SN<VR (MS) is accessed. Therefore, the access time for a PDU receiving queue under a critical resource AM mode can be staggered, the particle size of a lock is reduced to the maximum extent, and the execution efficiency is improved.
