The invention discloses a directory distribution method and network architecture orienting to a high-concurrency retrieval system, and belongs to the field of computer network. The invention provides a retrieval method combining the integrated retrieval based on servers with the distributed retrieval based on directory distribution according to the behavior characteristics of video retrieval of users, and makes full use of the server capability of each user node to complete the update of the consistency in the directory file when the user node resource is free, so that the user can acquire data consistent with those on the retrieval server when retrieving. The user firstly searches for the required retrieval result by reading the local directory file when retrieving, and adopts the integrated retrieval based on the retrieval server when the directory file cannot meet the requirements of the user, thereby not only guaranteeing the retrieval response time and improving the user experience, but also guaranteeing the accuracy and integrity of the retrieval result. Under the pressure of high-load and high-concurrency retrieval access, the invention, which has high expandability, can obviously relieve the pressure of servers in a retrieval center, reduce the hardware input and reduce the system cost.

Embodiments of the present application provide a virtual machine snapshot processing method, device, and system. In the embodiment of this application, by adding a snapshot cache to the VM, the disk blocks whose frequency of use in the disk snapshot required during the VM startup process meets the set requirements are stored. Based on this, when the disk read request issued by the VM during the startup process is received , respectively query the disk block requested by the VM in the disk of the VM and the snapshot cache, and return to the VM when the disk block requested by the VM is found in the disk or snapshot cache of the VM. Since the snapshot cache stores the disk blocks whose frequency of use in the disk snapshot meets the set requirements, it can increase the probability that the read disk request hits the required disk block, reduce the probability of requesting the disk block from the snapshot center, and thus reduce the overall cost of the snapshot center. concurrent pressure.

The invention discloses an SOA-based service robot cloud platform interface system and method, including a service layer, an SOA interface layer and an application layer, wherein the service layer sends a service request to the SOA interface layer, and the SOA interface layer responds to the service request The service query and scheduling realizes service proxy and remote invocation. The application layer provides coarse-grained services based on the invocation of the SOA interface layer, and provides service feedback and log interfaces to the SOA interface layer. According to the development situation of the robot and the use characteristics of the current robot, the present invention takes into account the needs of mobile clients and robot developers in the design process of cloud computing, analyzes the requirements of the cloud computing platform, and follows the design principles of SOA, and implements the cloud computing The platform is designed so that the services of the robot and the cloud computing platform can be independent of each other.

The invention discloses a low-voltage household meter power failure alarm device and method based on edge computing. The alarm device includes a data acquisition device and an edge computing control device; wherein, the data acquisition device is used to collect the power failure issued by the low-voltage user electric energy meter after the power failure The event data is sent to the edge computing control device; the edge computing control device is used to perform local edge computing on the received power outage event data to obtain power outage fault type data and send it to the master station. The invention obtains the type of power outage and sends it to the main station by performing edge calculation of data locally, thereby reducing the concurrency pressure of the main station and avoiding downtime of the main station due to a large amount of concurrent data.

The invention discloses a request preprocessing method for real-time on-demand data broadcast system and capacity improvement.
