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 embodiment of the present application discloses a page access method. The method includes: judging whether the target page to be accessed is a historical page, and if so, obtaining the page resources and page data corresponding to the historical page stored when the historical page visit is ended; using the obtained historical page page resources and Page data access history page. The embodiment of the application also discloses a page access device. Through the technical solution of the embodiment of the present application, the access to the historical page can be realized while retaining the page state when the historical page access is completed, the concurrent pressure on the server is reduced, the access operation time is saved, and the page access efficiency is improved as a whole.
