In order to reduce energy consumption when tasks offloading and resource allocation in resource-constrained mobile edge computing scenarios, a cache-assisted dynamic offload decision-making and resource allocation joint optimization strategy for multidimensional resources including computing, communication, and caching resources was proposed. The caching service was formulated according to the popularity of the task, the communication resource allocation was optimized by controlling the transmission power of the user equipment, and the computing resources of the server were reasonably utilized in combination with the computing offload. A balanced optimization goal of minimizing delay and energy consumption was proposed, and an optimization algorithm based on deep reinforcement learning was designed. Finally, the effectiveness of this strategy was verified by simulation experiments. The results show that the strategy can exhibit better performance under the constraints of computing resources and cache capacity. [ABSTRACT FROM AUTHOR]

Information-Centric Networking(ICN) has become a hotspot in the research of next-generation network architecture. The typical feature of ICN is to use built-in cache to improve the propagation efficiency of content. With the increasing number of mobile users, future mobile users will also visit the ICN network, so the ICN network cache study under mobile scenarios is very meaningful. After introducing the ICN network, the scheme of mobility support caching is introduced, and then the traditional cache scheme and mobility cache scheme in ICN network are compared and summarized. Finally, the development and challenge of mobile cache scheme are prospected, for the follow-up study of mobile cache to provide a useful reference.

With the continuous development of the computer field, the stability of the system service is particularly important, and the cluster monitoring is essential. This article studies the design of a Linux cluster to detect the cluster service running state for the system performance monitoring manager. The monitoring manager uses C / S ( cdienl / server) mode, multi-thread technology is used to complete data acquisition and processing, cache technology to achieve data query and HTTP protocol, data transmission is then completed. Visual graphical interlace is designed to real-timely display system current status and history data. While a parameter is abnormal, manager can remote process bottlenecks to ensure the stability of system services. [ABSTRACT FROM AUTHOR]
