The Research And Implementation Of Intelligent Caching Strategy In Future Information Network

ABSTRACT:With people’s increasing relying on the Internet for resources and information, the Internet is bearing increasing pressure. From the users’ perspective, users in one regions have a correlation concerning the time and space of network resource transmission. For example, when a user gets some data, other users in the same region may also want to get to the same data, which result in repeat transmission of the same data and waste of network bandwidth. In order to solve the above problems, network caching techniques have emerged. As people’s reorganization gradually switches from the host-based location (IP address) to Internet content, the importance of network caching has been highlighted. As a typical network architecture in Information-centric Network (ICN), Content Centric Networking (CCN) requires that each node caches the content which comes through. In CCN, the existing caching strategy is relatively rigid and can’t adapt to different users’needs dynamically and meet the requirements of high-performance caches in CCN.This paper analyzes the network caching technology in Information-centric Network and proposes a cache management scheme based on the classification mapping in CCN. In this paper, the cache management scheme enables routers to classify and manage the network traffic and regional users, making different network resources meet the needs of users in different regions better and supporting the work on Cache Mapping Table (CMT) based on content classification and user classification. The cache management manages the cache by creating cache policy management module based on CMT. This cache management system can improve resources utilization and optimize the users’ experience.Based on this cache management scheme, this paper proposes a wisdom cache system based on CCN, including Content Classification Module (CCM), User Classification Module (UCM), Cache Establishment Module (CEM), Cache Maintenance Module (CMM), Cache Decision Policy Module (CDPM) and Cache Replacement Policy Module(CRPM). CCM classifies content in the network by analyzing the data packets, CCM classifies users in the network by analyzing the data packets. CEM sets up the cache mapping structure between content classes and user classes through analysis of the results obtained from above two functional modules. CMM is responsible for maintaining established cache mapping structure. CDPM and CRPM manage the content in the network based on the cache mapping structure.
