Research on Caching Strategy in Content Centric Network
Proceedings of 2017 the 7th International Workshop on Computer Science and Engineering · 2017
Content Centric Network (CCN) is a new kind of network architecture, which carried on routing, caching based on content.CCN fundamentally changed data package structure and addressing mode, from cared host address to focused on content itself.One of its main features is to leverage built in-network caching to improve the transmission efficiency of receiver-driven content retrieval and network resource utilization.CCN caching takes on several new characteristics: transparency, ubiquity, and fine granularity.However, these characteristics have made traditional caching theories, models and optimization techniques unable to be directly and seamlessly ported to CCN caching.In this paper, new features of CCN as well as their ensuing challenges are introduced, mechanisms of optimizing the performance of in-network caching are analyzed and compared from various angles.This paper summarizes and analyzes some key problems to be solved and the direction of future research.
