Research on Caching Strategy in Content Centric Network
Abstract— 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.
Index Terms— content centric network, in-network caching, transparency, fine granularity.
