一种面向内容中心的智能光网络内容缓存机制的设计与评估

With the increasing demand for access to rich content with multi-end devices, information sharing becomes the prior object for inter-connection. In this paper, we present a new approach to realize content-centric on top of existed network structure. We propose an on-path optical CDN mechanism based on today's Intelligence Optical Network (ION). We define an on-path optical content delivery network mid-node and design architecture to extend the scheme of ION with such on-path optical mid-node. We have also evaluated the performance of this mechanism through simulation. The results show that the network latency is significantly reduced in a massive-requests scenario regardless of the network scale.
