Abstract：How to efficiently utilize the temporary cached replicas poses challenges to the retrieval process of Content Centric Networking (CCN). Inspired by the idea of data fields, a hybrid routing scheme based on differentiated cache advertisement is proposed. In the scheme, depending on the content popularity and resident probability, the differentiated advertisement strategy is performed to choose the advertised content and calculate the attracting potential. When a retrieve is requested, in order to realize global routing and local response to the content request, the globally oriented potential field and locally attracting potential field are constructed for the stable original content source and volatile cached copies, respectively. The simulation results show that the scheme can decrease the request latency, increase the cache hit ratio, while improving the overall performance of content delivery with a small amount of additional overhead.
