Abstract	Information-centric networks are a new paradigm for addressing and accessing content on the Internet, with Content-Centric Networking (CCN) being one of the more popular candidate solutions. CCN de-couples content from the location it is hosted and allows for mobility of the node requesting the content. However, CCN's ability to handle the mobility of the content source are limited and so far little research has focused on how both endpoints would be able to be mobile. We focus on mobility of the content source, using network embeddings as a tool. Network embeddings have already been proposed for content addressing and mobility management in prior work. In this paper, we first show that previously designed embeddings lead to a highly unbalanced storage and traffic load: More than 90% of all stored references are mapped to one node, which is involved in more than 95% of all queries. We propose a modified embedding, Prefix-S embedding, and a topology-aware key assignment, which enable a uniform distribution of the storage load. The maximum traffic per node is also considerably reduced from more than 95% to 35%.
