A Multi-Level DHT Routing Framework With Aggregation
Information-Centric Networking (ICN) has recently attracted research attention, which decouples content from hosts at the network layer, and retrieves a content object by its name (identifier), instead of its storage location (host IP address) in order to address IP network's limitations in supporting content distribution. However, ICN systems face scalability and efficiency challenges in global deployments. In this paper, the authors propose a scalable routing and name resolution framework, called Scalable Multi-level Virtual Distributed Hash Table (SMVDHT). SMVDHT uses a combination of name aggregation and multilevel virtual DHTs to achieve scalability.
