Geometric Routing on Flat Names for ICN

This paper presents Griffin, a scheme of geometric routing on flat names to conduct massive content distribution and retrieval. A tree-based metric space T is proposed according to the concept of hierarchical division of symbol space. In Griffin, the network topology is embedded into the T-space, and content names are mapped to the T-space. Content publication and retrieval are supported by geometric routing in the T-space. Different from previous embedding schemes, Griffin constructs the T-space according to the network topology before embedding. In contrast to prior name resolution schemes, Griffin operates directly on the network topology without establishing an overlay. The correctness of Griffin is proved by the greediness of geometric routing. The experiments by simulation demonstrate that Griffin is efficient and scalable.
