VectorSync

Abstract

Distributed dataset synchronization (sync for short) provides an important abstraction for multi-party data-centric communication in the Named Data Networking (NDN) architecture. Since the beginning of the NDN project, several sync protocols have been developed, each made its own design choices that cause inefficiency under various conditions. Furthermore, none of them provides group membership management, making it difficult to remove departed nodes from the protocol state maintained at each node. This poster presents VectorSync, a new NDN sync protocol that is built upon the lessons learned so far, provides group membership management, and improves the efficiency of dataset synchronization.
