Resilient Brokerless Publish-Subscribe over NDN

Abstract

Publish-subscribe (pub/sub) is a popular API used by today's distributed multiparty applications. TCP/IP, however, does not directly support multiparty communication, therefore realizing pub/sub requires complex logic at the application layer. In this paper, we introduce SVS-PS, a brokerless pub/sub protocol running over NDN. SVS-PS utilizes NDN for data-centric security and many-to-many communication. Compared to IP-based implementations, SVS-PS enables publishers and subscribers to rendezvous “in the air”, thereby reduces the complexity of the application layer and lowers network traffic load. Our open-source implementation of SVS-PS makes NDN's networking primitives transparent to applications, allowing developers to work with a familiar pub/sub API while benefiting from NDN's secure and resilient multiparty communication support.
