Disruption-resilient Publish and Subscribe

Noor Ahmed, Bharat Bhargava

Abstract

Publish and Subscribe (pub/sub) dissemination paradigm has emerged as a popular means of disseminating selective time-sensitive information. Through the use of event service or broker, published information is filtered to disseminate only to the subscribers interested in that information. Once a broker is compromised, information can be delivered unfiltered, dropped, delayed, perhaps colluding among the brokers in virtualized cloud platforms. Such disruptive behavior is known as Byzantine faults. We present a Disruption–Resilient Publish and Subscribe (DRPaS) system designed to withstand faults through continuously refreshing the virtual instances of the broker. DRPaS combines advances in cloud management software stack (i.e., OpenStack nova and neutron) to control the broker’s susceptibility window of disruption. Preliminary experimental results show that the defensive security solutions enabled by the underlying cloud computing fabric is simpler and more effective than the ones implemented at the application/protocol level to withstand disruptions.
