Effective Event-Driven Group Communications in Wireless Tactical Edge Networks
Abstract
This paper provides an overview of design and research results relating to the use of NACK-Oriented Reliable Multicast (NORM) transport within the Zero Message Queue (ZMQ) message bus framework. We outline numerous new NORM modes and options implemented as ZMQ socket options to provide for use of NORM-based ZMQ messaging across a wide variety of scenarios, use cases, and applications. These improvements have been accepted back into the ZMQ source code for use and experimentation. The presented network emulation experiments show that reliable multicast transport improvements and overhead reduction can result from proper configuration of NORM as a reliable ZMQ message-delivery service in wireless networks. NORM ZMQs fixed-rate operation was shown to offer significant benefits over default congestion control when used in combination with more modern network traffic-management approaches. NORM ZMQ interoperability with modern queueing disciplines is also demonstrated, and areas for future improvement are discussed.
