Publish/Subscribe Versus a Content-Based Approach for Information Dissemination
Abstract
NATO has identified the WS-Notification standard
from OASIS to support event-driven communication in the NATO
enterprise and when building coalition networks. Using this
standard promotes interoperability. However, there is significant
overhead associated with WS-Notification since it is built on
SOAP Web services (WS). Overhead can be problematic in
networks with scarce resources. In this paper we perform a smallscale
comparative evaluation of overhead of WS-Notification with
another publish/subscribe standard: Message Queuing Telemetry
Transport (MQTT). We also measure how these standards
compare to the novel approach of content-based networking
under the same networking conditions. We use the Named Data
Networking (NDN) flavor of content-based networking for our
experiment. Though fundamentally different, these approaches
can be used to realize the Service-Oriented Architecture (SOA)
paradigm.
The drawback of standard publish/subscribe approaches is
that they usually rely on a broker, which constitutes a single
point of failure. NDN, on the other hand, has no broker which
makes it interesting to consider for tactical networks. We use
NATO Friendly Force Information (NFFI), which is much used
for friendly force tracking, as the data format for the payload
in all our tests.
In the paper we focus on the respective approaches’ network
resource consumption. Based on the results we argue that
the content-based approach seems promising and should be
investigated further.
