The Internet of Things / Message Queue Telemetry Transport / NCW / NDN Comparison

The Internet of Things, Named Data Networking, Net Centric Warfare in context with protocols such as MQTT and DDS -- Message Queue Telemetry Transport share a publish-subscribe messaging protocol, interest based on content represented by class type conventions such as eXtensible Markup Language XML content <//tags> and a cyclic, reliable update of state. Named Data Networking Interest is based on state meta data class type subscription changes.

Publish–subscribe is a messaging pattern where senders of messages, called publishers, do not program the messages to be sent directly to specific receivers, called subscribers. Instead, published messages are characterized into classes, without knowledge of what, if any, subscribers there may be. Similarly, subscribers express interest in one or more classes, and only receive messages that are of interest, without knowledge of what, if any, publishers there are. Pub/sub is a sibling of the message queue paradigm, and is typically one part of a larger message-oriented middleware system. Most messaging systems support both the pub/sub and message queue models in their API, e.g. Java Message Service (JMS). This pattern provides greater network scalability and a more dynamic network topology, with a resulting decreased flexibility to modify the Publisher and its structure of the data published.
