The IoT requires a fabric-based service broker
The IoT needs a service broker which collapses web services, SOA, ESB, Security, Privacy and translation/transformation allowing any protocol, any platform from any provider to communicate.

This archaic thinking may have been true in legacy M2M however with the introduction of the Internet and numerous applications and humans acting as potential control/analytics as well as need to integrate supplier infrastructures into the ecosystem you need intelligent purposeful engagement capabilities that do not dictate a silo approach and complete change of systems According to Stan Schneider from RTI, if I recall correctly, there will be no LAN and WAN in architecture. I completely understand this focus as DDS only allows this, however it is not the case, there will always be separation between LAN and WAN or a “Hierarchy”.
