Connectivity Framework 1 : Introduction
1 INTRODUCTION
Ubiquitous connectivity is one of the foundational technologies enabling data sharing amongst participating components of an Industrial Internet of Things ( IIoT ) system .
Connectivity provides the ability to exchange data amongst participants within a functional domain , across functional domains within a system and across systems . The data exchanged may include sensor updates , events , alarms , status changes , commands , and configuration updates . Connectivity is a crosscutting function across the functional domains defined by the Industrial Internet Reference Architecture 1 , as shown in Figure 1-1 .
