Joint Architecture Standard Overview Profile
The JAS architecture defines a small number of Profiles that form the basis for building the components required for a sensor interface and data processing electronics system. A node inherits the attributes of one or more Profiles. A Profile describes the purpose of that node within the Architecture and defines how that node interacts with other nodes. Specific functions within a system are defined as instantiations of one of the JAS Profiles. The number and type of nodes required depends on the mission requirements. The system can be scaled to meet a wide range of processing requirements.
Conceptually, this architecture is very similar to an Object-Oriented (OO) programming methodology where objects inherit the properties of a class and extend that functionality to meet specific user needs. A Profile can be viewed as a class of hardware functionality providing a baseline set of electrical, mechanical, interface, and communications attributes. Specific mission functions are objects built upon the defined set of classes, or Profiles.
