Architecture
The JetSend architecture can be divided into three parts:
Device Code
Device Code—This code contains device-specific information such as the device
name, its address and its capabilities.
JetSend Core
JetSend Core—The core consists of an e-material library which is used to encode
information; the JetSend session protocol (JSP) which is used to open and close
communication sessions; and the JetSend interaction policy which governs the use
of these protocols.
There are four such policies: The Address Policy is used for communicating device
addresses. The Self Policy is used to exchange contact information (like exchanging
a business card). The Job Policy is used to send or receive jobs, and the Status
policy is used to exchange Job pass/fail data.
Link Layer
Link Layer—This part contains all the functionality needed for transporting the
information from the sending device to the receiving device.
