As you Asking for the the information About the Infrared Data Association
(IrDA) Object Exchange Protocol is given below

OBEX is a compact, efficient, binary protocol that enables a wide range of devices to exchange data in a simple and spontaneous manner. OBEX is being defined by members of the Infrared Data Association to interconnect the full range of devices that support IrDA protocols.It is not, however, limited to use in an IrDA environment.

Performances

OBEX performs a function similar to HTTP, a major protocol underlying the World Wide Web. However, OBEX works for the many very usefuldevices that cannot afford the substantial resources required for an

HTTP server, and it also targets devices with different usage models from the Web. OBEX is enough like
HTTP to serve as a compact final hop to a device “not quite” on the Web.


OBEX is designed to fulfill the following major goals:
1. Application friendly - provide the key tools for rapid development of applications.
2. Compact - minimum strain on resources of small devices.
3. Cross platform.
4. Flexible data handling, including data typing and support for standardized types - this will allow
devices to be simpler to use via more intelligent handling of data inside.
5. Maps easily into Internet data transfer protocols.
6. Extensible - provide growth path to futureneeds like security, compression, and other extended
features without burdening moreconstrained implementations.
7. Testable and Debuggable.


OBEX Session Protocol

In object model that carries information aboutthe objects being sent, as well as containing the objects themselves. The object model is built entirely with parsable headers, similar in concept to the headers in HTTP.
A session protocol, which structures the dialogue between two devices. The session protocol uses a
binary packet-based client/server request-response model.
An IAS definition and hint bits for the service.
