## Abstract

A portable distributed application framework that uses a definition file describing a structure of data and commands to be used by the framework to interface with an application. A proxy, responsive to a definition file, creates and receives messages based on the definition file. The created messages contain data and commands used to control the application while the received messages contain data from the application. A control, responsive to the definition file, relays messages between the proxy and the application. A housing, responsive to the definition file and the messages from the proxy, provides the application with configuration information and receives data from the application.

## Claims

### Claim 1

A protocol emulation system comprising:
at least one emulation housing configured by a protocol emulation definition for initiating protocol emulation sessions in accordance with data contained in the protocol emulation definition file; and
an interface including a display, configured by the protocol emulation definition, that displays data related to the session created by the emulation housing and facilitates the entry of commands and configuration data from a user, the commands and configuration data being transmitted to the emulation housing and modifying the behavior thereof; and
an emulation controller that distributes protocol emulation definitions and acts as a conduit of data and commands between the emulation housing and the interface.

### Claim 2 (depends on 1)

A protocol emulation system, as set forth in claim 1, wherein the emulation housing uses the protocol emulation definition file to construct a data structure storing data used during operation.

### Claim 3 (depends on 1)

A protocol emulation system, as set forth in claim 1, wherein the interface uses the protocol emulation definition file to construct a reference model storing data used during operation.

### Claim 4 (depends on 3)

A protocol emulation system, as set forth in claim 3, wherein the emulation housing uses the protocol emulation definition file to construct a reference model storing data used during operation.

### Claim 5 (depends on 4)

A protocol emulation system, as set forth in claim 4, wherein the interface uses the reference model to instantiate messages for the emulation housing.

### Claim 6 (depends on 4)

A protocol emulation system, as set forth in claim 4, wherein the emulation housing uses the reference model to instantiate messages for the interface.

### Claim 7 (depends on 1)

A protocol emulation system, as set forth in claim 1, further comprising:
a protocol state machine in communication with the emulation housing, the protocol state machine creating and responding to protocol messages.

### Claim 8 (depends on 1)

A protocol emulation system, as set forth in claim 1, further comprising:
scripts describing how to create and respond to protocol messages; and
wherein the emulation housing passes received protocol message to the scripts and transmits responses generated by the scripts onto a network under test.

### Claim 9 (depends on 1)

A protocol emulation system, as set forth in claim 1, wherein the interface comprises a graphical user interface that creates a display based on information contained in the protocol emulation definition.

### Claim 10 (depends on 1)

A protocol emulation system, as set forth in claim 1, wherein the interface is textual.

### Claim 11 (depends on 1)

A protocol emulation system, as set forth in claim 1, wherein the interface is created using a script language.
