A field selection graphical user interface (GUI) for use with a protocol analyzer. The GUI allows selecting a source presented by the GUI, selecting a field from a plurality of fields presented by the GUI associated with the selected source, defining one or more preconditions associated with the selected field from a plurality of preconditions presented by the GUI relevant to the selected field, and calculating a field layout in accordance with the selected field and defined one or more preconditions. The GUI further allows selecting a second field from the plurality of fields presented by the GUI associated with the selected source, defining one or more preconditions associated with the selected second field from a plurality of preconditions presented by the GUI relevant to the selected second field, and calculating a field layout in accordance with the selected field and the second field.

Field selection graphical user interface

Apparatus and associated systems and methods may relate to a data traffic modification system that may receive operating code developed using a graphical user interface (GUI) that permits substantially real-time editing of instructions that have been determined to include errors. In various implementations, a data traffic modification device may selectively modify data traffic upon the occurrence of a predetermined condition. In one illustrative example, operating code may be developed by sequentially editing individual instructions. Upon modifying each instruction, the validity of the operating code with the edited instruction may be checked, and the GUI may display the updated code substantially in real time during an editing session. The GUI may display an indication of the validity status of the set of instructions. In some embodiments, the user may be permitted to continue editing the code within the GUI while the set of instructions contains errors.

Code editing for data traffic modification

Apparatus and associated systems and methods may relate to a data traffic modification system that may include a processing module to handle SATA-compliant data transfers in which a source device or a target device issues requests to pause and subsequently to resume the data transfer. In various implementations, a data traffic modification device may selectively modify data traffic upon the occurrence of a predetermined condition. In one illustrative example, if a target device for the data transfer issues a pause request (e.g., to prevent a buffer overflow), the data traffic modification device may generate a pause acknowledge signal to the target device within a response time specified by the protocol. In another illustrative example, if a source device for the data transfer issues a pause request, the data traffic modification device may generate a pause acknowledge signal to the source device within the response time specified by the protocol.
