Block Name: Layer_Complete

Code File Location: VisualSim/Actor/lib/Layer_Complete

Block Overview

• The Layer_Complete block completes the Protocol Layer process by calling back the appropriate Layer_Protocol block signalling the completion of either an up or down protocol layer process. The 'Layer_Configuration' parameter in the 'Layer_Table' Block must be set to 'External_Delay' for this block to be used.  This block can be used at the end of a layer-specific processing such as TCP details to return the control to the Layer_Protocol block and send the data up or down the stack.

Description

This block allows the user to return the original data structure back to the Layer_Protocol for transmitting up or down the protocol stack.  The right-side port allows the user to describe an alternate logic/timing for the transfer up the stack.  Similarly, the left-side port allows the user to describe an alternate logic/timing for the transfer down the stack.  

A Layer Complete block returns an external up or down packet to the Protocol_Layer that it originated from, via a virtual connection.  The Layer_Table block parameter Layer_Configuration must be set to "External_Delay" for a packet to exit the Layer_Protocol block for external processing.
