# fnss.adapters.ns2.to_ns2

`to_ns2`(topology, path, stacks=True)

  Convert topology object into an ns-2 Tcl script that deploys that topology into ns-2.

  Parameters: | topology : Topology The topology object to convert path : str The path to the output Tcl file stacks : bool, optional If True, read the stacks on nodes and write them into the output file. For this to work, stacks must be formatted in a way understandable by ns-2. For example, stack and applications must have a ‘class’ attribute whose value is the name of the ns-2 class implementing it.

  Notes

  In order for the function to parse stacks correctly, the input topology must satisfy the following requirements:

  > - each stack and each application must have a class attribute whose value is the ns-2 class implementing such stack or application, such as Agent/TCP or Application/FTP.
  > - All names and values of stack and application properties must be valid properties recognized by the ns-2 application or protocol stack.
