Hi Chao,
I don't believe that it is currently possible to customize the file
names in the ways you have described using the standard begin_ditaa
blocks. It is possible to have complete control over the file names
using org-babel, in which case the corresponding block would look like
--------
#+begin_src ditaa :file communication.png :exports results
blabla
#+end_src
--------
then the image will be created on export, and you can also preview the
image by pressing C-c C-o on the block.
To activate org-babel add the following to your Emacs configuration
(require 'org-babel-init)
(require 'org-babel-ditaa)
