iRule to route DICOM by study type

Sine F5 doesn't have a way to read the metadata or EXIF data in DICOM images, you would need another way to identify the study type. If you can have a file name policy or add a path for transfer to the PACS, the F5 could interpret that as the study and change the pool on the fly pretty easily.

You can also take some tcp dumps from the live F5 without effect to the production system by using tcpdump or tshark.

If you have APM, you could also base pool selection on the authenticated user. So for example, A user would authenticate, APM would determine they are in the Tomography department, and F5 would set CT_pool.

Something like the following, without APM MAY work if you have a standard naming policy:

when HTTP_REQUEST {
  if { [HTTP::path] contains "mammo" }{
    pool mammo_pool
  } elseif { [HTTP::path] contains "tomo" }{
    pool tomo_pool
  } else {
    pool pacs_pool
  }
