I know this is about 5 years old at this point, but, we are also trying to make smart routing decisions based on DICOM info. There are iRule possibilities, but iRule documentation is extremely segmented with few examples outside of "web" traffic, like the previous answer. Those of us looking for deeper solutions, looking into the TCP packet to make decisions, not much out there. However, to this person I would have said, for modality type based decisions, invest in a DICOM Router like Laurel Bridge Compass. It has the ability to make routing decisions based on DICOM information it gathers from the DICOM headers (HTTP examples, etc are useless in DICOM). Laurel Bridge also has a basic 'balancing' (round robin with heartbeat sensing), so it can get close to th Big IP in that aspect. I wish there more support for non HTTP in the Big IP world, better documentation, etc. Until then, right now it's either become an iRule guru and figure it out on your own or look for another solution.
