Hi Tom One of the other tools which is currently being tested called iRods has this capability/option you are referring to built into it. Does OODT have something similar or how would it be done?
Here is the definition of the checksum we want to perform given on the confluence page: "A checksum or hash sum is a small-size datum from an arbitrary block of digital data for the purpose of detecting errors which may have been introduced during its transmission or storage." Does this help?

My first thoughts were that a checksum using TCP is not necessary since the protocol takes care of the data integrity but there seems to be a requirement for this in the test plan to have a chescksum capability. Not to confuse issues, but I perform an md5sum on all data files (hdf5 files) once they have been created and store it as metadata for the file. Does the requirement maybe not refer to this? I would like to test a UDP protocol with a checksum calculation as well for some comparison. Please let me know if you has success with implementing/using this functionality! I will also have a look at the UDT transport mechanism as you proposed. Woot!
