I found this evaluation to be very sketchy. I will try to ask some specific questions: It is not at all clear to me whether the midcom agents is intended to be a diameter client, or server. My understanding (and please feel free to correct me if I am wrong in this regard) is that Diameter, like Radius, is a client / server where the client sends requests to the server and receives responses. Even if there are some additional reverse direction messages for special cases, this seems to be the predominant mode. The midcom protocol predominant mode is an invocation be a midcom agent requesting a behavior of a middlebox. This would lead one to the odd situation of expecting the midcom agent to be a diameter client, and a middlebox to be a diameter server. There is a reference to AVP grouping to address the aggregation requirement. As I am not particularly familiar with the Diameter details, it would be helpful if you mentioned whether this grouping is ad hoc (in which case it address the requirement thoroughly) or is defined via a schema / RFC / ... On a number of the requirements, somewhat more elaboration of the Diameter behavior would be helpful. Even once I know which side is the client and which the server, I suspect that issues of state maintenance, overlapping control, and related items which you feel are addressed easily could be described a little better.
