My concern is that there is no clear relation between 3.1.2 and 3.1.3.
In fact, many of the properties of 3.1.3 are the result of the interface
mentioned in 3.1.2. Also, a few aspects of the 3.1.2 interface aren't
considered in 3.1.3.
So what's the point of 3.1.3?
>From the definition:
Transport Protocol Component: an implementation of a transport
service feature within a protocol.
Unfortunately, the items in 3.1.3 aren't implementations; they're
general properties. An implementation would be Reno or CUBIC.
In addition, API isn't defined (e.g., see my previous 3 descriptions),
so it's never clear what should be in 3.1.2 (or the corresponding
sections of other protocols).
As a result, I do not understand the purpose of either section of this
document, or this document as a whole.
Joe
