From the Intro: In this document we discuss a framework to support terminal mobility that provides seamless handovers with low latency and low loss. Are there other components to terminal mobility aside from MPA? Section 1.2: A trade-off between one-way-delay and packet loss is desired based on the type of application. Unclear to me - a trade-off should be available through tuning or one-way-delay should be improved relative to packet loss? Section 3: Define "inter-subnet handover"? Section 6.1: MPA provides three basic procedures to provide this functionality. The first procedure is referred to as "pre-authentication", the second procedure is referred to as "pre-configuration", the combination of the third and fourth procedures are referred to as "secure proactive handover". "three basic procedures" and "third and fourth procedures" is confusing; where did that fourth procedure come from? Section 6.1: Especially, the third procedure described above (i.e., binding update procedure) Change "third procedure described above" to "step (iii) in the previous paragraph" to avoid confusion with the use of "procedures in the earlier paragraph in section 6.1. Section 6.2: The authentication protocol MUST be able to derive a key between the mobile node and the authentication agent and SHOULD be able to provide mutual authentication. Is "derive a key between ..." a term of art or can the requirement be described more accurately as "establish a shared key between..."? The authentication protocol SHOULD be able to interact with a AAA protocol such as RADIUS and Diameter to carry authentication credentials to an appropriate authentication server in the AAA infrastructure. Does the authentication protocol interact directly with the AAA protocol, or does the interaction happen through the AA?
