Hi David,

that is an interesting document. Here are some initial comments:

* I don't think you need in Section 2 the RFC 2119 boiler plate.
* In some place you refer to RTP. How is the proposed solution
  specific to RTP? Couldn't you use this also to detect shared
  bottlenecks for MP-TCP subflows or SCTP-CMT?
* Is it possible to do the computations without floating point
  operations? This might be important when trying to implement
  this in operating systems kernels.

Best regards
Michael
