Technical Summary
This document presents a congestion control algorithm which couples
TCP standard congestion control algorithms running on different subflows.
This coupled congestion control algorithm allows a flow that uses
multiple paths to utilize bandwidth efficiently while keeping the
fairness to other flows at the bottleneck.
Protocols such as Multipath TCP and SCTP which support multiple
end-points for a single flow benefit from this algorithm.
