DESCRIPTION:The recent developments of multipath data transport protocols 
 allow end-systems to explore and share available resources within networks
 . Through dynamic load balancing over subflows these protocols ensure high
  levels of robustness to network failures and traffic overloads. In this t
 alk we use fluid models to study the benefits that accrue when load is sha
 red across subflows. We combine insights gained from the fluid models with
  a precise description of the capacity region for the network and show tha
 t our models of multipath protocols approach the boundary of the capacity 
 region as the intensity of the offered traffic approaches a critical value
 . Additionally\, we quantify the extent to which multipath protocols will 
 make a network robust to unforeseen traffic mismatches and link failures.
