    The transmission control protocol (TCP) is the major trans- port protocol in the Internet. TCP and its variants have the drawback of not accurately knowing rate share of flows at bottleneck links. Some protocols proposed ...

    A linear differential operator often has a nontrivial null space. One consequence for such an operator, L, is that solutions of equations of the form Lu=f are never unique if the null space contains more than the zero ...
