Gradually reconfiguring virtual network topologies based on estimated traffic matrices
Traffic matrix, which is required as an input of traffic engineering (TE) methods, is difficult to be obtained directly. One possible approach to obtaining the traffic matrix is to...

Domination Between Traffic Matrices
A traffic matrix D1 dominates a traffic matrix D2 if D2 can be routed on every (capacitated) network where D1 can be routed. We prove that D1 dominates D2 if and only if D1 , cons...
