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...
Traffic matrices play a pivotal role in the management of an ISP's network such as various levels of traffic engineering and capacity planning. However, it is unclear how the...
Orthogonal Frequency Division Multiplexing (OFDM) has been recently proposed as a modulation technique for optical networks, due to its good spectral efficiency and impairment tole...

There exist a wide variety of network design problems that require a traffic matrix as input in order to carry out performance evaluation. The research community has not had at it...
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...
Abstract. In this paper we present OpenTM, a traffic matrix estimation system for OpenFlow networks. OpenTM uses built-in features provided in OpenFlow switches to directly and acc...
