Beshir, A. (author), Yannuzzi, M. (author), Kuipers, F. (author)With the increasing deployment of wavelength division multiplexing (WDM) optical networks, the need for advanced lightpath provisioning algorithms and protocols in a multi-domain setting is becoming evident. In order to increase efficiency by relaxing the wavelength continuity constraint in WDM optical networks, wavelength converters are often...conference paper 2010

Kuipers, F.A. (author), Beshir, A.A. (author), Orda, A. (author), Van Mieghem, P. (author)Physical impairments, such as noise and signal distortions, negatively affect the quality of information transfer in optical networks. The effect of physical impairments predominantly augments with distance and bit rate of the signal to the point that it becomes detrimental to the information transfer. To reverse the effect of physical...conference paper 2010

Beshir, A.A. (author), Kuipers, F.A. (author)A survivable connection usually requires computing link-disjoint primary and backup paths. Finding a min-sum pair of link-disjoint paths whose total cost is minimized can be solved in polynomial time. However, adding extra requirements may render the problem NP-complete. In this paper, we study different variants of the min-sum link-disjoint...conference paper 2009

Van Adrichem, N.L.M. (author), Van Asten, B.J. (author), Kuipers, F.A. (author)Although Software-Defined Networking and its implementation OpenFlow facilitate managing networks and enable dynamic network configuration, recovering from network failures in a timely manner remains non-trivial. The process of (a) detecting the failure, (b) communicating it to the controller and (c) recomputing the new shortest paths may result...conference paper 2014

Lu, Y. (author), Zhao, Y. (author), Kuipers, F.A. (author), Van Mieghem, P. (author)More and more free multi-party video conferencing applications are readily available over the Internet and both Server-to-Client (S/C) or Peer-to-Peer (P2P) technologies are used. Investigating their mechanisms, analyzing their system performance, and measuring their quality are important objectives for researchers, developers and end users. In...conference paper 2010

Ter Mors, A.W. (author), Witteveen, C. (author), Zutt, J. (author), Kuipers, F.A. (author)In context-aware route planning, there is a set of transportation agents each with a start and destination location on a shared infrastructure. Each agent wants to find a shortest-time route plan without colliding with any of the other agents, or ending up in a deadlock situation. We present a single-agent route planning algorithm that is both...conference paper 2010

Trajanovski, S. (author), Kuipers, F.A. (author), Hayel, Y. (author), Altman, E. (author), Van Mieghem, P. (author)Forming, in a decentralized fashion, an optimal network topology while balancing multiple, possibly conflicting objectives like cost, high performance, security and resiliency to viruses is a challenging endeavor. In this paper, we take a game-formation approach to network design where each player, for instance an autonomous system in the...conference paper 2015

Tang, S. (author), Lu, Y. (author), Martín Hernández, J. (author), Kuipers, F.A. (author), Van Mieghem, P. (author)In recent years, a number of commercial peer-to-peer TV (P2PTV) applications have been launched. Yet, their mechanisms and characteristics are unknown. In this paper, we study SopCast, a typical proprietary P2PTV system. Treating SopCast as a black box, we perform a set of experiments that are suitable to analyze SopCast in depth. We attempt to...conference paper 2009

Yang, S. (author), Kuipers, F. (author)Spectrum-sliced elastic optical path (SLICE) technology offers a more flexible bandwidth allocation in optical networks than wavelength division multiplexing. It allows different connections to be served via different modulation formats. However, as with any optical network, the optical signal may be susceptible to signal impairments, especially...conference paper 2012

Beshir, A.A. (author), Kuipers, F.A. (author), Van Mieghem, P. (author), Orda, A. (author)In WDM networks, survivable routing and wavelength assignment (SRWA) involves assigning link-disjoint primary and backup lightpaths. In the on-line SRWA problem, a sequence of requests arrive and each request is either accepted or rejected based only on the input sequence seen so far. For special networks, we establish on-line algorithms with...conference paper

Iqbal, F. (author), Smets, R. (author), Kuipers, F.A. (author)The points-of-presence of optical networks are interconnected by photonic paths capable of carrying Terabits of data. However, signals along those photonic paths accumulate transmission impairments and thus can be unreadable at the receiver if the accumulated impairments are too high. Our contributions in this paper are three-fold: (1) we...conference paper 2015

Kuipers, F. (author), Kooij, R. (author), De Vleeschauwer, D. (author), Brunnström, K. (author)Quality of Experience (QoE) relates to how users perceive the quality of an application. To capture such a subjective measure, either by subjective tests or via objective tools, is an art on its own. Given the importance of measuring users’ satisfaction to service providers, research on QoE took flight in recent years. In this paper we present...conference paper 2010
