Trajanovski, S. (author), Kuipers, F. A. (author), Van Mieghem, P. (author), Ili?, A. (author), Crowcroft, J. (author)Due to the importance of communication networks to society, it is pertinent that these networks can withstand failures. Improving the robustness of a network usually requires installing redundant resources, which is very costly. Network providers are consequently less inclined to take robustness measures against failures that are unlikely to...conference paper 2013

Trajanovski, S. (author), Kuipers, F. A. (author), Van Mieghem, P. (author)It is important that our vital networks (e.g., infrastructures) are robust to more than single-link failures. Failures might for instance affect a part of the network that resides in a certain geographical region. In this paper, considering networks embedded in a two-dimensional plane, we study the problem of finding a critical region - that is,...conference paper 2013

Pol, R van der (author), Bredel, M (author), Barczyk, A (author), Overeinder, B (author), van Adrichem, N.L.M. (author), Kuipers, F.A. (author)The size and amount of e-science data sets is growing rapidly. Keeping up with the network demand in order to transfer these data sets over the Internet is a challenge. Single links do not have enough capacity anymore. Therefore we need to install more interfaces in the servers and use all available paths in the network. In this paper we...conference paper 2013

Kuipers, F.A. (author)Network survivability—the ability to maintain operation when one or a few network components fail—is indispensable for present-day networks. In this paper, we characterize three main components in establishing network survivability for an existing network, namely, (1) determining network connectivity, (2) augmenting the network, and (3) finding...conference paper 2012

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

Van de Bovenkamp, R. (author), Kuipers, F. (author), Van Mieghem, P. (author)We propose Gossipico, a gossip algorithm to average, sum or find minima and maxima over node values in a large, distributed, and dynamic network. Unlike previous work, Gossipico provides a continuous estimate of, for example, the number of nodes, even when the network becomes disconnected. Gossipico converges quickly due to the introduction of a...conference paper 2012

Beshir, A. (author), Nuijts, R. (author), Malhotra, R. (author), Kuipers, F. (author)Traffic grooming allows efficient utilization of network capacity by aggregating several independent traffic streams into a wavelength. In addition, survivability and impairment-awareness (i.e., taking into account the effect of physical impairments) are two important issues that have gained a lot of research interest in the area of optical...conference paper 2011

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

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
