The unprecedented growth of the global Internet traffic, coupled with the large spatio-
temporal fluctuations that create, to some extent, predictable tidal traffic conditions, are …

The wave function of a composite system is defined in relativity on a space–time surface. In
the explicitly covariant light-front dynamics, reviewed in the present article, the wave …

Bulk transfer on the wide-area network (WAN) is a fundamental service to many globally-
distributed applications. It is challenging to efficiently utilize expensive WAN bandwidth to …

We present a new approach to the virtual-topology reconfiguration problem for a wavelength-
division-multiplexing-based optical wide-area mesh network under dynamic traffic demand …

Fiber cut events reduce the capacity of wide-area networks (WANs) by several Tbps. In this
paper, we revive the lost capacity by reconfiguring the wavelengths from cut fibers into …

One approach to accommodating traffic on a wavelength-routed optical network is to
construct a virtual network topology (VNT) by establishing a set of lightpaths between nodes …

ISP networks have become a critical infrastructure in our society. Traffic in these networks is
growing and is increasingly dominated by a small number of large CDNs connecting at …

Optical networks and the related technologies, network management software and services
have undergone remarkable developments, and such networks are now the ultra-high …

Coupling MPLS traffic engineering on top of a wavelength-routed WDM layer offers great
flexibility to operators to allocate traffic demands in their networks. We consider the problem …

Optical networks employing wavelength division multiplexing can carry huge volumes of
traffic, hence maintaining a high level of service availability is important. This makes fault …
