“…The recent introduction of transparency, as well as the necessity to re-use legacy fiber as much as possible, brings new challenges in the efficient design of meshed optical networks, for instance coping with line fiber type heterogeneity. Indeed, it has now become almost common to deal with light-paths between two points of the network involving at least two different line fiber types [7,8,[36][37][38][39][40], and it has therefore become crucial to use simple tools in order to predict accurately light-path feasibility. One of the most critical issues is to determine the tolerance to Kerr-like non-linear impairments, without requiring customized simulations or experiments for each possible configuration.…”

This article introduces the issues of design and estimation of performance of a heterogeneous optical transmission system, taking into account the multiplicity of physical effects impairing propagation simultaneously, and, most particularly, the impact of Kerrinduced non-linear effects. We review the usual engineering tools enabling us to predict system performance, as well as design tools to optimize dispersion-management. Finally, we introduce the concept of weighted non-linear phase shifts, to capture the impact of the accumulated non-linearities on a propagating signal, and derive analytical expressions for system reach and power optimization in the context of highly heterogeneous optical link with mixed fiber features.

“…W avelength division multiplexing (WDM) technology has enabled efficient communications by combining hundreds of high-speed wavelength channels onto a single fiber for parallel data transmission [1]. Nowadays, the bandwidth of a wavelength channel can be 40 Gbps [2] or above, whereas most subrate applications only require a bandwidth much less than this level. If the conventional circuit switching is carried out by taking the full bandwidth of a wavelength as the smallest granularity, each subrate application will engross a full wavelength capacity, which will seriously underutilize the bandwidth.…”

We design virtual topologies in wavelength division multiplexing (WDM) networks to minimize the network diameter and average hop count, where network diameter refers to the number of hops of the longest shortest path and average hop count is the average number of hops among the shortest paths of all node pairs. Such objectives are important to WDM networks, especially to those with statistical multiplexing mechanisms such as optical burst switching (OBS) and optical packet switching (OPS). By minimizing the network diameter and average hop count, optical packets or bursts will experience less contention loss and smaller delay due to a reduced number of intermediate nodes en route. In this paper, we first formulate an integer linear program (ILP) for optimal design of virtual topologies with minimized network diameter and average hop count. Then, a novel heuristic least weight minimum diameter (LWMD) is proposed to find good solutions efficiently. Based on the virtual topology obtained, we further design two traffic accommodation schemes to provision wavelengths under a given traffic matrix, with guaranteed network diameter and minimized network resource consumption.

“…It is possible that a pure m-cycle solution is not sufficient to achieve unambiguous link failure localization (i.e., identify each link failure using a unique alarm code). For example, the failures at links (2,4) and (3,4) in Fig. 1b have the same alarm code as shown in Fig.…”

“…In Fig. 1b, an extra link-based monitor can be used at either (2,4) or (3,4). This increases the total number of monitors from 3 to 4, but it is still less than 7, as required by a pure link-based monitoring scheme.…”
