“…In metropolitan level we have a situation which is more complex to choose a costeffective and high-performance technology, because different types of traffic and transmission rates are being transported, and high flexibility, adaptability and availability of transport capacity are required. Therefore, we also expect WDM to be both technically and economically the most attractive solution at the metropolitan level of optical networks [7][8][9].…”

This article evaluates the performance of Wavelength Division Multiplex (WDM) networks considering two different modes of photonic Switching: Optical Packet Switching (OPS) and Optical Circuit Switching (OCS). A resource distribution planning is proposed including wavelength/amplifier allocation to improve the blocking probability and to ensure signal quality. The present study considered the effects of signal attenuation and dispersion in mesh topology networks, and the actual utilization of each network link for the distribution of wavelengths and amplifiers. The physical network parameters considered had average diameter and average distance, as well as ASE noise accumulation and channel cross-talk. In order to evaluate and compare the performance between WDM-OCS and WDM-OPS, the following parameters were analyzed: delay (latency), blocking probability, and effective network-capacity utilization. Results show a reduction of blocking probability with a small increase in latency in both OCS and OPS, but the WDM-OPS combination presents results with very positive impact. Work was carried out with both analytic modeling and computer simulations.

“…However, the ever-increasing traffic in these networks requires increasing flexibility and availability of transport capacity, which is not totally compatible with the centralized control of these passive networks [3]. On the other hand, we believe that asynchronous OPS/OBS mesh topology solutions [1,2] can overcome these limitations and are better suited for packet-oriented applications [8,9]. Furthermore, avoiding opto-electric conversions along optical path route nodes saves time and energy.…”

“…In this work we focus on hybrid OPS/OBS network architectures based on mesh topologies. The simplicity of construction of the optical nodes when Photonic Switching is adopted is our base of choice on already demonstrated experiments [7,9]. The term hybrid comes from combination of nodes with different degrees/grades of interconnection (number of input-output ports) in the same network.…”

“…The present work is based on single wavelengths; and various single-wavelength networks can be interconnected with WDM systems [5,10]. It should be noted that the presently proposed networks, as well as other proposals [2] and demonstrations [7,9,10] are better suited for application in limited areas, mainly metropolitan traffic, not considering physical impairments. In case of geographical expansions, larger networks (more than 25 nodes) should be broken down to twice 16 or three times 9, according to specific situations [2].…”

Use of Photonic Switching in Optical Networks seems to be one of the best solutions for traffic optimization in Metropolitan Access. Here we propose optical packet/burst switching (OPS/OBS) networks as a future-proof solution for high-throughput in the highly variable traffic pattern of the metro-access. Through analytic modeling and computer simulations we evaluate network performance of mesh networks having a hybrid topology of the Manhattan St.-type. We combine nodes of interconnection grade-2 and grade-3 in order to optimize and balance simultaneously network performance and cost. For performance metrics the parameters packet loss fraction and average number of hops are adopted, link and node loads are investigated, and effective network capacity is evaluated. Results clearly indicate improvement of capacity over grade-2 networks, and possibility of cost savings over complete grade-3 installations.
