0 A New Analysis for Wavelength Translation in Regular WDM Networks /vsharma87/massiveleyparallel97 massiveleyparallel97-140612020103-phpapp02
We present a new analysis of wavelength translation in regular, all-optical WDM networks, that is simple, computationally inexpensive, and accurate for both low and high network loads. In a network with k wavelengths per link, we model the output link by an auxiliary M/M/k/k queueing system. We then obtain a closed-form expression for the probability P succ that a session arriving at a node at a random time successfully establishes a connection from its source node to its destination node. Unlike previous analyses, which use the link independence blocking assumption, we account for the dependence between the acquisition of wavelengths on successive links of the session’s path. Based on the success probability, we show that the throughput per wavelength increases superlinearly (as expected) as we increase the number of wavelengths per link; however, the extent of this superlinear increase in throughput saturates rather quickly. This suggests some interesting possibilities for network provisioning in an all-optical network. We verify the accuracy of our analysis via simulations for the torus and hypercube networks. ]]>

Designing & managing operational IP networks is a complex, multi-dimensional task. A fundamental problem before carriers today is to optimize network performance by better resource allocation to traffic demands. This requires a systematic evaluation of options, a thorough scenario analysis, and foolproof verification of network designs, all of which are increasingly possible only with help from automated TE and planning tools. In the past few years, significant advances have been made in enhancing existing tools and developing new ones that help providers rapidly identify potential performance problems, experiment with solutions, and develop robust designs. Several techniques from optimization theory, linear programming, and models of effective bandwidth calculation have been incorporated in such tools, as have detailed models of several vendor systems. We present a comparative analysis and an overview of key features of some key commercially available network planning/TE tools, and outline how they could be leveraged by carrier network engineering/planning organizations to perform detailed network analysis, proactive/reactive TE, and network design. We first give an overview of the architecture, design philosophy, and canonical features of modern design tools, and then focus on new enhancements to some popular tools as well as key distinguishing features of some newly developed ones. In particular, we focus on decision support tools for IP network planning and network analysis, including the latest versions from WANDL, OPNET, Cariden.. We also present a perspective on current outstanding carrier requirements for TE/planning tools that was synthesized by our conversations with several leading Tier 1 and Tier 2 carriers.]]>
