“…respectively.) Then, the probability that all W wavelength channels are busy on the link is given by the MIMImlK Markov chain with k customer arrival classes is determined from [7] as: (3) where Gis G= (4) Let there be n WDM switches between two access stations. Then the probability that a burst from an access station destined to another access station is blocked, Bp, is given as: (assuming that each WDM NE blocks the burst independently. )…”

“…Multi-wavelength reconfigurable optical networks offer such a capability beyond current transport technologies such as SONET. The Multi-wavelength Optical Networking Program (MONET) [1] [2] [3] [4] sponsored by the U.S. Government's Defense Advanced Research Project Agency (DARPA) is a research consortium aimed at addressing the technology, architecture, and the management and control issues for this new emerging technology.…”

We describe the architecture, performance analysis and simulation result of a novel switching paradigm for optical WDM networks called Just-In-Time Optical Burst Switching (JIT-OBS) designed for ultra-low-latency transport of data-bursts across an optical WDM network. It combines the desirable features of circuit-switching and packet-switching, and features an out-of-band signaling scheme on a separate control channel with explicit feedback on delivery of data-bursts. We provide a performance analysis and simulation of the JIT-OBS approach, and compare its performance with those of circuit-switching and packet-switching approaches. We find that it has the best latency performance among the different switching mechanisms, and it has a better throughput performance than circuit-switching, and its performance is insensitive to network propagation delays.

“…Monitored parameters provided by the optical WDM layer are mostly low level analog signal parameters such as optical signal power, optical SNR, and wavelength registration measurements [29] bearing weak qualitative relations to the high level IP layer observable properties. Likewise, the IP layer's performance monitoring produces soft metrics which bear no simple deterministic correlation to the WDM layer measurements.…”

Given the ever increasing demand for network bandwidth, and the recent phenomenal advances in optical wavelength division multiplexing (WDM) networking technologies, a major component of the Next Generation Internet will be an Internat protocol (IP)-based optical WDM network. As IP over WDM networking technologies mature, a number of important architectural, management and control issues have surfaced. These issues need to be addressed before a true Next Generation Optical Internet can emerge. In this paper, we enumerate some of the key architectural, management and control issues and discuss corresponding approaches and advances made toward addressing these issues. We first review the different IP/WDM networking architectural models and their tradeoffs. We outline and discuss several management and control issues and corresponding approaches related to the configuration, fault, and performance management of IP over dynamic WDM networks. We present an analysis and supporting simulation results demonstrating the potential benefits of dynamic IP over WDM networks. We then discuss the issues related to IP/WDM traffic engineering in more detail, and present the approach taken in the NGI SuperNet Network Control and Management Project funded by DARPA. In particular, we motivate and present an innovative integrated traffic-engineering framework for reconfigurable IP/WDM networks. It builds on the strength of multiprotocol label switching for fine-grain IP load balancing, and on the strength of reconfigurable WDM networking for reducing the IP network's weighted-hop-distance, and for expanding the bottleneck bandwidth.
