The recent availability of new optical network elements makes possible to introduce new architectures and new functionality into the optical transport networks. Optical crossconnects and ultra long haul transmission equipment have emerged and opened a new opportunity to handle fully transparent connections and extend optically transparent domains. A translucent network is basically a network in...

Code Division Multiple Access (or CDMA) is a multiple access technique based on spectral spreading that has been tremendously successful in the wireless domain. The effectiveness of CDMA in applications like cellular networks, satellite systems and Wireless Local Loop systems has strongly contributed to maintaining the application of CDMA to the optical domain, also known as Optical CDMA, an ac...

This paper reviews the progress of the passive optical network, and discusses a viable means for the realisation of future generation agile gigabits passive optical networks, (GPONs) by the use of low cost narrow band tunable lasers and arrayed waveguide gratings (AWGs). It projectes a twostage strategy for the realisation of future generation agile GPONs, i.e., the near-term Time and Wavelengt...

A general overview of the current status and future trends in optical networking is given. Special attention is given to the coexistence of optical and electronic technologies in telecommunications networks. After reviewing the advantages of both technologies, their use in different network areas is discussed. A critical survey of current and new transport technologies in optical core and metro...

This invited paper describes about mobile wavelength division multiplexing (WDM) backhaul network designs for future radio access networks. First, it introduces mobile backhaul requirements to support LTE-Advanced and Beyond with emphasis on coordinated multipoints (CoMP) techniques. It primarily considers WDM passive optical networks (WDM-PON) as promising optical access technologies for mobil...

In this paper, the impact of burstification delay on the TCP traffic statistics is presented as well as a new assembly scheme that uses flow window size as the threshold criterion. It is shown that short assembly times are ideally suitable for sources with small congestion windows, allowing for a speed up in their transmission. In addition, large assembly times do not yield any throughput gain,...

We survey the theoretical results obtained for wavelength routing in all–optical networks, present some new results and propose several open problems. In all–optical networks the vast bandwidth available is utilized through wavelength division multiplexing: a single physical optical link can carry several logical signals, provided that they are transmitted on different wavelengths. The informat...

Two important issues related to the use of remotely-pumped erbium-doped fiber amplifiers in optical distribution networks are analyzed. We investigate the optimal allocation of gain and loss among the stages of a lumped amplifier chain, using the concepts of a Nash solution and Pareto optimality. The propagation of optical channels along an erbium-doped fiber is derived from basic physical cons...

We investigate benefits of setup-delay tolerance in elastic optical networks and propose an optimization model for dynamic and concurrent connection provisioning. Simulation shows that the proposed strategy offers significant improvement of the network blocking performance. © 2014 Optical Society of America OCIS codes: (060.0060 ) Fiber optics and optical communications; (060.4256) Networks, ne...

Deflection routing and burst segmentation are two techniques for resolving contention in optical burst-switched networks. By selectively applying these techniques to bursts with different QoS requirements, we can offer a range of differentiated services at the optical layer. c 2001 Optical Society of America OCIS codes: (060.4250) Networks
