As WDM technology matures, IP over WDM multicast becomes a new challenging topic. Supporting multicast at the WDM layer provides additional advantages, but also raises many new issues that do not exist in IP multicast. For example, the limitation on the light splitting capability of switches is one major difficulty in WDM multicast, and in addition, the limitations on both the wavelength conver...

We describe a source-rooted WDM multicast tree construction protocol to support IP dense mode multicast routing protocols in all-optical lambda-switched networks. Using a receiver-initiated approach, the protocol relies on a mechanism that collects information on the capabilities of WDM nodes. This mechanism provides receivers with sufficient information to setup WDM multicast trees in networks...

The Wiener diffusion model (WDM) for 2-alternative tasks assumes that sensory information is integrated over time. Recent neurophysiological studies have found neural correlates of this integration process in certain neuronal populations. This paper analyses the properties of the WDM with two different boundary conditions in decision making tasks in which the time of response is indicated by a ...

The fiber-optic communication lines and transmission systems using cable, receiving transmitting optical modules based on WDM DWDM (Wavelength Division Multiplexing & Dense WDM) technologies are studied. A method for calculating the characteristics is proposed relationships obtained that establish an analytical relationship between length regeneration section rate. This paper discusses stud...

The impetus focus is on to provide high data transfer and utilization of high bandwidth, so the era of computer networks completed a journey from co-axial, twisted pairs cables to optical cables migrating from SONET/SDH to WDM technology based networks. This paper deals with various aspects concerned to WDM based networks in context to failure of fiber links in WDM optical networks and the surv...

Problem statement: Hybrid Optical Code-Division Multiple-Access (OCDMA) and Wavelength-Division Multiplexing (WDM) have flourished as successful schemes for expanding the transmission capacity as well as enhancing the security for OCDMA. However, a comprehensive review related to this hybrid system are lacking currently. Approach: The purpose of this paper is to review the literature on OCDMA-W...

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...

Current means of providing loop-back recovery, which is widely used in SONET, relies on fiber-based recovery, where a fiber is used to back up another fiber. We present WDM-based loop-back recovery for optical networks where wavelengths are used to back up other wavelengths. We present two new algorithms for performing WDM-based loop-back over optical mesh networks. The first algorithm performs...

As the Internet and network technologies evolve, the IP over WDM solution has been envisioned as the most promising solution for the next generation Internet architecture. So survivability in IP/WDM networks becomes critical for the success of the next generation Internet architecture. Considerable research efforts have been dedicated to studying the survivability in IP/GMPLS and WDM network re...
