In the last decade, energy efficiency in backbone networks has become an important problem due to the significant growth in the Internet traffic. A very promising solution to solve this problem in Internet Protocol (IP) over Wavelength Division Multiplexing (WDM) networks is the Virtual Topology Adaptation approach, which permits adapting network resources by following a dynamic daily traffic p...
Wavelength division multiplexing (WDM) switching has been emerging as the dominant technology in optical networks. In this paper, we study the switching performance of WDM optical packet switch (OPS) equipped with tunable wavelength converter sharing dedicated to each output fiber line under self-similar variable packet length traffic. In this study, we model WDM OPS employing tunable wavelengt...
We develop algorithms for the design of optical packet-switched networks. These algorithms are aimed at upgrading an existing ber-based, network infrastructure, such as the NSFNET backbone, by using Wavelength Division Multiplexing (WDM) technology. The network architecture employs wavelength-routing optical switches which enable the establishment of all-optical, WDM channels, called lightpaths...
An optical fiber can potentially have more than 30 THz of bandwidth that can be exploited by future generation broadband ISDN networks. However, because of the mismatch between optical transmission and electronic processing, the network transmission rate cannot exceed few Gbps. One popular solution to this problem is to employ wavelength division multiplexing (WDM) by fragmenting the whole band...
An IP (Internet Protocol) over WDM network is expected to be an infrastructure for the next–generation Internet by directly carrying IP packets on the WDM–based network. Among several architectures for IP over WDM networks, one promising way is to overlay a logical topology consisting of lightpaths over the physical WDM network so that IP packets are carried on the lightpaths. The conventional ...
The popularity of the Internet leads to an increasing number of emerging applications operating with the corresponding Internet protocol (IP). High bandwidth transmission over Internet links is one building block to provide audio & video applications apart from common data transport over the Internet protocol, thus enabling applications like computer-supported cooperative work (CSCW). While the...
Recent development in optical networking employing wavelength division multiplexing (WDM) fulfills the high bandwidth demand applications. Failure of such networks, leads to enormous data and revenue loss. Protection is one of the key techniques, which is used in designing survivable WDM networks. In this paper we compare dedicated and shared protection strategies employed in WDMmesh networks t...
