Efficient Multiple Multicast in WDM Networks

چکیده
This paper addresses the problem of multiple multicast in WDM networks. It presents three efficient algorithms to construct an optimal/sub-optimal multicast tree for each multicast and minimise the network congestion on wavelengths. The first two algorithm achieve an optimal network congestion for a specific class of networks whose all wavelengths are globally accessible and convertible at a unit cost. The third algorithm produces an approximation solution for the general case of WDM networks. key words: algorithm, communication, multicast, WDM networks

Multicasting in Multihop Optical WDM Networks with Limited Wavelength Conversion
This paper provides an overview on efficient algorithms for multicasting in optical networks supported by Wavelength Division Multiplexing (WDM) with limited wavelength conversion. We classify the multicast problems according to offline and on-line in both reliable and unreliable networks. In each problem class, we present efficient algorithms for multicast and multiple multicast and show their...

ÐWith ever increasing demands on bandwidth from emerging bandwidth-intensive applications, such as video conferencing, E-commerce, and video-on-demand services, there has been an acute need for very high bandwidth transport network facilities. Optical networks are a promising candidate for this type of applications. At the same time, many bandwidth-intensive applications require multicast servi...
متن کاملA Survey on Multicast Routing Approaches in Wireless Mesh Networks
Wireless mesh networks (WMNs) which mediates the broadband Internet access, have been recently received many attentions by the researchers. In order to increase capacity in these networks, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi-channel WMNs (MRMC WMNs). Therefore, a vital challenge that poses in MRMC WMNs is how to properly assign channels ...

We address the issue of providing efficient mechanisms for multidestination communication over one class of lightwave wavelength division multiplexing (WDM) architectures, namely, single-hop networks with tunability provided only at the receiving side. We distinguish a number of multicast traffic types, we present a number of alternative broadcast/multicast timedivision multiple-access (TDMA) s...
متن کاملMulticast scheduling in WDM switching networks
Optical WDM networks are attracting more and more attentions because of its huge bandwidth to meet the ever increasing demand of modern networking applications. In this paper we study supporting multicast in WDM switching networks. Multicast is the operation to send information from one source to multiple destinations. In WDM switching networks, contention occurs when one output fiber is the de...
