WDM Multicasting in IP over WDM Networks
Supporting WDM multicasting in an IP over WDM network poses interesting problems because some WDM switches may be incapable of switching an incoming signal to more than one output interface. An approach to WDM multicasting based on wavelength-routing, which constructs a multicast forest for each multicast session so that multicast-incapable WDM switches do not need to multicast, was proposed an...
متن کاملOptical Wdm Networks and Multicasting
Bandwidth usage increases day by day and the need for new technologies emerges for devoloping the efficiency. Wavelength Division Multiplexing (WDM) is the most spectacular one of these presented network technologies to be able to use optical fibers. In addition to that, multicasting the network traffic also draws attention for ensuring the growing traffic demand. In multicasting, the transmiss...
متن کاملMulticasting and Broadcasting in Large WDM Networks
We address the issue of multicasting and broadcasting in wide area WDM networks in which a source broadcasts a message to all members in S ( V ). We formalize it as the optimal multicast tree problem which is de ned as follows. Given a directed network G = (V;E) with a given source s and a set S of nodes, jV j = n and jEj = m. Associated with every link e 2 E, there is a set (e) of available wa...
متن کاملMulticasting 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...
متن کاملTraffic Groomed Multicasting in Sparse-Splitting WDM Backbone Networks
As the interest of the Internet multicasting increases, the huge portion of the future traffic in optical WDM networks is expected to be strongly related to multicast applications and thus the technology for grooming such traffics also becomes important. In this study, we investigate the problem of multicast traffic grooming in WDM optical mesh networks with sparse-splitting capability. The pro...
