“…Therefore, instead of constructing a complicated and timeconsuming scheduling mechanism, we previously proposed simple, yet efficient, two-phase multicast mechanisms, lookback queue access (LBQA) [11,12], lookback ratio access (LBRA), and double check head access (DCHA) [13] to be employed in the central scheduler for a real-time implementation. The essence of these proposed algorithms is described as follows: In phase 1, the scheduler searches for a candidate multicast packet that can be sent, without partition, to all of their intended recipients.…”

In this article, we propose three multicast scheduling mechanisms, lookback queue access, lookback ratio access, and double check head access, for the employment in the single-star Wavelength Division Multiplexing optical network. Each of the proposed scheduling schemes consists of two phases and is executed in real time. In general, the first phase is to search for a candidate multicast packet that can be sent, without partition, to all of its intended recipients. If phase 1 fails, the second phase is then activated to partition a multicast packet into multiple transmissions in accordance with specific criteria of each individual mechanism. These algorithms are designed to mitigate the head-of-line blocking effect, while at the same time achieving excellent network throughput levels and delay performance via the partitioning procedure. Performance results reveal the distinct features of each mechanism under various scenarios. For a wider range of networking environments, we further propose an interconnected dual-star structure and enhanced multicast scheduling algorithms. These enhanced schemes aim to exploit the inter-data channels efficiently and utilize the wavelength reuse property of the intra-data channels properly. Performance results have demonstrated the merits of deploying the proposed multicast algorithms in such a dual-star structure.

Optical technology gains extensive attention and ever increasing improvement because of the huge amount of network traffic caused by the growing number of internet users and their rising demands. However, with wavelength division multiplexing (WDM), it is easier to take the advantage of optical networks and optical burst switching (OBS) and to construct WDM networks with low delay rates and better data transparency these technologies are the best choices. Furthermore, multicasting in WDM is an urgent solution for bandwidth-intensive applications. In the paper, a new multicasting protocol with OBS is proposed. The protocol depends on a leaf initiated structure. The network is composed of source, ingress switches, intermediate switches, edge switches, and client nodes. The performance of the protocol is examined with Just Enough Time (JET) and Just In Time (JIT) reservation protocols. Also, the paper involves most of the recent advances about WDM multicasting in optical networks. WDM multicasting in optical networks is given as three common subtitles: Broadcast and-select networks, wavelength-routed networks, and OBS networks. Also, in the paper, multicast routing protocols are briefly summarized and optical burst switched WDM networks are investigated with the proposed multicast schemes.

Widely available broadband services in the Internet require high capacity access networks. Only optical networking is able to efficiently provide the huge bandwidth required by multimedia applications. Distributed applications such as Video-Conferencing, HDTV, VOD and Distance Learning are increasingly common and produce a large amount of data traffic, typically between several terminals. Multicast is a bandwidth-efficient technique for one-to-many or many-to-many communications, and will be indispensable for serving multimedia applications in future optical access networks. These applications require robust and reliable connections as well as the satisfaction of QoS criteria. In this chapter, several access network architectures and related multicast routing methods are analyzed. Overall network performance and dependability are the focus of our analysis.
