The video signal is encoded hierarchically into a number of layers with the first layer containing the essential information such that the least capable receivers can reconstruct the video signal with lower quality. Each of the higher layers contains information which can further enhance the quality of the video signal. The cost associated with a network link is dependent on the number of layers of video signal it is carrying. The nodes in the network may be allowed to join or leave the multicast connection dynamically for some network applications. The problem is to find a path to attach a node which wishes to join the multicast connection to the existing multicast tree such that a certain performance measure is optimized. Two heuristic algorithms, namely, shortest path minimum additional cost (SP-MAC) and minimum additional cost (MAC) algorithms are proposed for this problem. The performances of the proposed algorithms are compared with those of the shortest path and dynamic greedy algorithms by extensive simulations. Our results show that the proposed algorithms outperform the shortest path and dynamic greedy algorithms.","PeriodicalId":414137,"journal":{"name":"IEEE GLOBECOM 1998 (Cat.

Huang, Yao-Tzung Wang, Bo Li, Te-Lung Liu","doi":"10.1109/GLOCOM.1998.775753","DOIUrl":"https://doi.org/10.1109/GLOCOM.1998.775753","url":null,"abstract":"Future broadband networks must support integrated services and offer flexible bandwidth usage. Most existing proposals for wide-area wavelength division multiplexed (WDM) networks employ circuit switching adopting the concept of lightpath, in which each circuit or lightpath occupies an entire wavelength. This, however, is not suited for end-to-end transport of information streams, typically with each stream having its unique traffic characteristics such as the bandwidth needed, different traffic bursty nature, and diverse service requirements. We explore the extensions of the functions of what we refer as the optical link control (OLC) layer, native on top of optical layer, to offer finer granularity of wavelength usage and further enable the possibility of bandwidth on-demand (BoD) service directly over WDM networks. The objective is to facilitate the support of integrated services over WDM networks and to mitigate the changes needed in the upper layers as well. The proposed approach attempts to exploit the strengths of both optics and electronics, in which packets are either routed end-to-end over a lightpath transparently, or forwarded from wavelength to wavelength by electronic switching, whenever required. Furthermore, in order to establish an end-to-end BoD connection, the issue of how to select the best wavelength to route the given connection is also investigated. The effectiveness of the proposal is evaluated by simulation.","PeriodicalId":414137,"journal":{"name":"IEEE GLOBECOM 1998 (Cat.
