Dimensioning of a multimedia switching bus

Abstract

A diverse set of networking technologies have been trialed in developing transport solutions for tomorrow S multimedia services. Due to the various objectives, those services are foreseen to be carried over multiparty networks, based on different transport technologies. Therefore, smooth service supply requires that operators support multiple transport systems or at least offer inter-connectivity between them. This means that parallel network nodes (e.g. switches) must be maintained for those network, which rises operational cost. A solution to lower the number of switches and networking cost is to combine different switching disciplines into a compact hybrid switch. A basic component for successive implementation of such a switch is the switching bus. Its interconnection architecture determines inherent capabilities cfthe system to fu@l the various requirements of multime,dia switching. This paper studies dimensioning and resource sharing mechanisms of shared bus architectures to apply them in multidiscipline switching.

Media Switch for Multimedia Services

“…2). The switch resources are permanently shared among the related systems and container dimensioning becomes a crucial issue [4,14].…”

“…FRS's performance has been analysed and compared to other interconnection networks, e.g., in [12] and [13]. Dimensioning of the FSR bus in multidiscipline environment has been analysed in [4] and [14].…”

Interworking Support in a Multi-Discipline Switch

“…A bridging solution, utilising FSR as the backbone technology for delivering multimedia services, is introduced in [12]. Dimensioning of the FSR bus in multidiscipline applications has been analysed in [3] and [13].…”

“…Interworking is performed on a higher level, so the bus itself does not need to know about possible interworking needs. The problem of allocating switching capacity for the parallel switching schemes and dimensioning of a ring shaped switching bus is discussed in [3,4,13].…”
