Switching, routing, active networking, service architecture The convergence of telecommunications, computing and content industries has been one of the major trends during the recent years. The convergence has lead to the creation of a wide range of multimedia services, which are available in digital form through broadband networks. There is a need for network nodes that are capable of interfacing to different kinds of networks and implementing a programmable service platform for multimedia services. As a solution to this need, this paper introduces the Media Switch, which is able to combine different switching disciplines into a compact fabric and provides a platform for multimedia services. Finally, example services based on the Media Switch prototype are presented.

“…This allows implementation of multiple virtual switches into a single fabric. FRS's performance has been analysed, e.g., in [9] and [10], and compared to other interconnection networks in [11]. A bridging solution, utilising FSR as the backbone technology for delivering multimedia services, is introduced in [12].…”

Interworking Support in a Multi-Discipline Switch

Broadband Communications

2000

The evolving multimedia services are foreseen to be delivered to customers over heterogeneous transport networks. The ATM technology has been considered as the most obvious choice, but other transporting concepts have also been studied and entirely new ones suggested, especially, for IP based communications. Diversity in transporting concepts implies that network nodes, such as switches and routers, should connect to different kinds of networks. This introduces the need to support multiple switching disciplines in a single switching fabric and, additionaIJy, a clear need for interworking. As a solution to the emerging problem, this paper introduces the concept of multidiscipline switching to integrate different switching systems into a compact fabric and to offer interworking between the connected networks.

“…Putting this all together gives the mean total service time in the common frame case as ( 6 ) f,""" a;;: = tswap + -R and in the super frame case as (7) n SUP = t f," a s r c swap + R Therefore, the total time spent in the system can be given in the common frame case by (see Eqs. 2 and 3) and for the traffic type n in the super frame case by where Performance of the destination release rings (e.g.…”

“…The experimented switching bus, the Frame Synchronised Ring (FSR) [7], is a slotted ring which utilizes destination release policy. FSR's performance has been analys'ed, e.g., in [6] and [7], and comparisons to other interconnection networks have shown competitive performance, especially, in ATM applications [7,8]. Powerful characteristics of FSR essential for implementing the demanding features of a multidiscipline switch include, e.g., inherent support :For real-time multicasting, versatile addressing capabilities and simultaneous switching of variable size data units.…”

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.
