“…Test-beds have been set up to demonstrate the feasibility of Optical Burst Switching (OBS) paradigm with a variety of switching devices [5, 6, 7 , 8, 9]. Performance evaluation of hybrid optical switches has been carried out [10,11,12,1] and the hybrid approach has been compared with the use of a single technology [13,14]. Furthermore, an initial design analysis of architectures for MG-OXe has been undertaken [15], and it has been shown that the performance of hybrid architectures is little different from that of switches equipped with fast technology only, while the cost and scalability of the hybrid approach are superior.…”

This paper presents a programmable multi-granular optical cross connect (MG-OXC) and network architecture deployable in multi-service and multi-provider networks . The concept of programmable MG-OXC is introduced to provide a way of utilizing multiple switching/transport granularities to efficiently support the emerging traffic demands in both core and metro networks. For this reason, the supported bandwidth granularities include full lambdas, sub-and super-lambdas and multiple transport formats such as bursts, flows and packets. The programmability is envisaged by a software/hardware platform that simplifies network control, re-planning at the logical level and end-to-end service transparency, by translating the technology-specific information to technology independent services in an abstracted and logical manner.

“…1 Optical bursts with the same multiplexing/demultiplexing core node would not have to be switched in intermediate core nodes but could be transported together through the WSN in a direct lightpath instead as also illustrated in Figure 4.2. Such an interconnection of burst-switched nodes with direct lightpaths is also proposed in [OSHT01,CSBO03] as an OBS/OPS introduction scenario (cf. Section 2.3.4) and referred to as burst-over-circuit-switching (BoCS) here.…”

SummaryTransport networks form the backbone of communication networks by cost-efficiently offering huge bandwidth and by guaranteeing a high service quality and availability. These requirements can best be met by using optical communication technologies. Currently, wavelength-switching is the most prominent network technology employing optical fiber communication and wavelength division multiplexing. It transports data in circuit-switched wavelength channels, the so-called lightpaths. While for years progress in optical networks has been defined by ever increasing transmission bit-rates, higher flexibility and manageability as well as multi-service and multi-layer integration are equally important criteria today. Accounting for these trends, optical burst switching (OBS) has been proposed as a highly dynamic optical network architecture. It offers fine-granular transport of different packet-switched services and applies statistical multiplexing directly in the optical layer.This thesis presents the design, modeling, and evaluation of the optical burst transport network architecture (OBTN). The architecture is motivated by the need for flexible, scalable, and cost-efficient transport in next generation networks. In addition, it is stimulated by the research activities towards highly dynamic optical network infrastructures.OBTN defines a network architecture to transport and switch optical burst data in a core network. The design objectives for the OBTN architecture are (i) an overall high quality of service, (ii) a network design allowing for cost-efficiency and scalability, and (iii) a network evolution perspective based on the current wavelength-switched networks. These objectives are achieved by combining selected concepts, architectures, and strategies of optical burst and optical packet switching as well as of multi-layer traffic engineering.In order to provide the background information for the design of OBTN, Chapter 2 introduces the general characteristics, requirements, and trends for next generation transport networks. Also, it discusses the concept of layering in next generation networks and its application in layer networks for the virtualization of transport resources. Consequently, virtual topology design and dimensioning are analyzed to quantify the trade-offs regarding connectivity and resource requirements. Chapter 2 also reviews the fundamental technologies as well as currently emerging data and control plane architectures for optical transport networks. This presentation is then extended towards a long-term perspective. It describes architectural constraints and classification criteria for highly dynamic optical network architectures. These criteria are used to characterize the fast optical circuit switching, optical burst switching, and optical packet switching architectures. Then, hybrid optical network architectures are discussed as a framework to combine wavelength-switched and optical burst/packet-switched networks.i ii Summary Chapter 3 discusses the state of research and technology for o...
