“…Therefore, multi-layer or cross-layer design and engineering are actively worked on in several areas of communications. In transport networks, multi-layer traffic engineering and resilience attempt to optimally exploit the specific granularities and dynamics of the different network technologies [Mod01,Cin03,NGB03,VPD04,Köh05b,OM05,ZZM05]. In wireless communications, architectures and protocols on different layers are mostly adapted to match the special characteristics of radio transmission links, e.g., high packet losses or transfer delays [KHFK05,KHFK06].…”

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...

“…The TE algorithm implemented is called Weighted Integrated Routing (WIR) and was proposed in [19]. It assumes a co-location of the electrical and optical nodes and operates in a two-step approach: the first step includes a shortest path search from source to destination; the second step chooses a subset of intermediate nodes and checks the feasibility of a path using these nodes.…”

A new efficient integrated routing scheme for SDH/SONET-WDM multilayer networks

Abstract: This paper presents and evaluates the new Weighted Integrated Routing scheme to solve the problem of dynamic routing and traffic grooming in meshed SDH/SONET-WDM multilayer networks. Its performance is compared to non-integrated schemes using a cost model.
