“…In addition to separating the user and provider domain in IEEE 802.11ah, a new tag called I-SID, which can be used in place of the S-VID, was defined. The I-SID is 24 bits in length and has the potential of supporting millions of devices [15,19]. From our initial investigation this scale may be sufficient to support space applications.…”

The usage of satellite communication (SATCOM) resources by the Department of Defense (DOD) to deliver global IP-based services has increased dramatically in the last decade. The rapid growth in demand for IP-based application services in the DOD and the flexibility of information services in commercial communication networks are influencing the designs of the future DOD communication satellite systems. The emergence of the high-speed metro and carrier Ethernet technology in recent years has fueled the widespread interest from commercial service providers to deploy Ethernet as the next-generation metro area network (MAN) and potentially wide area network (WAN) transport technology. Ethernet technology utilizes spanning tree control protocol for initial network topology discovery and failure/recovery detection to provide network resiliency where the network can quickly establish an alternate path in the event of link device failure. Compared with terrestrial networks, the space-based networks are characterized by longer propagation delays. To establish a deeper understanding of Ethernet's control plane protocols and the performance implications when operating over a space-based network, we have developed a simulation capability that will analyze the protocol's operations and performance. In this paper, we will first present the feasibility of adapting Ethernet-based technology in space networks, then describe Ethernet's spanning tree protocol operations, and finally provide performance results of the protocol's convergence delay measurement.

“…Consequently, most transport networks are wireline except for high-speed point-to-point microwave radio systems. Typical transport networks comprise several layer networks using technologies such as multiprotocol label switching (MPLS) [RFC3031], asynchronous transfer mode (ATM) grade Ethernet to satisfy the higher operational requirements in an operator compared to an enterprise network [GPTV04,GPTB05,Med05,ABMR06]. Due to its frame-based transport, its aura as a cost-efficient solution, and the huge market potential for Ethernet-based transport services it can be expected to win a significant market share over the next years.…”

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...

SUMMARYThe transport network paradigm is changing as evidenced by IP convergence and the divergence of architectures and technologies. Harnessing the full power of light will spur the creation of new broadband and ubiquitous services networks. To attain this, however, not only must photonic technologies be optimized, but they must also be coordinated with complementary electrical technologies. With regard to photonic network design technologies, further developments are necessary including very large scale network design, quasi-dynamic network design, and multi-layer optical path network design. key words: photonic networks, photonic network design, multi-layer optical paths IntroductionBroadband access is penetrating throughout the world, and FTTH (Fiber to the Home) is being rapidly adopted in Japan and North America as the most powerful means of broadband access; there were more than six million users as of the middle of 2006 in Japan. Although this number is relatively small compared to ADSL (Asymmetric Digital Subscriber Line) subscribers (14.5 million), it continues to increase at a much higher rate than ADSL and is expected to exceed that of ADSL within a couple of years. Because of the rapid penetration of broadband access and the introduction of new services for businesses, the traffic of broadband users is increasing rapidly, i.e., more than 100 percent every year [1]. Considering further burst in the volume of traffic envisaged, which will be spurred by the penetration of bandwidth intensive new services based on video, another advances in network performance and cost reductions must be attained.In designing future networks and systems, we must consider the current paradigm changes; IP (Internet Protocol) convergence and the divergence of architectures and technologies. To start with, we discuss past and present status of network development in Sect. 2. Harnessing the full power of light will spur the creation of new broadband and ubiquitous services networks. The key requirements of enhancing the performance and reducing the cost of future IP-based multimedia communication networks can be effectively achieved by exploiting wavelength routing. This requires, however, not only the optimization of photonic technologies but also coordination with complementary electrical technologies. MPLS (Multiprotocol Label will also be needed. In Sect. 3, we discuss key issues that we need to consider in the development of the photonic network, and directions towards network throughput expansion. Finally, we discuss some of the cutting-edge photonic networking technologies including segmented network design, quasi-dynamic network design, multi-layer optical path network design, and optical fast circuit switching. IP Convergence and Technology Divergence Transport Network EvolutionFigure 1 depicts the trends in transport network evolution over the last two decades. At the middle of the 1980's, core and metro networks are based on the plesiochronous digital hierarchy (PDH) [5]. The digital hierarchy of Europe, Nort...
