“…In [7], Baldine et al realized an OBS testbed using MEMS OXCs from ATDnet. In [8,9], NTT and Fujitsu demonstrated burst switching with GMPLS-based two-way signaling protocol, utilizing planar lightwave circuit (PLC) and MEMS switches. In [10], commercial PLC switches were adopted to construct a 1616 non-blocking switch matrix with a switching speed of less than 3 ms. OBS schemes with hybrid optical and electrical switching technologies have been investigated in the past [11].…”

Abstract-A fundamental issue in all-optical switching is to offer efficient and cost-effective transport services for a wide range of bandwidth granularities. This paper presents multi-granular optical crossconnect (MG-OXC) architectures that combine slow (ms regime) and fast (ns regime) switch elements, in order to support optical circuit switching (OCS), optical burst switching (OBS), and even optical packet switching (OPS). The MG-OXC architectures are designed to provide a cost-effective approach, while offering the flexibility and reconfigurability to deal with dynamic requirements of different applications. All proposed MG-OXC designs are analyzed and compared in terms of dimensionality, flexibilityÕ reconfigurability, and scalability. Furthermore, node level simulations are conducted to evaluate the performance of MG-OXCs under different traffic regimes. Finally, the feasibility of the proposed architectures is demonstrated on an application-aware, multi-bitrate (10 and 40 Gbps), end-to-end OBS testbed.

“…Two way signaling is used to guarantee burst transmission, and GSMP (General Switch Management Protocol) is utilized. After receiving a GSMP request command, optical switch control is completed within 4 ms, and the GSMP acknowledge command is returned within 6 ms. A 10 Gbps burst transmission experiment (burst lengths ranged from 100-300 ms) with a switching time of less than 30 ms has been successfully demonstrated using a 6-node network [80]. The application area of fast circuit switching with distributed signaling is limited to a certain geographical area such as LANs and MANs due to the circuit establishment time (processing time at each node plus transmission delay) which determines the maximum usage of links.…”

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...

“…So far there have been several reports of optical burst switching using ms order switches and one/two way signaling [3]; however for real time applications latency of ms-order can be detrimental. Many trials of ns-sized optical packet switching are reported [2], but these schemes usually require optical variable buffer memory to avoid contention, which is still an immature technology.…”

An optical burst switching (OBS) node with a fast 4x4 PLZT (Lead Lanthanum Zirconate Titanate) optical matrix switch and an electronic label processor is presented. Successful collision detection and collision resolution is demonstrated by two methods: deflection routing and shared wavelength conversion. Error-free performance at 10 Gbps payload was achieved for both. Switching speed of 3.5 µs was achieved, demonstrating small data granularity in the order of 10 µs.
