“…The previous system we developed was not suitable for bi-directional transmission, and therefore, some static routing configuration is necessary. With that system, we achieved data transmission using TCP/IP or UDP/IP over optical packets at a speed of 80 Gbps [9], [21]. Moreover, signaling packets for lightpath setup are transferred in optical packets and are terminated at the optical integrated nodes for integration [21].…”

Moreover, signaling packets for lightpath setup are transferred in optical packets and are terminated at the optical integrated nodes for integration [21]. We achieved 170 km optical packet transmission including optical switching and buffering where three fiber-delay lines are incorporated and lightpaths are multiplexed with other wavelengths in the same optical fiber [22].…”

“…For this purpose, we obtain the number of packets transferred and the number of lightpaths established at every node. We integrate the network by sharing optical packet line among packet data, packet control information, and circuit control information [21].…”

SUMMARYThis paper presents recent progress made in the development of an optical packet and circuit integrated network. From the viewpoint of end users, this is a single network that provides both high-speed, inexpensive services and deterministic-delay, low-data-loss services according to the users' usage scenario. From the viewpoint of network service providers, this network provides large switching capacity with low energy requirements, high flexibility, and efficient resource utilization with a simple control mechanism. The network we describe here will contribute to diversification of services, enhanced functional flexibility, and efficient energy consumption, which are included in the twelve design goals of Future Networks announced by ITU-T (International Telecommunication UnionTelecommunication Standardization Sector). We examine the wavebandbased network architecture of the optical packet and circuit integrated network. Use of multi-wavelength optical packet increases the switch throughput while minimizing energy consumption. A rank accounting method provides a solution to the problem of inter-domain signaling for end-to-end lightpath establishment. Moving boundary control for packet and circuit services makes for efficient resource utilization. We also describe related advanced technologies such as waveband switching, elastic lightpaths, automatic locator numbering assignment, and biologically-inspired control of optical integrated network. key words: new generation network, optical packet switching, optical circuit switching, moving boundary

“…10(a) [5]. The integrated network provides both OPS links, which enable bandwidth-sharing and besteffort data transferring, and optical circuit switching (OCS) links, which enable a fully occupied bandwidth and endto-end QoS-guaranteed data transmission, based on common wavelength resources and fibers [40], [41]. By dynamically sharing wavelength resources between the OPS or OCS links [42], new or urgent services can be supported.…”

“…Recently, we have developed a primitive optical packet and circuit integrated network including one 2 × 2 integrated OPS/OCS node and a set of packet/lightpath transceivers. We successfully demonstrated 80 (8λ×10) Gbit/s colored optical packet and 8-lightpath switching and lightpath-establishment by transferring optical control packets over the OPS link [40], [41].…”

SUMMARYIn this paper, we show the recent progress of photonic network technologies for the new generation network (NWGN). The NWGN is based on new design concepts that look beyond the next generation network (NGN) and the Internet. The NWGN will maintain the sustainability of our prosperous civilization and help resolve various social issues and problems by the use of information and communication technologies. In order to realize the NWGN, many novel technologies in the physical layer are required, in addition to technologies in the network control layer. Examples of cutting-edge physical layer technologies required to realize the NWGN include a terabit/s/port or greater ultra-wideband optical packet switching system, a modulation-format-free optical packet switching (OPS) node, a hybrid optoelectronic packet switching node, a packet-based reconfigurable optical add/drop multiplexer (ROADM) system, an optical packet and circuit integrated node system, and optical buffering technologies. key words: new generation network, optical packet switching, optical packet and circuit integrated network, transparent switching, burst-mode devices

We are developing an integrated optical packet-and circuit-switched network. In this paper, we feature our own control system of the network and experimentally evaluate its performances. In our experimental setup, both best-effort data and control signals are transferred on colored (i.e. multi-wavelength) optical packet-switched links. We successfully transmit high-definition uncompressed real-time video signals on two lightpaths established by our control system without degradation of video quality, while other packet data are transferred in the same optical fibers. The developed system also has a function of adaptive resource change of packet switching and circuit switching. Time distances for resource change and lightpath setup are negligible, and therefore users do not feel stress for path establishment as the following results prove. Controller PCs can achieve lightpath establishment and automatic resource-allocation within approximately 500ms and 830ms, respectively, at the best possible case in our experimental setup.
