“…So a commercial manual variable delay line is enough. Besides, the Multi-Wavelength OPS proposed recently [11] [12] also makes it possible for slotted OPS to support variable packet length. So we think slotted OPS with NGC nowadays is a good substitute for asynchronous OPS.…”

Abstract-Optical buffering is one of the main obstacles in optical packet switching (OPS) networks. We proposed the network global control strategy to resolve this problem. By introducing the cycled traffic at the edge node and the slot assignment algorithm at the core node, a slotted OPS networks with no contention can be realized. In this network, a good throughput, end to end delay and delay jitter performance can be gotten at high load simultaneously, so it may be a promising candidate for the future optical networks.

“…In addition to that, the utilization of wavelengths is low when the number of packets towards the same edge node does not reach the number of the wavelengths within defined time period. The feasibility of the multi-wavelength OPS network with this method has been confirmed by Onaka et al [6]. Their node architecture was based on broadcast-and-select switch which consists of SOA switches with multistage configuration.…”

“…The feasibility of the multi-wavelength OPS technology has been confirmed with Semiconductor Optical Amplifier (SOA) switch and LiNbO 3 (LN) switch [6,8]. However, it has never been confirmed with a PLZT switch which has the capabilities of fast switching, low noise, polarization independency, and low drive voltage.…”

“…Currently two methods of the composition have been proposed: 1) the payload contains multiple packets of upper layer protocols [6], and 2) the payload contains one packet of upper layer protocols [7] as illustrated in Fig.3 and Fig.4 respectively. With the former method, incoming packets of upper layer protocols are buffered at an ingress edge node for defined time period.…”

Abstract. This paper proposes 80Gb/s multi-wavelength optical packet switching(OPS) using a PLZT switch. The Multi-wavelength OPS Network can achieve low implementation costs compared to existing OPS networks in which the number of wavelengths is large. In this network, the header is processed separately from the payload. The payload is divided into multiple segments. Each segment is then encoded into different wavelengths. After assignment of wavelength to each payload segment, payload segments are multiplexed into an optical signal which is then transmitted through an optical fiber. Therefore, the number of components required for intermediate node functionality stays the same for the number of wavelengths used for payload transmission. This paper shows a fundamental experiment of the Multi-wavelength OPS network using a PLZT switch. PLZT switch provide a fast optical switching with low noise, independent polarization, and low drive voltage. In this paper, we describe the detail of the experiments and results.

“…One of the big issues facing realization of such interconnection systems is the huge amount of interconnecting elements, especially switches, cables, and OE/EO modules. In the proposed network archtecture [7], an electric leaf switch is used for the switching of the intra-rack signals and the aggregation of the inter-rack signals by using packet queues for high bandwidth data interconnection. The aggregated signals are converted to optical packet signals and interconnected by the optical spine switch among computing node groups under the control of the arbiter.…”

Abstract. Government-funded R&D initiatives have been playing crucial roles for developing photonic networks. The R&D project is typically carried out for a relatively long period of five-years, and the goal is set so high that no single private sector can afford the risk. In this paper, challenging governmentfunded R&D initiatives of photonic networks in Japan is introduced. They have been launched in 2006, which aims to establish the photonic platform to provide abundant bandwidth on demand, at any time and from anywhere, to promote bandwidth-rich networked applications. In addition, other governmentfunded R&D activities relevant to the photonic networks in Japan is also presented, including photonic devices and subsystems and large-scale optical interconnect for ultra-high performance computing.
