Abstract:
We propose a new architecture of dynamic time-wavelength division multiplexing-passive optical network (TWDM-PON) system that employs integrated all-optical packet routing (AOPR) module using4λ×10 Gbps downstream signal to support 20 km fiber transmission. This module has been designed to support high speed L2 aggregation and routing in the physical layer PON system by using multicasting cross-gain modulation (XGM) to route packet from any PON port to multiple PON links. Meanwhile, the fixed wavelength optical line terminal (OLT) transmitter with wavelength tuning free features has been designed to integrate with the semiconductor optical amplifier (SOA) and passive arrayed waveguide grating (AWG). By implementing hybrid multicasting and multiplexing, the system has been able to support a PON system with full flexibility function for managing highly efficient dynamic bandwidth allocation to support the4λ×10 Gb/s TWDM-PON system used to connect 4 different PON links using fixed wavelength OLT transceivers with maximum 38 dB link loss.

Abstract:
We study the blocking probability and performance of single-fiber and multifiber optical networks with wavelength division multiplexing (WDM). We extend the well-known analytical blocking probability model by Barry and Humblet to the general model, which is proposed for both single-fiber and multifiber network paths with any kind of wavelength conversion (no, limited, or full wavelength conversion) and for uniform and nonuniform link loads. We investigate the effect of the link load, wavelength conversion degree, and the number of wavelengths, fibers, and hops on blocking probability. We also extend the definition of the gain of wavelength conversion by Barry and Humblet to the gain of performance, which is fully general. Thanks to this definition and implementation of our model, we compare different WDM node architectures and present interesting results.

The exchanged crossed cube, denoted by [Formula: see text], is a novel interconnection network with fewer edges and smaller diameter compared to other variations of the corresponding hypercube. The linear array, denoted by [Formula: see text], is one of the most popular topologies in optical networks. This paper addresses the routing and wavelength assignment for realizing [Formula: see text] communication pattern on wavelength division multiplexing (WDM) optical network [Formula: see text], where [Formula: see text]. We prove that the congestion for [Formula: see text] on [Formula: see text] is equal to [Formula: see text], which is the lower bound of the minimum number of required wavelengths. In addition, an embedding scheme and an optimal wavelength assignment algorithm that achieve this bound are also proposed.

Abstract:
Radio over fiber (RoF) techniques are good candidates to create the backbone of the next generation of wireless networks. Many parameters affect RoF communications such as amplified spontaneous emission noise (ASE), four-wave mixing nonlinearity (FWM), the modulation, channel spacing, switching voltage, and phase shifter. In this paper, we propose an improved model of RoF communication systems using subcarrier multiplexing/wavelength division multiplexing (SCM/WDM) technique with unequal channel spacing and 1-km Erbium-doped fiber amplifier (EDFA). Simulation results confirmed that we could obtain the lowest bit error rate and noises when the EDFA is placed at 1 km from the transmitter by using optical single-sideband (OSSB) modulation at frequencies 193.1 THz, 193.2 THz, 193.35 THz, and 193.6 THz.

Abstract:
Optical Burst Switching (OBS) is one of the most important switching technologies for future IP over wavelength division multiplexing (WDM) networks. In OBS Network, the burst assembly technique is a challenging issue in the implementation of the system. Burst assembly influences burst characteristics, which negatively impacts network performance. In this paper, the authors propose an efficient hybrid burst assembly approach, which is based on approximate queuing network model. To reduce the time complexity, an approximate queuing network model has been considered. Throughput performance has been investigated, taking into account both burst loss probability and time complexity. Simulation results have shown that the proposed hybrid approach based on variable burst length threshold and fixed maximum time limitation provides Simulation results have also shown a good trade-off between burst blocking performance and scheduling time.

Abstract:
We address the problem of allocating optical bandwidth to a set of communication requests in a tree-shaped all-optical network that utilizes Wavelength Division Multiplexing (WDM) technology. WDM technology establishes communication between pairs of nodes of the network by establishing tranceiver–receiver paths and assigning wavelengths to each path so that no two paths going through the same link use the same wavelength. Optical bandwidth is the number of distinct wavelengths. The important engineering problem to be solved is to establish communication between pairs of nodes so that the total number of wavelengths used is minimized. In this paper, we focus on a special case of the problem considering patterns of requests that are symmetric, i.e. for any transmitter–receiver pair of nodes (v1, v2) there also exists its symmetric (v2, v1). Our motivation lies in the fact that many services that are expected to be supported by high performance optical networks in the future, require bidirectional reservation of bandwidth. We prove that the problem of optimizing the number of wavelengths used is NP-hard even when the underlying network is a binary tree. We also present two interesting lower bounds.

Abstract:
Recently, metropolitan and access communication networks have markedly developed by utilizing a variety of technologies. Their bearer communication infrastructures will be mostly exploiting the optical transmission medium where wavelength division multiplexing techniques will play an important role. This contribution discusses the symmetric sharing of common optical network resources in wavelength and time domains. Wavelength-Division Multiplexed Passive Optical Networks (WDM-PON) attract considerable attention regarding the next generation of optical metropolitan and access networks. The main purpose of this contribution is presented by the analysis of possible scheduling of wavelengths for our novel hybrid network topologies considered for WDM-PON networks. This contribution briefly deploys adequate Dynamic Wavelength Allocation (DWA) algorithms for selected WDM-PON network designs with the provision of traffic protection when only passive optical components in remote nodes are utilized. The main part of this study is focused on the use of wavelength scheduling methods for selected WDM-PON network designs. For evaluation of offline and online wavelength scheduling for novel hybrid network topologies, a simulation model realized in the Matlab programming environment allows to analyze interactions between various metropolitan and access parts in the Optical Distribution Network (ODN) related to advanced WDM-PON network designs. Finally, wavelength scheduling methods are compared from a viewpoint of utilization in advanced WDM-PON networks designs.

Abstract:
In optical networks the approach called wavelength division multiplexing allows multiple data streams to be transmitted concurrently along a single optical link, with different streams assigned separate wavelengths. In this paper we refer to all-optical networks, in which each connection is totally optical except at the terminal nodes. For these networks we determine the minimum possible number of links required to perform a fault tolerant broadcast from any node, in terms of the number of nodes, the number of link failures to tolerate and the number of wavelengths to use. We also give lower and upper bounds on the number of wavelengths required for any broadcast which tolerates a given number of link failures on networks with arbitrary topologies.

Abstract:
In this paper, we propose a new media access protocol for single hop Wavelength Division Multiplexing (WDM) networks with a passive star topology. In the conventional protocols, when the control packets collided with other ones or the packets didn't get a data channel from the channel reservation mechanism, these packets should be retransmitted. But, when transmission distance becomes long, it takes a long time to transmit the control packets and the propogation dalay time will be long. We propose a new protocol that can allocate data channels without retransmitting control packets except the collided ones. By using the proposed protocol, it is possible to reduce the transmission delay time and to get high throughput because the number of retransmitted control packets is reduced. The simulation results show that the proposed protocol has good performance comparied with conventional protocols.
