TL;DR: Evaluations show that the multi-flow (MF) transponder-based elastic optical network architecture is superior to two other architectures in terms of scalability of optical nodes and network costs.
Abstract: The elastic optical network has proven to be a promising network architecture for handling the rapid growth in IP traffic in the optical layer in a spectrum-efficient manner. This study reveals the optical node requirements in elastic optical networks by comparing multiple network architectures using an integrated resource allocation scheme that considers both network and node parameters. Evaluations show that the multi-flow (MF) transponder-based elastic optical network architecture is superior to two other architectures in terms of scalability of optical nodes and network costs.

Abstract: Nowadays, fiber-based access networks are considered to be a major solution to provide the triple-play (voice, video and data) services. However, telecom companies are forced to provide a cost effective solution due to the rapid technological evolution and fierce competition. Return on investment for the deployment of Greenfield networks or transformation of existing legacy networks need to be maximized. In addition, the network should be designed in such a way that it is easy to deploy and to maintain. To achieve these objectives, an intelligent network planning system is required to minimize the cost of network design with the practical considerations to alleviate the future maintenance. In this paper, we provide an approach that uses road information in order to tackle the FTTH access network planning problem with the focus on handling practical scenarios.

TL;DR: A new layered transport network architecture on which the WDM optical path network can be effectively created is proposed that retains maximum commonality with the layered architectures developed for existing B-ISDN networks.
Abstract: This paper proposes a new layered transport network architecture on which the WDM optical path network can be effectively created. The optical path network will play a key role in the development of the transport network that will realize the bandwidth-abundant B-ISDN. This paper extends the layered transport network architecture described in ITU-T Recommendation G.803 which is applied in existing SDH networks. First, we elucidate an application example of WDM optical path networks. Next, we propose a new layered architecture for WDM-based transport networks that retains maximum commonality with the layered architectures developed for existing B-ISDN networks. The proposed architecture is composed of circuit layer networks, electrical path layer networks, optical layer networks, and physical media (fiber) networks. The optical layer is divided into an optical path layer and an optical section layer. The optical path layer accommodates electrical paths. Optical section layer networks are divided into optical multiplex section (OMS) layer networks and optical repeater section (ORS) layer networks. The OMS layer network is concerned with the end-to-end transfer of information between locations transferring or terminating optical paths, whereas the ORS layer is concerned with the transfer of information between individual optical repeaters. Finally, a detailed functional block model of WDM optical path networks, the function allocation of each layer, and an optical transport module (OTM) are developed.

TL;DR: The problem of designing this adaptation layer and of dimensioning the optical slot size in IP/MPLS over optical packet switched networks is addressed.
Abstract: Current optical technology allows an easy implementation of synchronous, time-slotted optical networks. In contrast, traffic in electrical domain (for instance IP) mainly consists of asynchronous, variable length packets. Therefore a packet format adaptation process is needed between electrical and optical domains, the optical slot size being in this process a crucial parameter, which strongly influences the bandwidth utilisation and determines the overall network performance. In this paper we address the problem of designing this adaptation layer and of dimensioning the optical slot size in IP/MPLS over optical packet switched networks. Three different optical packet formats, namely fixed-length packet, slotted variable-length packet, and fixed-length packet with traffic aggregation are discussed. To find the optimum size, the efficiency of such formats are evaluated by simulations.
