01 Dec 2003TL;DR: This paper proposes an inter-domain dynamic routing scheme with modest time complexity to address the problem of inter- domain dynamic routing under a multi-layer multi-domain network model.
Abstract: Next-generation optical transport networks will automatically and dynamically provision end-to-end connections. In this paper, we study the problem of inter-domain dynamic routing under a multi-layer multi-domain network model, which allows the end-to-end connections to be set up not only across multiple routing domains but also through two transport layers: the optical layer and the digital layer. In this model, a connection can traverse the domain boundary either through optical bypass or through optical-electrical-optical (O/E/O) processing. We propose an inter-domain dynamic routing scheme with modest time complexity to address the problem from an algorithmic perspective.

TL;DR: To support optical multiprotocol label switching (MPLS) technology in an optical network, subcarrier label swapping is demonstrated in a 96.2 km, three-node experiment, by using optical single-sideband modulation and an optical notch filter.
Abstract: To support optical multiprotocol label switching (MPLS) technology in an optical network, we have demonstrated subcarrier label swapping in a 96.2 km, three-node experiment, by using optical single-sideband modulation and an optical notch filter. At each intermediate switching node, an old subcarrier label can be suppressed by 25 dB, while the 2.5 Gb/s payload experienced only 2 dB loss.

TL;DR: In this paper, a novel in-service live fiber-to-the-home (FTTH) passive optical networks (PONs) management solution uses a modified direct-sequence (DS) optical code-division multiplexing (OCDM) system and overcomes the optical time-domain reflectometry (OTDR) point-tomultipoint shortcomings.
Abstract: Feature Issue on Optical Code Division Multiple AccessWe propose, to the best of our knowledge, a novel in-service live fiber-to-the-home (FTTH) passive optical networks (PONs) management solution. Our solution uses a modified direct-sequence (DS) optical code-division multiplexing (OCDM) system and overcomes the optical time-domain reflectometry (OTDR) point-to-multipoint shortcomings. Our solution addresses various service provisioning and network maintenance challenges in PONs, alleviates their complexity, and reduces their operational cost. In addition, our system exploits passive devices (or encoders) to demark service provider ownership and responsibility from that of customers. Our OCDM-based management solution easily scales up from FTTH time-division multiplexing (TDM)-PON to WDM-PON and TDM/WDM-PON to support as many as a thousand customers, all using only one monitoring wavelength. We address the coding system and develop capacity curves for different PON scenarios.

TL;DR: It is shown how single-hop and multihop wavelength-routed networks can be used efficiently for fast end-to-end file transfers when these networks are equipped with a hardware-implementable signaling protocol, a routing protocol, and a simple transport protocol.
Abstract: This article first discusses how advances in networking architectures and protocols can complement advances in optical communications research to increase the overall value of optical networks by enabling more applications. A review of existing optical networking solutions is then provided along with a classification of different types of optical networks. Finally, we show how single-hop and multihop wavelength-routed networks can be used efficiently for fast end-to-end file transfers when these networks are equipped with a hardware-implementable signaling protocol, a routing protocol, and a simple transport protocol.

TL;DR: This work demonstrates the loading and unloading of a compensating optical fiber loop buffer storing packets of 40-Gb/s data for over 300 circulations.
Abstract: Ultrafast slotted, time-division-multiplexed (TDM) multiaccess networks will utilize optical buffers at user nodes to hold data packets until they are transmitted and to hold received packets until they are demultiplexed or rate converted. We demonstrate the loading and unloading of a compensating optical fiber loop buffer storing packets of 40-Gb/s data for over 300 circulations.
