The optical Internet: architectures and protocols for the global infrastructure of tomorrow

Abstract: We present a high-level overview of the current state of the network architectures, protocols, and technologies that will serve as the seed for the optical Internet. We further propose that a two-way ripple effect of technologies penetrating from the edge to the core and vice versa, and the associated transformations that result, represent the keys to unlock the full potential of an optical Internet.

Cost Minimization Planning for Passive Optical Networks

Abstract: We plan PON network deployment to minimize its total cost. An efficient heuristic is proposed, which can reduce 50%~70% PON network deployment costs compared to a benchmark sectoring approach.

Bandwidth allocation for service level agreement aware Ethernet passive optical networks

Abstract: Passive optical networks (PON) are thought to be the next step in the development of access networks and providing broadband access in the "last mile" area. Ethernet PON (EPON) are gaining the most attention from industry as they offer a highly flexible, cost effective solution. In this paper, we present a new approach to the problem of optimal bandwidth allocation in EPON. We show that by moving all the access control functionality to the optical line terminator, a flexible solution could be achieved which offers full support for service level agreements and removes the burden of managing the configuration of every optical network unit. We include results of simulations that show that such an approach can deliver good performance in terms of average and maximum packet delay. We show that a novel Grant multiplexing scheme can significantly reduce jitter and end-to-end delay experienced by the high priority classes of traffic. To prove these points we present results of detailed experiments that were run on a C++ event driven simulator, that we have developed.

Architecture and applications of a versatile small-cell, multi-service cloud radio access network using radio-over-fiber technologies

Abstract: Small-cell systems based on cloud radio access network (cloud-RAN) architecture have been proposed as promising solutions to meet the ever-increasing capacity demand of the next-generation wireless access networks. By centralizing the processing power to reduce the complexity of conventional cell sites, the cloud-RAN architecture is ideal for large-scale small-cell system at reduced capital and operational expenses. However, high-speed, flexible, and scalable backhaul links between the centralized baseband processing unit (BBU) and the remote antenna units (RAUs) are required to support the high throughput of the small-cell cloud-RANs, and the conventional approaches are based on digital baseband signal transmission in the backhaul links. In this paper, we propose a novel multi-service small-cell wireless access architecture based on radio-over-fiber (RoF) technologies. By utilizing analog radio frequency (RF) signal transmission in the optical backhaul links, the design of RAUs can be further simplified. In addition, by combing RoF with optical wavelength division multiplexing (WDM) techniques, multiple bands, multiple services and multiple operators can coexist in a shared optical infrastructure without interference. To demonstrate the proposed system, two-operator coexistence in a shared small-cell cloud-RoF access network is implemented in an in-building testbed by using off-the-shelf optoelectronic components and commercialized WiMAX base stations and clients. In addition, the feasibility of delivering both conventional wireless services and future-proof high-RF-band services (millimeter-wave band) is also demonstrated in the proposed multi-service small-cell cloud-RoF access systems.
