Next-generation PON-part I: Technology roadmap and general requirements

PON Convergence

“…Use the Home tab to apply title to the text that you want to appear here. 3 process where even idle circuits consume significant power due to their leakage current, and because the amount of circuitry (gate count) is certainly going to scale at least with the data rate, and probably even faster than that.…”

“…The development of passive optical network (PON) systems has resulted in two families of standards being written by various groups [1][2][3][4][5]. The ITU-T PON systems are defined primarily in ITU-T recommendations, which cover the system, physical medium dependent (PMD), transmission convergence (TC), and management layers.…”

A Research Framework for the Clean-Slate Design of Next-Generation Optical Access

“…The recent introduction of high-performance computing (HPC) clusters and the cloud computing [22], however, brings enormous computing power at a much lower cost and, in case of the cloud computing, on-demand basis; this enables researchers to carry out a series of large-scale network simulations in a realistic environment, which was neither practical nor economically feasible in the past. Specifically, we are using Amazon elastic compute cloud (Amazon EC2) 4 as a running platform for the virtual test bed, while we are developing programs at a local HPC cluster for ease of testing and debugging processes. Fig.…”

“…In addition to HTTP and FTP traffic, we also implemented a high-rate, HD-TV-quality streaming video traffic for the virtual 3 The implemented simulation models are available at "http://github.com/kyeongsoo/inet-hnrl". 4 http://aws.amazon.com/ec2/ test bed, which is considered one of killer applications for the NGOA. The implemented traffic module can generate frames based on trace files from the ASU video trace library [26].…”

“…While investigating the issues of quality of experience (QoE), elasticity 1 , and energy efficiency in next-generation optical access (NGOA) as part of research programs since 2009 [1], [2], [3] with a major focus on the solutions beyond 10-Gbit/s Ethernet passive optical network (10G-EPON) and 10-Gigabit-capable PON (XG-PON) (e.g., NG-PON2 [4] by ITU-T), we have noted that the progress in the clean-slate design of NGOA is impeded by the absence of a comprehensive research framework for a comparative analysis of candidate network architectures and protocols. In fact, many NGOA network architectures have been proposed by both academia and industry and are now under extensive study (e.g., [5], [6], [7], [8]).…”
