A Novel Quasi-Passive, Software-Defined, and Energy Efficient Optical Access Network for Adaptive Intra-PON Flow Transmission

Abstract: In this paper, we propose, design, and demonstrate a novel Intra-PON Flow transmission with optical reroute using a Quasi-PAssive Reconfigurable (QPAR) node The network can be reconfigured adaptively according to the monitored traffic status in a software-defined manner Simulations show that PON with reroute architecture can achieve ∼20% higher network capacity comparing to PON without reroute case with the same traffic waiting time or blocking probability requirement PON with reroute consistently outperforms PON without reroute configuration with 20% larger throughput and 24% less power consumption with the Intra-PON traffic ratio of 03 In addition, adaptive Intra-wavelength assignment with a QPAR node can adapt to the subscription rate growth with time, and provide cost and power savings compared to PON without reroute and fixed PON with reroute architectures by approximately 20% and 10% Moreover, adaptive Intra-PON architecture with a QPAR node can facilitate efficient multicast transmission for video or file backup among multiple serves located in different access networks, which can provide lower traffic waiting time, 14% power saving, and support roughly 30% higher traffic comparing to the fixed PON with reroute design with a multicast ratio of 05

A protocol to implement Ethernet over PON

Abstract: In this paper we propose a solution to implement Ethernet over PON using two unidirectional channels for access networks. The protocol called TUR is efficient and scalable and easy to implement using conventional mature technologies. We discuss strategies to deploy both upstream as well as downstream communication. Possible end-user designs are also discussed in connection to the protocol. A simulation study verifies the protocol and compares to contemporary solutions.

Abstract: A dynamically reconfigurable TDM-DWDM PON for converged multi-services at the physical layer (10G, 100G and wireless fronthaul) has been demonstrated for the first time implementing end-to-end SDN management of the access and core network elements.

Energy Evaluation for Cloud RAN Employing TDM-PON as Front-Haul Based on a New Network Traffic Modeling

Abstract: Cloud radio access network (C-RAN) is a novel network architecture to meet the ever-increasing user demands. Specially, the operating expense of C-RAN, including the energy consumption, is an issue of common concern. Former studies in energy consumption evaluation of C-RAN only considered the case of one virtual server and one remote radio head, which ignored the optical front-haul and cannot provide an overall analysis for the whole access network. In this paper, we analyze the energy consumption of the whole C-RAN architecture, employing Ethernet-based time division multiplexing passive optical network (TDM-PON) (i.e. 10G EPON) as the optical front-haul. Obviously, it becomes complex to analyze the energy problem for the whole network after bringing in the front-haul part. Based on queueing theory, this paper provides a new network traffic modeling for energy analysis in C-RAN. And, we propose a strategy to make the system work in the most energy-efficient state considering the quality of service. In addition, the comparison between C-RAN and 10G-EPON-LTE architecture has also been conducted. We analyze the power-delay tradeoff, the power changes along with request arrival rate, and the daily power distribution in the two networks. From the numerical results, C-RAN architecture can save more than 60% power in a typically low request arrival rate, and reduce about 40% energy for a whole day, considering the daily user behavior, which demonstrates its large potential in the next generation network.

An efficient multi-OLT and multi wavelengths passive optical network for differentiated classes of services

Abstract: Passive optical network (PON) is getting more popularity because it provides large bandwidth, uses only passive components that requires less power consumption, highly dynamic access network, and effectively converges several service providers. With the increase of multiple users having different priority classes of services an efficient access network is required which can handle the different data classes with better quality of services (QoSs). Usually, a single optical line terminal (OLT) and single wavelength (SS) PON is capable to provide multiple services and applications such as IPTV, HDTV, video conferencing, and real-time data transmission. However, the SS-PON is not the best network architecture to maintain better QoSs for all those services because it requires a complex dynamic bandwidth allocation (DBA) algorithm and synchronization of local time those lead a large delay. To overcome those problems in SS-PON, in this paper, we propose an efficient PON architecture which consists of two OLTs and two uplink wavelengths, i.e., multi-OLT and multi-wavelengths PON (MM-PON), for different classes of services. Here, two OLTs are used to reduce the data processing complexity and two uplink wavelengths are used to transmit the three different priority classes of services defined by IEEE802.1D standard. This paper presents a new network structure of MM-PON with simulation results for modified limited service DBA algorithm to prove the validity of the proposed network architecture. The simulation results show that the MM-PON with strict priority scheduling provide less packet delay, reduce the probability of packet loss, remove light load penalty, and maintain service level agreements for each priority class of service than the conventional SS-PON.
