“…Digital signals from a CMTS are distributed through optical fibers organized in a tree hierarchy to optical nodes, where they are converted into electrical formats and sent to the CMs at subscribers' home using coax cables [8,11]. Both the downstream (DS) and upstream (US) channels in HFC networks are shared by the subscribers in a time-division multiplexing (TDM) manner.…”

“…Hence, the network is dimensioned for peak traffic load. Nevertheless, due to the daily life pattern of end users, the traffic in a HFC network can have relatively large hourly fluctuations [11]. This fact suggests that some of the CMs' transceivers and even CMTS ports can be greatly under-utilized during low-traffic hours.…”

EVWUDFW-We propose a traffic-aware and cooperative approach to achieve energy-saving in Hybrid Fiber-Coaxial (HFC) networks that support DOCSIS 3.0 standard. The approach incorporates a two-step operation that consists of two algorithms, one for the Cable Modem (CM) side and the other for the Cable Modem Termination System (CMTS) side. To avoid transition overheads, we design both algorithms with the consideration of energy-to-NoC (Number of Changes) tradeoff and try to minimize the number of Dynamic Bonding Change (DBC) operations while saving the energy. Simulations verify the effectiveness of the algorithms by using a realistic HFC network traffic model, and the results demonstrate significant saving on the ON-time (energy consumption) of the CMs' channels and the CMTS' ports. ,QGH[ 7HUPV-Hybrid Fiber-Coaxial (HFC) Networks, DOC-SIS 3.0, Traffic-aware design, Energy-efficient networks

“…In the context of this work, we assume that the upstream (US) capacities (i.e., the traffic capacity from CMs to a CMTS LC) of the master and slave LCs are identical, but the master LC's downstream (DS) capacity (i.e., the traffic capacity from a LC to CMs) is larger than that of the slave one. This assumption is valid since the traffic of HFC networks is asymmetric [12] and the DS provision speed of a CM is normally larger. Hence, we can trigger LC switching based on DS traffic only.…”

We develop a novel traffic scheduling algorithm based on a master-slave linecard (LC) configuration to improve the energy-efficiency of hybrid fiber-coaxial (HFC) networks. The algorithm forwards packets to the master or slave LC adaptively according to the traffic load, and toggles the LCs between working and sleeping modes for energy-saving. To optimize the algorithm's key parameters, we model the system using a twodimensional Markov process and derive the analytical expressions of several performance metrics, including average packet delay, LC switching frequency, and energy efficiency improvement. We then verify the theoretical analysis with numerical simulations using the Monte Carlo method. Both the theoretical and simulation results indicate that the proposed algorithm can achieve significant energy efficiency improvement, while keeping the average packet delay and LC switching frequency low.

“…To date, there are several candidates for an integrated access networks platform, including Full Service Access Network (FSAN) [4,5] , Hybrid Fiber Coax (HFC) networks [6] and PON [7][8][9][10][11][12] . Among them, PON is one of the most promising solutions for the fiber-to-the-office (FTTO), fiber-to-the-home (FTTH), fiber-to-the-business (FTTB), and fiber-to-the-curb (FTTC) applications.…”

In this paper, a novel Passive Optical Network based on Optical Code Division Multiple Access (OCDMA-PON) is presented. The design of the Optical Line Terminator (OLT) and the Optical NetworkUnit (ONU) for the OCDMA-PON are studied in detail. The proposed OCDMA-PON combines the advantages of PON and OCDMA technology and it can be applied to an optical access network with full services on demand, such as internet protocol, video on demand, tele-presence and high quality audio. Compared to other multiple access technologies, the proposed OCDMA-PON provides more ONU and assembly flexibly for PON. We analyze in detail the scalability and system transmission performance of such a network. Simulation results indicate that the proposed scheme is feasible and that the novel design can improve the scalability and transmission performance of the optical access networks.passive optical network, optical code division multiple access, optical orthogonal code, optical line terminator, optical network units, architecture of the networks
