The AWG||PSC Network: A Performance Enhanced Single-Hop WDM Network with Heterogeneous Protection
Single–hop WDM networks based on a central Passive Star Coupler (PSC) or Arrayed–Waveguide Grating (AWG) hub have received a great deal of attention as promising solutions for the quickly increasing traffic in metropolitan and local area networks. These single–hop networks suffer from a single point of failure: If the central hub fails, then all network connectivity is lost. To address this sin...

متن کاملAWG Network: A Practical Single–Hop Metro WDM Network for Efficient Uni– and Multicasting
Single–hop WDM networks with a central Passive Star Coupler (PSC), as well as single–hop networks with a central Arrayed–Waveguide Grating (AWG) and a single transceiver at each node, have been extensively studied as solutions for the quickly increasing amounts of unicast and multicast traffic in the metropolitan area. The main bottlenecks of these networks are the lack of spatial wavelength re...
متن کاملArchitecture and access protocol for a wavelength selective single hop packet switched metropolitan area network
Current SONET/SDH metro ring networks create the so–called metro gap which prevents high– speed clients from tapping into the vast amounts of bandwidth available in the backbone. To bridge this gap we propose and investigate by means of analysis and simulation a novel arrayed– waveguide grating (AWG) based single–hop wavelength division multiplexing (WDM) network with a physical star topology. ...
متن کاملWavelength Reuse for Efficient Packet-Switched Transport in an AWG Based Metro WDM Network
Metro WDM networks play an important role in the emerging Internet hierarchy; they interconnect the backbone WDM networks and the local access networks. The current circuit-switched SONET/SDH-over-WDM-ring metro networks are expected to become a serious bottleneck — the so-called metro gap — as they are faced with an increasing amount of bursty packet data traffic and quickly increasing bandwid...
