We provide a comprehensive survey of packet-switched ring metro WDM networks. We first
review current standardization and testbed activities, then we provide a categorization of …

Wavelength division multiplexing (WDM)-based Passive Optical Networks (PON) has gained
attention due to the massive growth in bandwidth demand resulting from the increased …

Building on the Ethernet Passive Optical Network (EPON) and Gigabit PON (GPON)
standards, Next-Generation (NG) PONs (i) provide increased data rates, split ratios …

Both wavelength-division-multiplexing (WDM) networks with a ring architecture and WDM
networks with a star architecture have been extensively studied as solutions to the ever …

The paper proposes an original wavelength-division multiplexing slotted-ring network
architecture with nodes that use one fixed transmitter and fixed receivers. It is shown …

We consider a wavelength division multiplexing metro ring architecture with optical burst
switching. The ring consists of N nodes, and each node owns a home wavelength on which …

This article reviews various WDM ring architectures and pays special attention to their
implementation in the metropolitan environment. A number of possible network architectures …

Single-hop wavelength division multiplexing (WDM) optical ring networks operating in
packet mode are one of the most promising architectures for the design of innovative …

This article proposes a WDM slotted-ring network architecture. Used as a metropolitan
access network, it is shown through theoretical predictions and simulation results how a …

In this paper, we present a wavelength division multiplexing multiring metropolitan area
network architecture using a separate ring as control channel and a finite number of access …
