Protocol Design for Wavelength Routing in Optical Ring Access Networks

Burst optical deflection routing protocol for wavelength routing WDM networks

Given the significant progress made and the continuing advances expected in the optical networking technology, it becomes attractive to build a future Optical Internet that natively supports bursty IP datagrams. Burst switching WDM optical networks are touted as suitable network architectures for future Optical Internet backbones. However, the lack of optical processing capabilities results in ...

Design, performance and wavelength assignment of a wavelength division multiaccess protocol for optical fibre ring networks

This paper presents a multiaccess strategy for use over optical fibre ring networks employing two counter rotating rings, and using wavelength division multiplexing. Transmitters employ tunable lasers, while receivers employ one or more fixed wavelength filters. The paper introduces an algorithm for the optimal assignment of the receivers to the channels, such that the possibility of finding an...

Novel Devices for Wavelength Routing and Optical Access Networks

Growth in internet traffic, perceived by some to be as high as 200% per annum [1], encouraged the widespread deployment of dense wavelength division multiplexing (DWDM) during the boom in optical communications between 1998 and 2001. By simply adding new wavelengths in existing fibers, DWDM was seen as a cost effective means for increasing network capacity to meet the growing demand without req...

Routing and Wavelength Assignment in Optical Networks

A Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks

Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of  regeneration capabilities, the physical layer i...
