Routing and wavelength assignment in all-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...

Routing and Wavelength Assignment in All-Optical Networks

Abstracf— This paper considers the problem of routing connections in a reeontigurable optical network using wavelength division multiplexing. Each connection between a pair of nodes in the network is assigned a path through the network and a wavelength on that path, such that connections whose paths share a common link in the network are assigned d]fferent wavelengths. We derive an upper bound ...

Routing and wavelength assignment issues in the presence of wavelength conversion for all-optical networks

algorithm algorithm (Numerical results will be discussed in Section N). mnveraion We argue in this paper thnt any RWA algorithm h this paper, we propose a new dynamic RWA algorithm, needs to take into aeconnt the underlying wavelength conversion called weighred least-congesnon routing and firsv'it for two IFBJons: 1) wavelength converter placement is usually wavelength assignrnenl (WLCR-FF), wh...
