چکیده

We consider protection and restoration mechanisms for hierarchical optical networks with different granularities of paths (wavelengths and wavebands). We formulate an Integer Linear Programming description for the problem and propose a shared-path waveband protection algorithm. We further demonstrate its efficiency by analyzing its equipment cost and capacity utilization.

Effects of Optical Layer Protection Granularity in Survivable Hierarchical Optical Path Network

This study compares the performances of waveband protection and wavelength path protection in survivable hierarchical optical path networks. Network costs and the number of switching operations necessary are evaluated for different ratios of protected demand. Numerical results demonstrate that waveband protection can drastically decrease the number of switching operations in the case of failure...

Optical Fast Circuit Switching Networks Employing Dynamic Waveband Tunnel

We propose a novel dynamic hierarchical optical path network architecture that achieves efficient optical fast circuit switching. In order to complete wavelength path setup/teardown efficiently, the proposed network adaptively manages waveband paths and bundles of optical paths, which provide virtual mesh connectivity between node pairs for wavelength paths. Numerical experiments show that oper...

An Algorithm for Waveband Routing and Wavelength Assignment in Hierarchical WDM Mesh Networks

Aggregation of wavelengths into wavebands is an attractive, cost-efficient way to facilitate switching and routing in optical networks. In this paper, we study the waveband routing and wavelength assignment (WRWA) tasks in hierarchical WDM mesh networks with optical crossconnects that can route multiple granularity (wavelengths and wavebands) at the same time. We solve the waveband routing and ...

Optical Cross-Connect Switch Architectures for Hierarchical Optical Path Networks

This paper proposes new switch architectures for hierarchical optical path cross-connect (HOXC) systems. The architectures allow incremental expansion of system scale in terms of the number of input/output fiber ports, wavebands, and optical paths per waveband. These features assure the cost-effective introduction of HOXCs even at the outset when traffic volume is not so large. Furthermore the ...
