The paper discussed the coordination control of the multi-layer network survivability scheme of IP/GMPLS over Optical based on the GMPLS. The scheme mainly studies the optimized settings of the fault detection, fault notification, waiting time; and described the detailed survivability coordination scheme of the integrated. And the scheme can reduce the sum of the time that we required to recover the...
In this paper, we study the shared path protection (SPP) problem in wavelength division multiplexing (WDM) optical networks, and propose a novel SPP algorithm with differentiated reliability (DiR) called SPP-DiR. Differing from previous work, SPP-DiR algorithm effectively adapts to the diversity demands of customer requests and has higher resource utilization than SPP algorithm. Therefore, SPP-DiR...
The size dependence of ionization potentials (IPs) of silicon clusters is studied using a localized orbital theory on the basis of the tight-binding approximation. The geometric structures of the silicon clusters are from the theoretical results of the force field model, and the hopping integral and overlap integral in the tight-binding Hamiltonian matrix are obtained from the best fitted formula...
