This paper proposes a routing, wavelength and mode assignment algorithm which can be well applied in space division multiplexing transmission network. The simulation results show that this algorithm improves the blocking probability.
Ant Colony Optimization (ACO) is a popular research field these years. Ants choose paths where pheromone concentration is higher and modify the environment they visited. However, in the context of multi-service in multi-level and multi-domain optical network, the capacity of inter-domain links is limited. Congestion may be occurred at inter-domain links. In this paper, ant colony optimization algorithm...
PCE is an emerging technology to aggregate path computation tasks in some certain elements. The location of these elements may influence network performance. In this paper, an ILP model for PCEs location problem is formulated and a heuristic algorithm is proposed. Simulations are conducted to evaluate the effectiveness of the algorithm presented.
This paper introduces a dynamic bandwidth assignment algorithm designed for ring topology (R-DBA) in order to meet the needs of the construction of Metropolitan Area Network (MAN).This algorithm targets ring topology, based on fair iteration, supports various Qos services and has previous assignment mechanism.
A novel global quality of transmission (QoT) optimization scheme is proposed for GMPLS-based reconfigurable transparent optical networks. By perceiving and controlling the transmission impairments and state of tunable compensators, dynamic QoT optimization is implemented on the fly. Simulation results show that, the proposed QoT optimization can avoid unnecessary compensator adjustment and lower operating...
We investigate the impact of channel plan (CP) for upgrading network capacity in multi-rate transparent networks. A novel dispersion optimized channel plan (DOCP) scheme is proposed. Simulation results show that the proposed scheme improves the network performance significantly.
This paper designs a PCE-based architecture of routing, and proposes two distributed signaling schemes in PCE-based wavelength switching optical network (WSON). Simulation results based on the topology of Chinese core network are given and analyzed.
