EA-HD: a novel link state update mechanism for ASON

EA-HD: a novel link state update mechanism for ASON When a connection request comes in a mesh optical network, the routers automatically choose the suitable routing paths and wavelength to it according to the network topology and link-state information saved in its global link-state database. Because some of these wavelengths may be released or occupied at any time, the global state database is always out of date and need update by some update policy. A suitable link-state update policy is critical, since a high-frequency update policy imposes heavy burden on the network, while a low-frequency update would increase the inaccurate of the global link-state database. In this paper, we propose a link-state update policy, named the EA-HD policy, which considers two index of a link, one is the Hamming distance between the local link-state database and the global link-state database, and the other is the used ratio of its wavelengths. The proposed update policy gets a trade-off between the accurate of link-state information and its update cost. Simulation results prove that our scheme achieves a good performance in traffic blocking probability while maintaining moderate volume of update traffic. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Photonic Network Communications Springer Journals

Abstract

When a connection request comes in a mesh optical network, the routers automatically choose the suitable routing paths and wavelength to it according to the network topology and link-state information saved in its global link-state database. Because some of these wavelengths may be released or occupied at any time, the global state database is always out of date and need update by some update policy. A suitable link-state update policy is critical, since a high-frequency update policy imposes heavy burden on the network, while a low-frequency update would increase the inaccurate of the global link-state database. In this paper, we propose a link-state update policy, named the EA-HD policy, which considers two index of a link, one is the Hamming distance between the local link-state database and the global link-state database, and the other is the used ratio of its wavelengths. The proposed update policy gets a trade-off between the accurate of link-state information and its update cost. Simulation results prove that our scheme achieves a good performance in traffic blocking probability while maintaining moderate volume of update traffic.
