Server Vision: A New Perspective for Next Generation Optical Networks
Under the current and foreseeable limitations of optical technology, performance of the next generation optical network is mainly hampered at the network node by resource contention. Existing work addresses contention resolution mostly in the wavelength domain (as wavelength conversion, WC), the time domain (buffering by using fiber delay lines, FDLs, the space domain (as deflection routing), and the burst domain (as segmentation). In this paper, a new architecture of optical networks-the server view based on optical networks is proposed. From the point of this new architecture, the network can be modeled as a server system with three type servers—the access server, the node server and the link server. The network performances such as cost, energy consume and network capacity can be affected by the capability of these three type servers. Unlike existing research activities that are focused on the node server design, we present the Dual fiber link (the link server solution) and IP calking (the access server solution) to ease the resource contention. To evaluate the performance of the proposed methods, computer simulations are conducted. The simulation results show these solutions can reduce the contention effectively with existing commercial devices.
