Efficient Distributed Control Protocols for WDM All-Optical Networks
نویسندگان
چکیده
Path Multiplexing (PM) and Link Multiplexing (LM) [3, 5] are two approaches for establishing connections (or lightpaths) in optical networks. This paper describes distributed control protocols for establishing lightpaths in WDM networks using LM and PM. We propose and evaluate the performance of two classes of protocols, namely Source Initiated Reservation (SIR) and Destination Initiated Reservation (DIR). It is found that DIR protocols generally perform better than SIR protocols. However, the impacts of DIR protocols on the performance of a network using LM and PM are different.

Distributed Control in Optical Wdm Networks
This paper describes and evaluates distributed wavelength reservation protocols for all{optical WDM networks. These protocols are essential for applying WDM techniques to large scale all{optical networks. The protocols ensure that the wavelengths on the links along a path are reserved before communication takes place. A message is transmitted using the reserved wavelengths and remains in the op...
متن کاملPolymorphic control for cost-effective design of optical networks
A WDM optical layer can provide differentiated services to various upper layer protocols by forming many virtual optical networks (VONs). Polymorphic control of an optical layer in the form of On-demand-reconfiguration in some VONs and Self-reconfiguration in other VONs is proposed. The former is suitable for bursty traffic and short-lived connections, and the latter is for steady traffic and l...
متن کاملA Review of MAC Protocols for All-Optical Networks
All-optical networks that employ wavelength division multiplexing (WDM) are an attractive architecture for future high-speed networks. Through WDM, multiple channels are created on a single fiber, and an aggregate network bandwidth far greater than the peak electronic processing speed can be realized. This paper provides a review and an extensive bibliography of proposed media access control (M...

متن کاملEfficient Distributed Control Routing and Wavelength Assignment Mechanism for a Scalable Hierarchical Single-hop WDM all-Optical Interconnection Network
In this paper we propose an efficient distributed routing and wavelength allocation method for a Single-hop WDM (Wavelength Division Multiplexing) all-Optical Interconnection Network for Scalable Multiprocessor systems. By wavelength allocation, we mean the assignment of unique wavelength(s) to the access nodes. The WDM techniques enable extraction of a larger amount of usable bandwidth. Routin...
