RFC 6163 Wavelength Switched Optical Networks
This document provides a framework for applying Generalized Multi-Protocol Label Switching (GMPLS) and the Path Computation Element (PCE) architecture to the control of Wavelength Switched Optical Networks (WSONs). In particular, it examines Routing and Wavelength Assignment (RWA) of optical paths. This document focuses on topological elements and path selection constraints that are common acro...
متن کاملWavelength Reusability in Wavelength-Routed Optical Networks
Recently routing and wavelength assignment (RWA) problem in wavelength-routed optical networks (WRON's) has been studied extensively. Different optimum criterions are proposed to evaluate the performance of designed networks, such as carried traffic [1], wavelength requirement [2,3], fiber requirement [4], and OXC system scale [5]. Because wavelength is a very limited network resource, most of ...
متن کاملReconfigurable wavelength-switched optical networks for the Internet core
With the quantity of data traffic carried on the Internet doubling each year, there is no let up in the demand for ever increasing network capacity. Optical fibres have a theoretical capacity of many tens of terabits per second. Currently six terabits per second has been achieved using Dense Wavelength Division Multiplexing: multiple signals at different wavelengths carried on the same fibre. T...
متن کاملRouting and Wavelength Assignment Information Encoding for Wavelength Switched Optical Networks
A Wavelength Switched Optical Network (WSON) requires certain key information fields be made available to facilitate path computation and the establishment of Label Switched Paths (LSPs). The information model described in "Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks" (RFC 7446) shows what information is required at specific points in the WSON. P...
متن کاملRouting and Wavelength Assignment Information Model for Wavelength Switched Optical Networks
This document provides a model of information needed by the Routing and Wavelength Assignment (RWA) process in Wavelength Switched Optical Networks (WSONs). The purpose of the information described in this model is to facilitate constrained optical path computation in WSONs. This model takes into account compatibility constraints between WSON signal attributes and network elements but does not ...
