摘要： A number of wavelength division multiplexing (WDM) access nodes employ a distributed search based scheme to build network topology databases based on a set of connectivity constraints (1230). A set of one or more connectivity constraints that include quality or service (QoS) based criteria are applied on a physical network topology of a WDM optical network to divide that optical network into separate service levels (910) whose topologies (920) are determined for each of the service levels. A number of WDM access nodes of an optical network employ a source based scheme to establish communication paths (1145). Each of these access nodes stores a set of one or more network topology databases based on a set of connectivity constraints. Each of these nodes employs a messaging scheme to propagate notification of changes in the optical network to other nodes to maintain their databases.

摘要： A method and apparatus for implementing optical network quality using bit error rate and chromatic dispersion. According to one embodiment of the invention, a method includes the provision of quality of service in a wavelength division multiplexing optical network that supports a plurality of bit rates. As part of this method, the cumulative noise and cumulative chromatic dispersion for each available path as a whole is determined, where an available path is a series of two or more nodes each connected by an optical link on which a set of wavelengths is available for establishing a lightpath. In addition, different grades of path quality are distinguished based on bit error rate (BER), where BER is based on cumulative noise and bit rate. Furthermore, a minimum path quality is required based on chromatic dispersion decibel penalty, where chromatic dispersion decibel penalty is based on cumulative chromatic dispersion and bit rate.
