Examples of LightPaths:", "Image ImageDescription": "Analog wavelength on a CWDM or DWDM system.   STS channel on a SONET or SDH circuit.   ATM CBR circuit.   Diff serv gold service on a packet based network.   Gigabit Ethernet over dedicated fiber strand.   Definition by Bill St. Arnoud of Canarie. In a recent workshop at Canarie, Bill St. Arnaud introduced a term called a Lightpath . The definition most people seem to be happy with is Any uni-directional point to point connection with effective guaranteed bandwidth. Bill argued that a Lightpath could be implemented using various network technologies such as CWDM, DWDM, STS channels on a SONET/SDH circuit, ATM CBR circuit, A dedicated Diffserv Gold channel or GBE channels. Within our group at UvA, research is done into the formal representation of fiberconnections and its associated equipment. A mathematical representation using directed graphs with edges and vertrices are currently investigated as one way to present a network of switches and links. Some fundamental concepts are important to recognize: We identified 2 different classes of models: the Union and the Daisy Chain model.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
