The computer program logs into each network element in the line and sets a section trace transmit value for each circuit pack group (CPG). The computer program then logs into each network element in the line, and reads the value of a received section trace value of each circuit pack group...
(SynchronousOpticalNETwork/SynchronousDigitalHierarchy) A high-speed optical network technology used worldwide. SONET is employed in the U.S. and Canada, and SDH is everywhere else. SONET and SDH have relatively small differences; for example, the frame sizes are not identical, and some of the ...
Wavelength reuse for efficient transport of variable-size packets in a metro WDM network Metro WDM networks play an important role in the emerging Internet hierarchy; they interconnect the backbone WDM networks and the local access networks. Th... M Maier,M Scheutzow,MRA Wolisz - IEEE Infocom:...
