Distribution network automation is aiming at improving the reliability of power supply, ameliorating the power quality and improving the operate management efficiency. However, all kinds of technology are developing continuously, but one key element to improve the level of distribution network automation is to choose the reasonable, reliable, economic communication method. This issue analyze some...
The traffic grooming problem in optical networks has been extensively studied. It tackles the problem of aggregating sub-wavelength traffic onto optical lightpaths so that the network cost can be reduced. As of yet, the network cost considered is in terms of the number of wavelengths, SONET ADMs, and the amount of OEO processing. However, in recent years, the steadily rising cost of energy consumption...
We describe the architecture of PHAROS (Petabit Highly-Agile Robust Optical System), developed under the DARPA CORONET program. PHAROS provides traffic engineering, resource management and signaling solutions for highly-agile, large-capacity core optical networks. PHAROS technology facilitates rapid configuration of network resources to address dynamic traffic needs in future global military and commercial...
