Abstract: A system and method for optimizing the use of network resources is described. In one embodiment, an enterprise first requests provisioning of network resources for a particular transaction. Responsive to that request, network resources are dynamically configured to meet the enterprise's request. When the transaction is complete, the network resources are returned to a default state.

Abstract: A method and apparatus to configure, monitor and manage network devices without regard for device type and/or manufacturer is disclosed. One implementation of this embodiment includes a network manager unit disposed between the network administrator and the network devices. The network manager unit allows the administrator to holistically view, configure and manage an entire network without regard to device type and/or manufacturer. The administrator can implement this holistic approach with the use of a central repository for all configuration information and/or a central posting location for all network events.

Abstract: A method of refurbishing a transition duct (100) for a gas turbine system includes providing the transition duct. The transition duct has a first wall (221) defining a first passageway (110) and having holes (223) through a metal layer (322) and a ceramic layer (323), and the transition duct also has a second wall (222) adjacent to and separate from the first wall and external to the first passageway, where the first and second walls define a second passageway (210) coupled to the first passageway through the holes in the first wall. The method further includes masking the holes in the first wall, sealing the first passageway, and after sealing the first passageway, using a liquid etchant to chemically remove the ceramic layer from the first wall while keeping the liquid etchant out of the second passageways.
