Abstract: A method and apparatus for collecting statistics data over a communications network using scalable stateless processes are disclosed. A process capable of obtaining statistics data, in one embodiment, detects a delay associated with the availability of statistics data in accordance with predefined lag duration, and subsequently, adds one or more stateless processes to a pool of stateless processes to increase capacity of collecting statistics data. Upon enabling a stateless process to collect statistics data from network element (“NE”) in response to a statistics collecting tasks, the statistics data is stored in a database.

Abstract: An apparatus and method for transferring information in bulk between network devices employing File Transfer Protocol (“FTP”) are disclosed. During a network discovery process, an Element Management System (“EMS”) initiates a file generation command formatted with Simple Network Management Protocol (“SNMP”) to one or more network element (“NE”). After obtaining configuration information from one or more network devices, an NE, in one embodiment, establishes a file containing the configuration information and subsequently stores the file in a storage location. The file formatted in SNMP format is forwarded to EMS suing FTP/SFTP (secure file transfer protocol)/TFTP (trivial file transport protocol).

Abstract: A hybrid power generation system for generating electrical power comprises a compressor for producing a compressed oxidant and a recuperator in flow communication with the compressor. The hybrid power generation system further comprises a fuel cell assembly comprising a plurality of fuel cells in flow communication with the recuperator to provide the compressed oxidant for the fuel cell assembly. The hybrid power generation system further comprises a tail gas burner in flow communication with the fuel cell assembly. A control system is used for controlling the amount of cathode exhaust stream introduced in the tail gas burner for stable combustion and reduction of fuel and carbon monoxide emission. The hot compressed gas from the tail gas burner is introduced to a turbine, where the hot compressed gas is expanded, thereby producing electrical power and an expanded gas.
