A method and system for managing electric power consumption by elements of a distributed computing system comprises: determining one or more system metrics that relate to electric power usage as consumed by elements of a configured distributed environment; determining a system value in response to the one or more system metrics, the value determined according to one or more value criteria; and, while in-progress applications are being run in the computing environment, evaluating one or more potential changes in the distributed computing environment and determining an alternate system value based on the changes; and, re-configuring elements of the distributed computing environment dynamically while the computing environment is operating, in accordance with a determined alternate system value. The re-configuring elements step is in accordance with a potential change operative to alter electric power consumption.

Managing electric power consumption by configuring elements of a distributed computing system

The present invention is a method of doing business over a network that: receives a request for transmitting digital information after a start time and before an end time, determines the time required to transmit the digital information based on the number of packets in the information and the network speed, schedules a transmit time for the digital information, and accepts the digital information for transmission only if the time required to transmit is less than or equal to the difference between the transmit time and the end time. Pricing of the transmission can be determined by the priority of transmission, whether the information is transmitted the first time or rescheduled, and whether the user receives an acknowledgment.

Method of doing business over a network by transmission and retransmission of digital information on a network during time slots

The present invention is a computer system for delivering digital information over a network. A request receiving process receives a request for transmitting digital information after a start time and before an end time. The digital information has a number of packets. A transmit time process determines the time required to transmit the digital information based on the number of packets and a network speed. A scheduler schedules a transmit time for the digital information and an acceptance process accepts the digital information for transmission only if the time required to transmit is less than or equal to the difference between the transmit time and the end time.

A computer dispatcher connected to one or more respective network buffers has stored file lists that identify one or more of the files in the database that are to be transmitted over networks connected to the respective network buffer. A scheduler(s) schedule one or more portions of one or more of the files to be written to the respective network buffers by defining transmission criteria about each of the files in the file list. These transmission criteria include a quantity to transmit criteria, defining a quantity of one or more of the portions of the respective file to transmit, and one or more release times. The release times define the time at which the respective portion is to be written to the network buffer. The system includes a dispatching process that determines an available space on one or more of the network buffers and a current system time. The dispatching process determines if the system time is greater than or equal to one of the release times and further takes a minimum value of the available space and the quantity of the respective portion. The dispatching process then writes the minimum value of the respective portion to one or more of the network buffers. A feedback mechanism, e.g. a quantity completion measure, is used to estimate a completion time of the writing of the respective portion to the respective network buffer. The scheduler then reschedules one or more of the portions if one or more of the portions can not be scheduled to meet the respective transmission criteria.

System and method for dispatching and scheduling network transmissions with feedback

The invention is a broadband network monitoring system and method. The system has one or more RF carrier generators that generate one or more generator signals, called a reference signal, each of the generator signals having a generator signal frequency. One or more RF transient detectors sense a line signal on one or more broadband lines in the broadband network. Each line signal has one or more test signals applied by a remote RF carrier generator. Each test signal has a frequency equal to one of the reference signals. Each RF transient detector senses and compares the test signal and the reference signal in various ways to produce a transient indicator when the test signal and reference/generator signal are not the same. The transient indicator indicates that there may be a perturbation or some other problem in the respective broadband line. A controller is connected to each of the RF transient detectors and controls an RF switch and an analyzer. The RF switch has two or more inputs connected to each respective RF detector and one output connected to the analyzer. When the controller receives a transient indicator, it controls the switch to connect the broadband line producing the transient indicator to the analyzer and, in a preferred embodiment, starts the analyzer. In this way, all of the broadband lines can be monitored and analyzed for perturbations using a single analyzer.

This invention is a broadband matrix switch system and method of operation. The broadband matrix switch has N number of broadband inputs, each of the broadband inputs having one or more broadband signals. The matrix switch has M number of broadband outputs. There are N number of splitters. Each of the splitters has a splitter input connected to one of the broadband inputs. Each of the splitters has M number of splitter outputs that produce the splitter output signal. There are N times M number of node switches. Each node switch is uniquely connected to one of the splitter outputs. The node switches have a control input that allows the node switch to pass the respective splitter output signal upon receiving a close command at the control input and to terminate the respective splitter output signal with an input impedance upon receiving an open command at the control input. There are M number of combiners. Each combiner has a combiner output connected to one of the broadband outputs. Each combiner further having N number of combiner inputs. Each of the combiner inputs are connected to one and only one of the inputs through the respective splitter and node switch. The node switches terminate the combiner input with an output impedance upon receiving an open command. The matrix switch further has a controller that sends one or more open commands to selected node switches to connect one or more of the broadband inputs to one or more of the broadband outputs. The matrix switch has many uses in switching and monitoring and analyzing broadband networks, for example, cable TV networks.

One or more servers and/or control functions that are connected to a network. One or more service providers provide information having content to the servers. The server/control function executes a process which parses the information content sent from the service provider onto two or more channels and then broadcasts those channels over the network to a plurality of client computers. The server process examines the information packets sent from the service provider to determine zero or more of the categories that describe a content of the information packet and labels the information packets with the channel identifier associated with the respective categories prior to sending the information packets over the network. The server can also run processes and broadcast commands to the clients that associate/disassociate channel identifiers with categories.
