Abstract

A system and method for throttling transmissions of gathered computer system monitoring and asset data within a customer'"'"'s communications network. A relay is provided within the network with an interface for transmitting messages to a downstream device such as the Internet. A data transmission throttle controls the downstream interface to transmit data at or below a data transfer threshold defining an allowable data transfer volume per transmission period. The method includes receiving customer input and modifying the data transfer threshold based on the input, with thresholds being set for a matrix of transmission periods (such as 24 hour by 7 day). The data transmission throttle determines whether messages exceed thresholds for the current transmission period, such as by comparing the size of the message to a data flow counter, and controls data transmissions by the relay to not exceed the threshold and by resetting the counter for each threshold.

Claims

1. A method for throttling transmission of gathered system monitoring and asset data within a communications network in a customer computing environment, comprising:

providing a communications relay within the communications network, wherein the communications relay includes a downstream interface for transmitting data messages to a downstream device and a data transmission throttle for controlling the downstream interface to transmit data at less than about a data transfer threshold defining an allowable data volume per transmission period;

receiving the gathered system monitoring and asset data at the communications relay for forwarding to the downstream device;

preparing a data message from the received data for transmittal by the downstream interface;

with the data transmission throttle, determining whether transmittal of the data message would exceed a data transfer threshold for a current transmission period; and

based on the determining, transmitting the data message with the downstream interface when the data transfer threshold is not exceeded or waiting a delay period and then transmitting the data message with the downstream interface.

2. The method of claim 1, wherein the delay period is calculated by the data transmission throttle to coincide the transmission with about a start of a next transmission period.

3. The method of claim 2, wherein a data transfer threshold of the next transmission period differs from the data transfer threshold of the current transmission period.

4. The method of claim 2, further including modifying the data transfer thresholds based on input from a user of the customer computing environment.

5. The method of claim 1, further including providing a network utilization matrix comprising for each day of the week a plurality of cells with a data transfer threshold.

6. The method of claim 5, wherein each of the cells corresponds to an hour of each day of the week and wherein the data transfer threshold for each of the cells is independently defined.

7. The method of claim 1, wherein the data message includes a priority assigned from a priority range and wherein the determining includes first determining if the assigned priority is a high priority and when the assigned priority is a high priority message, skipping to the transmitting of the data message with the downstream interface.

8. The method of claim 1, wherein the data transmission throttle includes a transmission counter initially set based on the data transfer threshold of the current transmission period and further including after the waiting a delay period and then transmitting the data message, resetting the transmission counter based on a data transfer threshold of a current transmission period and adjusting the transmission counter to reflect a size of the transmitted data message.

9. The method of claim 8, wherein the transmission counter is a decremental counter and further including after the transmitting the data message decrementing the transmission counter by a size of the transmitted data message.

10. A data communication relay, comprising:

a relay interface for transmitting digital data messages;

a memory device storing a plurality of throttling set points defining a plurality of data transfer rates providing a volume of data per transmission period;

a data flow counter configured for being set to one of the throttling set points and being decremented to indicate data transferred from the relay interface; and

a throttle mechanism adapted to control the relay interface by determining a current transmission period, retrieving a throttling set point for the current transmission period, setting the data flow counter to the throttling set point, and determining prior to the relay interface transmitting a digital data message whether the size of the digital data message is greater than the data flow counter.

11. The relay of claim 10, wherein the throttle mechanism is further adapted to decrement the data flow counter after the relay interface transmits the digital data message by the size of the message.

12. The relay of claim 11, wherein the throttle mechanism is further adapted when the size of the digital data message is greater than the data flow counter, to perform a system time call to determine whether a time returned from the system time call is within the current transmission period and if determined within the current transmission period, delaying transmitting of the digital data message until a next transmission period.

13. The relay of claim 12, wherein the throttle mechanism is further configured to operate if the returned time is in the next transmission period to retrieve a throttling set point for the next transmission period, to reset the data flow counter to the retrieved throttling set point, to compare the size of the digital data message to the data flow counter, and when the size is smaller than the data flow counter, to enable transmission of the digital data message and to decrement the data flow counter by the size of the digital data message.

14. A customer-based service system for providing self-service tools from a central service provider node linked to a data communications network to customer environments via the communications network, comprising:

a communication pipeline within a customer environment adapted for digital data transfer;

a plurality of monitored relays linked to the pipeline comprising end nodes running at least a portion of the provided self-service tools;

a forwarding relay linked to the pipeline upstream of the monitored relays adapted to control flow of data transmitted from the monitored relays to the service provider node, wherein the forwarding relay includes means for storing the transmitted data and selectively forwarding the stored data on the pipeline; and

a customer relay linked to the pipeline and to the communications network providing a communication interface between the forwarding relay and the service provider node, wherein the customer relay includes a data transmission throttle operating to maintain volumes of the forwarded data to the communications network per transmission period below about a network utilization threshold.

15. The system of claim 14, wherein the storing and forwarding means of the forwarding relay comprises priority queues for storing the transmitted data in files based on priorities and wherein the forwarded data from the priority queues designated as high priority are not included in the forwarded data volumes by the data transmission throttle.

16. The system of claim 14, wherein the data transmission throttle includes memory storing a plurality of values for the network utilization threshold corresponding to a plurality of the transmission periods, the transmission periods corresponding to a period of time for each day of a week and the values differing for at least some of the transmission periods.

17. The system of claim 14, wherein the data transmission throttle includes a data flow counter adapted to be set at the network utilization threshold and decremented for a size of each message of the forwarded data transmitted from the customer relay to the communications network, and wherein the data transmission throttle blocks at least a portion of the forwarded data from being transferred from the customer relay when the data flow counter is decremented to zero during a transmission period.

18. The system of claim 17, wherein the data transmission throttle is further functions to determine a current transmission period based on a system time call and to block the portion of the forwarded data for a delay period until a next transmission period or to reset the data flow counter to a network utilization threshold of the current transmission period and release the blocking of the portion.
