Abstract

A system and method are provided for exchanging data at irregular intervals between a sender and a receiver. The sender transmits to the receiver reports containing subject data along with information regarding the next interval at which subject data will be transmitted to the receiver. The receiver may create an expectation window corresponding to the interval information. In a network environment, the level of non-management traffic is monitored, and an average interval value for exchanging management data is selected as a function of the level of non-management traffic. Then, interval values are randomly generated based on the selected average interval value, and the management data is transmitted from the sender to the receiver at irregular intervals corresponding to the interval values.

Claims

1. A method for exchanging management data between a sender and a receiver over a communications link, said method comprising:

monitoring the level of non-management traffic over the communications link;

selecting a desired average interval for exchanging management data between the sender and the receiver as a function of the level of non-management traffic over the communications link;

generating a plurality of irregular interval values as a function of the selected average interval value; and

transmitting management data from the sender to the receiver at irregular time intervals corresponding to the generated interval values.

2. The method of claim 1, wherein the communications link is a network.

3. The method of claim 2, wherein said monitoring step includes measuring the network bandwidth.

4. The method of claim 3, wherein said selecting step includes selecting the seed number so that the management traffic is inversely proportional to the non-management traffic.

5. The method of claim 1, wherein the sender is a personal computer and the receiver is a management machine.

6. The method of claim 5, wherein the personal computer includes a central processing unit (CPU) and said monitoring step includes measuring the utilization of the CPU.

7. The method of claim 5, wherein the personal computer includes a memory and said monitoring step including measuring the utilization of the memory.

8. One or more computer-readable media having computer-executable instructions for performing the method recited in claim 1.
