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 data between a sender and a receiver, wherein a first schedule is generated at the sender for sending data to the receiver, said method comprising:

generating a second schedule at the receiver for receiving data from the sender, the second schedule being generated by varying the first schedule so as to intentionally cause a predetermined probability of failure in the receiving of said data; and

upon detecting a failure, generating an event at the receiver.

2. The method of claim 1, wherein data from the sender not being received at the receiver a predetermined number of times constitutes a failure.

3. The method of claim 1, wherein said step of generating a second schedule includes establishing at least one expectation window for receiving data from the sender.

4. A computer-readable medium having computer-executable instructions for performing the steps recited in claim 1.

5. One or more computer-readable media having computer-executable instructions for performing a method for exchanging data between a sender and a receiver, wherein a first schedule is generated at the sender for sending data to the receiver, said method comprising:

generating a second schedule at the receiver for receiving data from the sender, the second schedule being generated by varying the first schedule so as to intentionally cause a predetermined probability of failure in the receiving of said data; and

upon detecting a failure, generating an event at the receiver.

6. The media of claim 5, wherein data from the sender not being received at the receiver a predetermined number of times constitutes a failure.

7. The media of claim 5, wherein said step of generating a second schedule includes establishing at least one expectation window for receiving data from the sender.
