Abstract

A denial of service (DoS) detection and circumvention system is described herein. The DoS detection and circumvention system can track phone calls that are initiated and store a list of phone numbers that are called. The DoS detection and circumvention system can also track the number of carrier congestion messages over a certain time window. Using the list of called phone numbers and the tracked number of carrier congestion messages, the DoS detection and circumvention system can identify excessive congestion. If the DoS detection and circumvention system identifies excessive congestion, the DoS detection and circumvention system can delay calls so as to prevent a possible DoS condition.
