Abstract
As a server device receives packets from a client device, the server device counts the number of packets received over a particular time interval and compares the result with a preset packet transmission threshold. When the number of packets received from the client device in the time period reaches or exceeds the packet threshold, the server device can detect a potential malfunction of the client device and as such, refrains from processing further packets from the client device. By rate limiting based upon the number of packets received from the client device over a given time interval, rather than on the bandwidth taken by the requests received from the client device, the server device can minimize monopolization of the server device's resources as caused by the packets received at a relatively low rate from a client device.
