Abstract
A method is disclosed that enables the avoidance of a processor overload of a telecommunications endpoint device that is susceptible to traffic floods. An enhanced network switch sets the speed on one of its data ports as a specific function of the speeds of the devices that are connected to one or more of its other data ports. This behavior is different from that of network switches in the prior art, in which the data rate of a port in the prior art is auto-negotiated to the highest speed that can be supported by the network elements at either end of the port's connection, regardless of the other devices present. By considering the specific devices that are connected, the enhanced network switch is able to limit the amount of traffic that is directed by an upstream device, such as a router, towards a device with limited processor capability, such as a packet-based phone.
