Methods and systems for measurement-based call admission control in a media gateway are disclosed. A request for establishing a new voice-over-IP (VoIP) call for sending and receiving voice over IP packets in a media gateway is received. The request indicates a required bandwidth for the new call. Bandwidth utilization of at least one Internet protocol (IP) network interface for sending and receiving voice over IP packets in the media gateway is determined. The media gateway determines whether to admit the new VoIP call based on the determined requested bandwidth for the new call and the determined bandwidth utilization for at least one of the IP network interfaces.

Methods and systems for automatic denial of service protection in an IP device are disclosed. Packets are received at a network interface of an IP device, the packets being addressed to a network address of the network interface. The packets addressed to the network interface of the IP device are forwarded to a processor in the IP device. The processor determines whether the packets violate a rate-based policing policy of the IP device. In response to determining that the packets violate the rate-based policing policy, source identifying information associated with the packets is added to an access control list in the IP device. Packets matching criteria in the access control list are prevented from being forwarded to the processor in the IP device.
