    • 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.
    • 公开了IP设备中自动拒绝服务保护的方法和系统。 分组在IP设备的网络接口处被接收,分组被寻址到网络接口的网络地址。 寻址到IP设备的网络接口的分组被转发到IP设备中的处理器。 处理器确定这些数据包是否违反IP设备的基于速率的监管策略。 响应于确定分组违反基于速率的监管策略,与分组相关联的源标识信息被添加到IP设备中的访问控制列表。 防止访问控制列表中的数据包匹配标准被转发到IP设备中的处理器。
