A dynamic hybrid residential threat detection method is disclosed. The method includes receiving, by a packet selector on a customer premises equipment (CPE), communication sessions and selecting and sending, by the packet selector, a predefined number of packets of the communication sessions to a CPE detection engine based on packet selection rules. The method also includes inspecting, by the CPE detection engine, the predefined number of packets of each communication session based on CPE detection rules that establish what type of inspection is to be performed by the CPE detection engine based at least in part on CPE resource constraints. The method further includes sending, by the packet selector, the predefined number of packets of at least some of the communication sessions to a cloud detection engine and blocking particular communication traffic on the CPE based on the inspection and/or an instruction from the cloud detection engine.

Hybrid customer premises equipment and cloud-based implementation of dynamic residential threat detection

A dynamic cloud-based threat detection system is disclosed. The system comprises a network broker that receives communication sessions associated with communication device(s) via a network and selects and sends a predefined number of packets of each communication session to a detection based on packet selection rules. The communication device(s) comprises customer premises equipment (CPE) and/or a mobile communication device. The detection engine receives and inspects the predefined number of packets of each communication session and a governor that initiates blocking of particular communication traffic based on the inspection. The system also comprises a dynamic optimizer that monitors factor(s) and creates and sends updated packet rules to the network broker based on the monitoring. The network broker selects and sends a different predefined number of packets of each of a second plurality of communication sessions to the detection engine for inspection based on the updated packet selection rules.

Cloud-based implementation of dynamic threat detection

A method of dynamic residential threat detection is disclosed. The method includes a packet selection component on a customer premises equipment (CPE) sending a predefined number of packets of each of a plurality of communication sessions to a detection engine based on packet selection rules. The method also includes the detection engine on the CPE receiving and inspecting the predefined number of packets. The method further includes a dynamic optimizing component on the CPE monitoring one or more factors and creating and sending updated packet selection rules based on the monitored factor(s) to the packet selection component. The method additionally comprises the packet selection component sending a different predefined number of packets of each of a second plurality of communication sessions to the detection engine based on the updated packet selection rules. The method further includes the detection engine receiving and inspecting the different predefined number of packets.

Customer premises equipment implementation of dynamic residential threat detection

A method and apparatus for mesh based protection of an optical network is described. A method comprises protecting a first set of one or more optical sub-channels with automatic protection switching, utilizing a second and third set of one or more optical sub-channels to transmit traffic in accordance with a mesh process to transmit traffic, and transmitting traffic in the third set of optical sub-channels, which would have been transmitted in the second set of optical sub-channels, in accordance with routes determined by the mesh process in response to an alarm indicating a failure affecting the second set of optical sub-channels.
