Mitigating threats in a network includes receiving a message at a network device. The message includes device-independent parameters generated in response to a threat. The network device converts the parameters into one or more device-specific operations and then performs the operations to mitigate the threat.

Mitigating threats in a network

Several keep-alive messages of point to point (PPP) sessions received from a remote system are aggregated into a single packet in an aggregation device (e.g., network access server). The aggregated packet is sent to a peer aggregation device (e.g., home gateway) at the other end of the PPP session. The peer aggregation device may send the status of the sessions in a single packet. As a result, the data traffic on a communication backbone due to keep-alive status checks may be reduced. Without waiting for the peer aggregation device to provide the status information, a proxy reply may be generated from the aggregation device.
