A method is presented in which a system reduces the risk of an advanced persistent threat ('APT') detected at one or more network devices by implementing one or more mitigation actions depending on the nature of the detected threat. Accordingly, in response to detecting the risk of an APT at one or more network devices, a centralized controller implements one or more mitigation actions to minimize the vulnerability of an enterprise network to unauthorized access to one or more network resources. A centralized controller may therefore instruct one or more network devices to take appropriate mitigation actions depending on the nature of an APT detected on one or more network devices.

Advanced persistent threat mitigation

One embodiment is a source router that monitors the performance of an Ethernet network. The source router generates an Ethernet connectivity check request frame that includes a transmission timestamp, and transmits the Ethernet connectivity check request frame to a destination router. The source router receives a reply from the destination router that is transmitted in response to receiving the Ethernet connectivity check request frame and determines a round trip time between the source router and the destination router based on a time of receipt of the reply and the transmission timestamp.

Ethernet performance monitoring

A method, system, and apparatus are provided for maintaining a common unique session identifier for a call over a network. In at least one embodiment, a unique session identifier is created by appending the IP address of an access server to a local session identifier.

Maintaining a common AAA session ID for a call over a network

A method, system, and apparatus are provided for maintaining a common session identifier for a call over a network. In at least one embodiment, the session identifier is provided as a non-required parameter in accordance with a tunnel protocol.
