Abstract
A network adapter includes a host interface configured to communicate with a host, a network interface configured to communicate with a communication network, and packet processing circuitry. The packet processing circuitry is configured to receive a packet from the host via the host interface, or from the communication network via the network interface, to receive an indication of a network time used for synchronizing network elements in the communication network, to match the packet to a rule, the rule including a condition and an action, and to perform the action in response to the packet meeting the condition, wherein one or more of (i) the condition in the rule and (ii) the action in the rule, depend on the network time.
