Methods and apparatus for dynamic offline end-to-end packet processing based on traffic class. An end-to-end connection is set up between an application on a client including a processor and host memory and an application on a remote server. An offline packet buffer is allocated in host memory. While the processor and/or a core on with the client application is executed is in a sleep state, the client is operated in an interrupt-less and polling-less mode as applied to a predetermined traffic class. Under the mode, a Network Interface Controller (NIC) at the client receives network traffic from the remote server and determines whether the network traffic is associated with the predetermined traffic class. When it is, the NIC writes packet data extracted from the network traffic to an offline packet buffer. Descriptors are generated and provided to the NIC to inform the NIC of the location and size of the offline packet buffer.
