Abstract
A first packet of a packet flow is received at a classifying network device. The first packet is forwarded from the classifying network device to a firewall network device. An indication that the packet flow is to be offloaded is received at the classifying network device. Data is stored at the classifying network device indicating that the packet flow is to be offloaded. A non-control packet of the packet flow is received at the classifying network device. A determination is made that the non-control packet belongs to the packet flow by comparing data contained in the non-control packet to the stored data. The non-control packet of the packet flow is directed to a processing entity in response to the determining. A control packet of the packet flow is received at the classifying network device. The control packet of the packet flow is directed to the firewall network device.
