Abstract
One or more processing operations are performed on a packet at a first packet processing element of a plurality of packet processing elements of a network device. A processing state corresponding to processing of the packet is indicated in a packet processing context associated with the packet. An external processing engine is triggered for performing an additional processing operation on the packet, and processing of the packet is suspended by the first packet processing element. Subsequent to completion of the additional processing operation by the external processing engine, processing of the packet is resumed, based on the packet processing context, by a second packet processing element when the second packet processing element is available for processing of the packet and the first packet processing element is not available for processing of the packet.
