Abstract: Embodiments herein describe a configurable packet processing architecture for a SmartNIC or other network device. The configurable architecture includes a plurality of PPEs which are communicatively coupled using a packet bus. A packet can be processed in each of the PPEs. For example, each packet may be first processed by PPE 1, then PPE 2, then PPE 3, and so forth. Moreover, the results of processing the packet at a PPE 1 may affect the operation performed on the packet when it reaches PPE 2 or PPE 3. Thus, the PPEs form a chain where the results determined by a first PPE when processing the packet can affect or change the operation a second PPE performs when processing the same packet.
