SERVICE CHAINING HARDWARE ACCELERATORS WITHIN A DATA STREAM PROCESSING INTEGRATED CIRCUIT

摘要

This disclosure describes techniques that include establishing a service chain of operations that are performed on a network packet as a sequence of operations. In one example, this disclosure describes a method that includes storing, by a data processing unit integrated circuit, a plurality of work unit frames in a work unit stack representing a plurality of service chain operations, including a first service chain operation, a second service chain operation, and a third service chain operation; executing, by the data processing unit integrated circuit, the first service chain operation, wherein executing the first service chain operation generates operation data; determining, by the data processing unit integrated circuit and based on the operation data, whether to perform the second service chain operation; and executing, by the data processing unit integrated circuit, the third service chain operation after skipping the second service chain operation.
