Abstract

See full text

For a logical switching element implemented across several managed switching elements, some embodiments provide a method that receives a packet for processing through a logical processing pipeline of the logical switching element. The method processes the packet through a first set of stages of the logical processing pipeline of the logical switching element. The method generates a set of context tag values for indicating that the packet has been processed through the first set of stages of the logical processing pipeline. The method forwards the packet to a managed switching elements of the several managed switching elements for the managed switching element to further process the packet based on the context tag of the packet.
