Claim of US Patent No. 10,585,725

20. A network element that processes network data with a data processing pipeline, the network element comprises:a port that receives incoming network data;
a data plane that includes a data processing pipeline that processes the network data;
memory that stores a new image for the data processing pipeline; and
a control plane that prepares the new image for the data processing pipeline of the network element, puts the data processing pipeline into a non-forwarding mode, writes the new image into the memory, and puts the data processing pipeline into a forwarding mode, wherein the new image modifies one or more functionalities of the data processing pipeline and the data processing pipeline processes network data received by the network element using the new image.
