Techniques for de-intermediate a network path between a source and a destination are described. In an example, a source sends a first data packet destined for a destination. A network node on a network path between the source and the destination performs a network operation on the data packet and generates a set of instructions to indicate the network operation and parameters for performing the network operation. The set of instructions is sent as a stream update to the source. When the source needs to send a second packet to the destination, the source applies these instructions to the second packet. Thereby, similar network operations are performed on the second data packet at the source, thereby avoiding the need to send the second data packet on the same network path comprising the network node. Correspondingly, the second data packet is transmitted on a different network path that bypasses the network node.
