    Abstract: A method and systems for dynamically distributing packet flows over multiple network processing means and recombining packet flows after processing while keeping packet order even for traffic wherein an individual flow exceeds the performance capabilities of a single network processing means is disclosed. After incoming packets have been analyzed to identify the flow the packets are parts of, the sequenced load balancer of the invention dynamically distributes packets to the connected independent network processors. A balance history is created per flow and updated each time a packet of the flow is received and/or transmitted. Each balance history memorizes, in time order, the identifier of network processor having handled packets of the flow and the associated number of processed packets. Processed packets are then transmitted back to a high-speed link or memorized to be transmitted back to the high-speed link later, depending upon the current status of the balance history.
