Abstract:
Methods and systems are provided for steering network packets. According to one embodiment, a dynamically configurable steering table is stored within a memory of each network interface of a networking routing/switching device. The steering table represents a mapping that logically assigns each of the network interfaces to one of multiple packet processing resources of the network routing/switching device. The steering table has contained therein information indicative of a unique identifier/address of the assigned packet processing resource. Responsive to receiving a packet on a network interface, the network interface performs Layer 1 or Layer 2 steering of the received packet to the assigned packet processing resource by retrieving the information indicative of the unique identifier/address of the assigned packet processing resource from the steering table based on a channel identifier associated with the received packet and the received packet is processed by the assigned packet processing resource.
