Abstract
A method may include receiving a packet at an ingress line interface in a forwarding plane of a network element, the packet including header information. The method may also include conducting a flow table lookup in the forwarding plane to identify an existing flow for the packet and determining, in the forwarding plane and based on the header information, whether a predicted flow can be identified for the packet if an existing flow can not be identified. The method may further include performing a service access control list (ACL) lookup in the forwarding plane if a predicted flow can not be identified; and forwarding the packet to one of a services plane or an egress line interface in the forwarding plane based on one of the existing flow, the predicted flow, or the service ACL lookup.
