In one example, a network device includes a network interface that receives a packet, a storage card that stores session data for monitored network sessions, a plurality of service processing cards that process packets of respective subsets of the network sessions, wherein each of the service processing cards comprises a respective memory to store session data for the respective subset of the network sessions processed by the corresponding service processing card, and a switch fabric coupled to the network interface, the storage card, and the plurality of service processing cards. One or more of the plurality of service cards process the received packet based on the session data stored by the storage card. The one or more of the plurality of service cards retrieve the session data for the network session to which the packet corresponds from the storage card and store the retrieved session data in the respective memory.

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.
