Abstract
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.
