Distributed network firewall and flow-based forwarding system

摘要

A method performed by a network appliance having a plurality of application processing units, includes: receiving a first packet at the network appliance; calculating a first value using a mathematical algorithm based on one or more information regarding the first packet; and using the calculated first value to identify a first application processing unit of the plurality of application processing units in the network appliance. A network appliance includes: a plurality of processing units that are communicatively connected to each other; wherein a first processing unit of the plurality of processing units is configured for: calculating a first value using a mathematical algorithm based on one or more information regarding a first packet; and using the calculated first value to identify a second processing unit of the plurality of processing units.
