Network traffic flows can be processed by routers, switches, or service nodes. Service nodes may be ASICs that can provide the functionality of a switch or a router. Service nodes can be configured in a circular replication chain, thereby providing benefits such as high reliability. The service nodes can implement methods that include receiving a first packet that includes a source address in a source address field and that includes a destination address in a destination address field, routing the first packet to a selected service node that is in a circular replication chain that includes a plurality of service nodes that have local flow tables and are configured for chain replication of the local flow tables, producing a second packet by using a matching flow table entry of the first packet to process the first packet, and sending the second packet toward a destination indicated by the destination address.
