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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and systems for service state replication using original data packets","description":"Network traffic flows can be processed by routers, switches, or service nodes.
