A network of network appliances is configured with a policy configuration. Each network appliance is configured to validate each wide area network packet against the policy configuration. The validation can include verifying that the packets meet the SD-WAN network segment requirements and security rules including verifying that the source and destination address of the packet meet the firewall zone requirements. Each wide area network packet contains a policy header that is checked by the sending and receiving network appliance against the policy configuration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method device and system for policy based packet processing","description":"Provided are methods, apparatus, and system for policy based wide area network.
