In an example, at least one SDN switch of an SDN marks a packet passing through the SDN switch with a packet tag, wherein the packet tag comprises an identifier of the SDN switch and a digest of a set of network forwarding rules of the SDN switch. Some examples generate, by a verifier, a verifier tag comprising the identifier of the at least one SDN switch and the digest of the set of network forwarding rules of the at least one SDN switch obtained from a network rules table and a network topology table stored in the verifier. Some examples receive, at a particular network element and from a verifier of the SDN, a request for attestation of the packet. Some examples check, by a verification engine, the packet tag against the verifier tag."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Verifying packet tags in software defined networks","description":"Examples relate to packet tagging in Software Defined Networks (SDN).
