The SDN includes a controller to configure the plurality of network devices. The method includes receiving a sequence of packets of a data flow traversing the in-line service chain, applying a hash function to the sequence of packets of the data flow to generate a set of hash values for the sequence of packets, and sending the set of hash values and a set of timestamps for the sequence of packets to the controller to determine delay and loss across a service of the in-line service chain."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Passive performance measurement for inline service chaining","description":"A method is implemented by a network device to monitor the performance of packet processing in an in-line service chain, the network device one of a plurality of network devices forming a software def","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9705775","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
