An edge router in each service zone or destination network advertises routes by its destination network prefix tagged with its route target. A service chain is created by importing and exporting of destination network prefixes by way of route targets at edge routers of the service zones or source networks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chaining service zones by way of route re-origination","description":"Presented herein are techniques for use in a network environment that includes one or more service zones, each service zone including at least one instance of an in-line application service to be appl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9826025","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.
