The Standby Servers use the same Internet Protocol (IP)-address(es) on the SCTP bound interfaces as their assigned Active Server. The Active Servers are effectively communicating to the SCTP-clients, where the Standby Servers are communicating to their assigned Active SCTP-Server using a separate backchannel TCP-connection. Over that backchannel connection the Standby Server receives regular updates from the Active Server. These updates hold enough information so that the Standby Server could locally simulate SCTP-negotiations and create SCTP-associations as if the SCTP-negotiations were performed directly with the SCTP-Clients. In this manner the Standby Servers are fully synchronized and ready in case of an Active Server failure to continue the SCTP-communications without any interruption. This handover does not involve any subsequent action from the SCTP-clients so that the SCTP-clients are unaware that such a handover took place."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for seamless SCTP failover between SCTP servers running on different machines","description":"A Stream Control Transmission Protocol (SCTP) cluster of multiple SCTP-servers is defined in such manner that some of the servers are assigned Active Role where others are assigned Standby Role with t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641415","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.
