At a first Traversal Using Relay NAT (TURN) server designated as a relay candidate by a TURN Virtual Internet Platform (VIP), it is determined that a first port allocated by the symmetric NAT for a first request for communication initiated by the first peer and directed to the TURN VIP, is different from a second port allocated by the symmetric NAT for a first packet transmitted from the first peer to the first TURN server, based on a first indication. The second port is mapped to the first port. Using a similar port mapping for the second peer, peer-to-peer communication between the first and second peers is enabled."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Peer-to-peer communication for symmetric NAT","description":"Systems and methods for communicating between a first and a second peer using interactive connectivity establishment (ICE) protocol, the first and second peers sharing a symmetric network address tran","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9826044","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.
