Patent ID: 11463939

Abstract:
A system and method for implementing Transport Layer Security (TLS) Routing Agent in an Internet Protocol Exchange (IPX) network for 5G core roaming. Transmission Control Protocol (TCP) connections are established between the TLS Routing Agent and consumer Security Edge Protection Proxy (cSEPP) and producer Security Edge Protection Proxy (pSEPP). TLS Routing Agent receives HTTP/2 CONNECT request from cSEPP. The TLS Routing Agent routes subsequent TLS handshake and HTTP/2 application messages to producer-SEPP transparently, so that the end-to-end TLS security is maintained. The TLS Routing Agent enables message firewall to protect mobile operator's SEPP. The TLS Routing Agent applies policy routing to route HTTP/2 message intelligently across the IPX network and improves TCP performance by dividing the long Round-Trip-Time between TCP end points into shorter segments.
