PSA 2.0

Technical Explanation

The PDU Session Anchor (PSA) is the final termination point of a cellular data session before traffic enters the public internet or enterprise data network. In 6G, PSA 2.0 supports multipath bonding, simultaneously receiving traffic from Sub-THz cellular beams, Wi-Fi 8, and LEO satellites. Using zero-copy kernel-bypass memory buffers, PSA 2.0 aggregates these streams into a single clean TCP/QUIC connection with zero re-ordering jitter.

Key Functions

• Final user plane anchor point terminating multipath 6G cellular and non-3GPP sessions
• Zero-copy memory buffering delivering line-rate packet egress to external data networks
• Re-ordering and deduplicating packets received across disparate cellular and satellite links
• Executing enterprise firewalling and charging data collection at 100+ Gbps line rate
• Support for IPv4, IPv6, Ethernet, and unstructured 6G packet data unit types
