Terminal Multi-Path BBR Controller

Technical Explanation

6G terminals maintain concurrent active links across multiple wireless technologies (6G sub-THz, 5G mid-band, Wi-Fi 8, and LEO satellite). The Multi-Path BBR (Bottleneck Bandwidth and Round-trip propagation time) controller measures model-based capacity and queuing delay on each path in real time. Rather than relying on loss-based congestion control, it allocates packets to match the instantaneous bottleneck bandwidth of each interface, avoiding bufferbloat and packet reordering latency.

Key Functions

• Aggregates data throughput simultaneously across 5G, 6G, Wi-Fi, and satellite
• Prevents bufferbloat and packet drop by modeling bottleneck capacity
• Maintains zero-interruption transport sessions during individual link loss
• Reduces tail latency for interactive video streaming and cloud gaming
