CFN
Compute-First Networking / Compute-Aware Traffic Routing
A dynamic routing protocol that routes user requests simultaneously based on network path latency AND real-time computational load on target servers.
Technical Explanation
Traditional IP and BGP routing only consider network path distance or bandwidth, frequently routing users to overloaded compute servers simply because the network path was shortest. 6G Compute-First Networking (CFN) integrates compute telemetry (CPU load, GPU availability, memory capacity, queue depth) into routing header advertisements. The 6G core routes incoming XR and AI workloads to the optimal server based on combined network latency plus compute execution time.
Key Functions
- Joint optimization of network transmission delay and target compute server execution time
- Dynamic advertisement of compute resource metrics inside BGP / SRv6 routing headers
- Instantaneous load-balancing across edge data centers, roadside servers, and central clouds
- Steering heavy AI inference tasks to the closest GPU/NPU cluster with free capacity
- Elimination of compute bottlenecks for interactive holographic and tactile applications
