Unified Control Plane Bus

High-Speed Protobuf Binary Micro-Bus

The ultra-fast binary communication bus connecting all co-located 6G core functions on a single server rack using shared memory and zero-copy IPC.

Technical Explanation

When core network functions run on the same physical server or within the same data center, routing messages over standard network sockets and TCP stacks introduces unnecessary serialization delay. The Unified Control Plane Bus utilizes shared memory (POSIX shm) and Inter-Process Communication (IPC) to pass binary Protobuf messages between AMF, SMF, and PCF instances in nanoseconds, eliminating networking protocol stack overhead entirely.

Key Functions

  • Nanosecond-level inter-process communication (IPC) between co-located core functions
  • Zero-copy shared memory message passing eliminating network stack serialization
  • Binary Protobuf encoding delivering 10x faster parsing compared to legacy JSON
  • Slashing control plane signaling latency for ultra-rapid device connection setup
  • Dynamic fallback to network sockets when functions are distributed across different servers
