Wasm Sandbox
WebAssembly Micro-Sandbox for Core Network Functions
A lightweight, secure, cross-platform execution environment allowing untrusted enterprise microservices to run directly inside 6G core nodes.
Technical Explanation
Traditional containerization (like Docker or Kubernetes pods) introduces memory overhead and slow start-up times (hundreds of milliseconds). 6G core nodes leverage WebAssembly (Wasm) micro-sandboxes. Wasm modules spin up in microseconds with sub-megabyte memory footprints, providing mathematical memory isolation (sandboxing) that permits third-party tenant algorithms to execute directly within the core network without security risks.
Key Functions
- Sub-millisecond cold start times enabling instantaneous serverless function execution
- Strict memory isolation preventing untrusted code from accessing adjacent network functions
- Near-native CPU execution speeds across heterogeneous x86, ARM, and RISC-V architectures
- Compact bytecode binary size (<1 MB) ideal for resource-constrained satellite nodes
- Standardized WebAssembly System Interface (WASI) bridging network hardware APIs
