Software resiliency is enabled for guest network functions (GNFs) in the in-chassis Junos Node Slicing model. Resiliency enables the software to recover from certain types of failures. The in-chassis model allows all Junos Node Slicing components, such as Juniper Device Manager (JDM), base system (BSYS), as well as guest network functions (GNFs), to run within the Routing Engine of the router.
