New Service Verification
As networks develop, service providers (SPs) face fierce competition. Each SP intends to keep existing users and attract more users in the existing network environment. Adding new services helps SPs remain competitive. However, deploying unverified new services directly on network devices poses a security risk. The virtual system (VS) technique, which isolates services, can be used to prevent this risk.
As shown in Figure 1, new services are deployed on VSs to verify the services and avoid security risks. This deployment makes full use of resources and does not affect the existing services.
