The infrastructure contains security services for authentication, authorization, and integrity.
Safety services constrain resource usage and isolate unrelated activities.
With the key components of the network thus securely smart-enhanced, not only can we begin to address current management concerns but we can define a distributed monitoring and control system based on an active management infrastructure. An active management paradigm is required because only active management can efficiently provide the flexibility and scaling behavior necessary to cope with internetworks growing in size and diversity. Dynamic management of a dynamic internetwork can only be done via smart-enhanced components. The Active Networks technology required by such components must be designed for use by monitoring and control integrated at the lowest system level of the components. The necessary performance cannot be guaranteed any other way.
