What are active networks?

Radical design paradigm which advocates carrying programs
+ data as part of a packet. Routers are said to be active
in such a network since, each of the routers will be executing
the code in the packets instead of just forwarding or routing
them as in a conventional network. The routers should support
secure execution of code without which the entire infrastructure
could fail. Techniques have been provided for securely fingreprinting
the code to prevent spoofing and malicious code execution.

Largely not adapted in the real networks due to the huge change in
design.
