ACTIVE NETWORKS: SAFETY ISSUE

Safety and security ar two most important properties of a system. A safe system provides protection against error of trusted users, meanwhile a secure system protects against error introduced by untrusted users. In this situation, high requirement for rapid service creation have stimulated the development of programmable network infrastructure where end users or service providers can customize the properties of a network infrastructure while it continues to operate. The ability on customization of network infrastructure properties is called active networks[2]. But the main concern of potential users of such systems is their reliability and most specifically their safety and security. As for this paper, the scope of the research is towards the safety issues involved in the active network architecture. A variety of proposals for exposing some control of network infrastructure have been made. Priority has been given on exposing this shared infrastructure to users must preserve some expectations of reliability while allowing the infrastructure to be multiplexed to derive the economics advantages of sharing. In this paper, attention has been given to one of this proposal, discuss further on the plus and minus point of it and also the future suggestion towards the better performance of the active networks.
