Delegation model supports effective and highly reliable network management. It reduces traffic overhead caused by transmission of management informations. In this model, management scripts can be composed by the designers of managers, these are delegated to agents. Delegation models support effective distribution of management functions among managers and agents. Therefore, various functions are needed to create and delegate management scripts. In this paper, we design simple script language and implement script interpreter for efficient network management. And, we define script management functions and services. Moreover, we present manager/agent models and algorithms for script management. As an implementation environment, the ISODE services are ported. The methods employed for the implementation are also described.
