act Syntax Notation One (ASN.1) can be used as a common substrate for representing active programs. An active networking framework, using ASN.1 whereby any active network solution can be deployed independently of the active network element's architecture is discussed. In this paper, we demonstrate the independent representation using a simple procedural language. This technique however is language independent and can be extended to cover any language including all those currently used in active networks. ASN.1 is ideally suited to this purpose since it was originally conceived as a language for the representation of programs and data types in protocol data units (PDUs). This solution maintains security, mobility and efficiency.
