This report describes how different standardized management protocols can be incorporated into telecom applications with little or no impact on the overall software architecture. It presents a framework providing the necessary flexibility needed when different standardized management protocols have to coexist along side each other, or need to be interchanged due to changing system requirements.

The report shows there is a mapping from this framework to management protocols commonly used in telecom applications, namely SNMP, Corba and HTTP. OSI based management is also superficially discussed. The framework has been developed in Erlang, but can be used in any high level functional programming language.

Keywords: standardized management protocols, telecom applications, network management, Corba, SNMP, HTTP, Erlang
