Defining intelligent network services in a multivendor distributed environment

The author presents the potential for synergism between silicon compilation used in the application specific integrated circuit (ASIC) design process, and the intelligent network service defining process, including creation, evaluation, and execution. The synergism is explored to solve the problem of switch programmability in future intelligent networks. A three-domain framework of the intelligent network service defining process in a distributed heterogeneous environment has been prototyped. The front-end of this framework includes the user interface, and the knowledge-based engineering environment (KEE) tool. A behavior-level intelligent network service description defined by objects and object classes is the input of the front-end process. The output of the front-end process is the KEE internal construct. Given the KEE internal construct, a service script translator (SST) written in LISP is used to generate the parameterized service/operation scripts in VXM formats. The SST is the back-end of the intelligent network service defining process. Service/operation scripts are used to control the execution of applications over a distributed heterogeneous network
