| Description: |
The goal of proactive network management is to prevent problems that can
happen in networks and avoid them from having an impact on the service
offered to users, by detecting them before they occur. Formal description techniques, and LOTOS in particular, can be used in proactive network management for specifying the behaviour of "proactive agents", i.e. processes that control and analyze network traffic. In order to ease the elaboration of new proactive agents, a library of re-usable components has been developed at UFSC. This library (named "bibLOTOS") contains LOTOS types and processes that can be used as building blocks for specifying proactive agents, together with informal descriptions, C code and transition systems generated by the CADP tools. The library itself is implemented as a Microsoft Access database. The bibLOTOS library has been used to specify a proactive agent responsible for controlling traffic in a network. The specification was then exhaustively simulated using the CADP tools, then interactively simulated, executed, checked for deadlocks, and compared to the service graph modulo observation equivalence. |
| Conclusions: |
The specification task is greatly helped by the use of bibLOTOS
predefined constructs. The CADP tools are useful for checking the
correctness of the specification built with the predefined constructs.
