Reverse Engineering of Complex Legacy Telecommunication Systems

Kurzfassung: Reverse and reengineering of large and complex software systems is a difficult task. As a result, many methods and tools for reverse and reengineering have been developed so far. However, the work in this field has concentrated on sequential, and untimed systems, mainly for business applications. The majority of the approaches deals with decomposing monolithic systems, decoupling u...

E-CARES Research Project: Understanding Complex Legacy Telecommunication Systems

There are many reasons for reverse engineering or reengineering legacy systems. To date, many approaches concerning re-engineering of legacy systems have been made. The majority of these approaches are dealing with systems in the field of business applications. This paper describes the work performed for the E-CARES project so far. This project is concerned with understanding and re-structuring...

State Oriented Program Comprehension in legacy distributed telecommunication systems

Distributed telecommunication systems consist of several programs that spawn independent but collaborating processes during their execution. These processes are implementations of state-based systems. Understanding programs is a pre-requisite for the effective maintenance of a software system. Program comprehension aims at helping software maintainers understand programs by acquiring knowledge ...

The CAMOUFLAGE Project - Introduction of TINA into Telecommunication Legacy Systems

The CAMOUFLAGE Project is a national german research initiative led by the Deutsche Telekom. It aims at the provision of a TINA conform distributed processing environment based on existing legacy telecommunication systems. The envisaged target architecture is a switched ATM network deploying B-ISDN. Using an integrative approach a mutual stimulation between the TINA technology and the BISDN tec...
