Integrity methodology for interoperable environments
Ognjen Prnjat, L. Sacks · IEEE Communications Magazine · 1999
Modern telecommunications systems are becoming increasingly complex, in both their internal construction and the degree of interconnectivity-and interdependence-between systems. This situation is exacerbated by regulatory demands for operator interworking and requirements for high-quality delivery to users. In this context, the crucial issue is the ability of systems to retain their operational state of high integrity. The number of integrity issues in such systems is vast, and these issues must be understood and managed throughout development, testing, interconnection, and maintenance. This article presents a framework for analyzing the integrity features of telecommunications systems, and elaborates on integrity-preserving policies that can be applied during system development and deployment. Moreover, a description of a case study based on ACTS project TRUMPET (DGXIIIB, AC112) is given.
