Abstract Over the last five years, open source software has moved into mainstream areas such as Internet and financial applications, with software such as Linux and Apache Web Server now supporting mission-critical operations. Open source software can offer both cost reductions and improvements in software quality. However, the uptake by incumbent telecommunications providers has been virtually zero, instead focusing on major commercial-off-the-shelf (COTS) packages, due to a mixture of prior strategic investments and perceptions over open source risks. This paper addresses the scope for use of open source software in telecommunications operational support systems (OSS). Firstly, the technical scope for open source software is addressed, covering the maturity of available open source software components, and the ways in which these components can have an impact on OSS software architecture. Secondly, the commercial aspects are presented, covering benefits, commercial models and risks. An OSS life cost comparison of open source versus COTS software is included. Thirdly, a test OSS created by BT using primarily open source software, combined with OSS standards to provide a minimum cost base, is presented and analysed. The paper concludes with a statement on the potential for the use of open source software in OSS, and suggests possible next steps. [ABSTRACT FROM AUTHOR] |
