Case Study #1 - Product Development
The Client: A United Kingdom based development of photonic network equipment. It aimed to become the first group worldwide to develop and install all-optical packet switching platforms. The first step was an all-optical cross-connect capable of scaling from a modest to a mammoth size.
The Challenge: Reliable and efficient software and firmware was essential to realising this goal. Among the functionality to be provided by software at various levels was:
- Control of connections and equipment settings
- Control of end to end optical paths and performance monitoring
- Fault localisation
- Protection switching
- Alarm, event and performance logs and reports
The Solution: Thanks to our in-depth experience in the telecommunications sector, including fibre opticals and conventional cross-connects and switches, LeoTel Software Systems was able to provide a complete software solution at a competitive price. Object Orientated Design was used throughout. The management software was designed using Rational Rose and was implemented in C++. A hardware simulator was developed to assist in testing. The craft interface was implemented in Java. The ability to inter-work with third-party applications, such as billing systems and other business management functions, was another priority. To provide maximum flexibility an upward Q3 interface was designed and implemented.
