With Lead Up, I mostly worked with telcos in planning and deploying systems supporting fault reporting, performance analysis and billing data collection. HP OpenView Network Node Manager and Operations were used as a platform for some of these systems. Other systems and analysis included use of Perl and other scripting. Subsequent to Lead Up, I have worked on deploying OpenView Operations in a telco.

Since 2002 I developed IN-network configuration applications for AAPT using Visual Basic, ASP and Access databases.

In 2001, I worked with HP in Colorado as a consultant in designing systems for managing VoIP hardware in conjunction with Cisco, and large scale internet data centers.

From 1993 to 2001, I worked on SNMP agents and NMS systems for the management of ATM networks. Implementations have been based on ATM Forum and IETF derived standards such as RFC 1695/2515 (AToMMIB) and M3 interfaces as well as proprietary interfaces. The NMS systems included advanced prototypes using early releases of MPOA, NHRP and PNNI management in ATM. Some implementations were based on HPs OpenView network management platform with SNMP agent development based the use of CiTRs MIB Master SNMP toolkit. David is active in the IETF, and attended IETF meetings, introducing RFCs jointly developed with NEC Japan. For NEC USA we developed an ATMF M3 interface providing a Customer Network Management view into ATM network service provided by a NEC Model 10 backbone.

In 1999, I was seconded to Astracon to work on IP-VPN network designs and CMIP based ATM switch configuration.

Prior to this I was involved as a project architect for the Australian and Overseas Telecommunications Corporation's Fastpac Network Services implementing a network management system for the AOTC Fastpac 2 Mb/s service. This was developed on the OpenView windows and SNMP-DM APIs.

I was also involved in research into finding applications that would suit a massively-parallel supercomputer (MasPar) in addition to supporting about 80 users throughout Australia. This computer was used for neural network and database research. I run training courses on this technology for the users.

An earlier project was the A-Series SQL*Star product for the Australian Centre for Unisys Software (ACUS). This project involved porting Oracle products to the Unisys A Series platform to enable A Series systems to participate in SQL*Star networks. On this project David worked with a real-time system and large databases, response time performance analysis and developed quality control methods.

Before joining CiTR, I was a software specialist for Digital Equipment Corporation in Brisbane and Melbourne, developing custom technical applications for customers. This involved tuning large databases, creating real-time applications, and generating quality control and test plans. Some particular specialisations were Ada and C languages, CASE tools and telex/communications software.
