Analyst/Programmer/System Manager at the Dutch Library for the Blind
This is were I learned programming and understanding computers. I used C and Unix quite heavily. Worked on programs for the lending system, that was an in-house development. Did a complete rewrite of the lending system, did a transfer to Unix V7, wrote the complete documentation of the lending system and installed the system at the Royal Library for the Blind in Copenhagen. Started working at the Catalogue system, that was to be shared between the four Libraries for the Blind in The Netherlands |
| 1985 - 1997 | SARA - Stichting Academisch Rekencentrum Amsterdam (Academic Computing Services Amsterdam) |
| 1985 - 1986 |
Started as a systems programmer, where I worked on the ModComp front end systems for the CDC Cyber mainframes. They were used as the asynchronous terminal drivers and for a line editor. My task was adaption of the editor system to communicate with more than one terminal driver. Programming language used was Coral66 and ModComp assembly language.
I also extended the editor itself, which was ahome-grown system, with the use of meta-characters resembling the use in Unix systems. |
| 1986 - 1987 |
In May 1986 I joined the networking group.
I worked on an application level gateway for filetransfers based upon a modified kernel for VAX/VMS. This was a joined project with CERN (Geneva), INFN(Rome) and RAL(Oxford). The gateway could transfer files between Blue Book, CERNet, DECnet, FTP and RHF (CDC network) protocols. Afterwards I worked on an application level mail gateway, to accomodate email application on the Cyber CDC mainframes. This mail gateway was build on an VAX/VMS system. |
| 1987 - 1994 |
In November 1987 I became head of the networking group. My main tasks remained technical in nature.
In 1988 SARA got a contract with SURFnet, the provider of networking services to the educational and research community in The Netherlands. This contract was about the management and deployment of their new TCP/IP service. The networking group has since then done the operational management of the SURFnet IP network, including various European and Transatlantic connections. Over the years we have grown and expanded the national network from 64 Kb/s X.25 circuits to 34 Mb/s leased lines and ATM circuits, offering a fully resilient, high speed network to over a 200 customers. |
| 1991 - 1993 |
I was quite heavily involved in the Ebone project. This was a joint project between various European IP providers, mainly from the Educational and Research community, to build a European IP backbone, awaiting commercial offerings.
Ebone was the first Europena network to employ BGP (first BGP-3, later on BGP-4) in an fully operational environment. As one of the participants in the Ebone project I developed a thourough understanding of the routing and addressing issues in the Internet. I also did some work on statistics gathering, measuring traffic flows over the Ebone network and the SURFnet network. |
| 1994 - 1997 | With a reorganisation at SARA the networking department ceased to exist as a separate department. My function became network consultant, training and supporting the IP management group, advising customers on (secure) Internet connections and participating in the IP management, mainly focused on complex routing issues and the introduction of new services, like the Amsterdam Internet Exchange and the deployment of ATM in the national network, in customer connections, and in local area networks. |

General Electric Information Services International Inc.
On september 1st, 1997 I started as consultant networkconfiguration with GEIS International. My tasks are to provide second line support for the management of the European part of the General Electric Intranet. This Intranet currently contains around 800 Cisco routers of all types, running IP, IPX, Decnet, and various IBM protocols. The GE Intranet provides data communication for all GE businesses in Europe, and their customers or external connections. I make network designs for changes or additions to the existing network, for networks of new or acquired GE components and for connections to clients of General Electric Information Services. These designs can be the WAN connections as well as the LAN infrastructure in case of shared services between GE Businesses, where we provide a switched infrastructure. I participate in the setup and management of the General Electric Internet connection in Europe. I am part of the team that is resposible for network security and design Firewalls for connections to third parties. |
