René Jorissen’s Summary

Every day I do work related to IP networking. IP networking covers a broad range of technologies, like switching, routing, security, mail relaying, proxy servers, IPSec / SSL VPN, IP telephony, anti-virus, anti-spam and so on.

There is no focus on a specific hardware supplier or vendor. I work with many different hardware and software. Some known vendors are Cisco Systems, Juniper Networks, HP ProCurve, 3Com, eSafe, Microsoft and more.

I have experience with different kind of platforms and can therefore manage myself in multiplatform environments, including Microsoft Windows, GNU/Linux, Mac OS X and Cisco IOS.

Currently I am Cisco CCNP certified and I am trying to get a Cisco CCVP certification. I hope to pass for the CCIE certification one day.

René Jorissen’s Specialties:

Everything related to IP networking is some kind of speciality.
