Technical Knowledge of Alexander H. Hackenberg

Of course I have very good knowledge of basic networking:

OSI seven layer model, ethernet, token ring, bridging, ATM, X.25, Frame-Relay, Serial lines, etc.

Also Detailed knowledge of the TCP/IP protocol suite:

IP, TCP, UDP, Routing protocols (RIP, (E)IGRP, OSPF, IS-IS, BGP4, policy routing), DNS, BootP, IP Multicasting, HTTP, SNMP, etc.

Because of my working history I know pretty much about Networking in traditional IBM mainframe environments:

SNA, VTAM, NCP, X.25, SDLC, APPN, etc.

When I was working for PSK I was also responsible for security issues for Cisco routers and switches as well as for the firewall connecting the bank to the internet. Therefore I still have good knowledge about network security.

Of course over all these years I build myself pretty good knowledge about several operating systems including Windows (v3.11 up to windows 7 and NT Server up to Server 2008), Unix (eg. AIX), Linux (Suse, Ubuntu) and Novell Netware and the IPX/SPX protocol suite.

In the last couple of years I was also into 'new' techniques like MPLS and IPv6, where IPv6 is a real hobby of mine and I really hope that we will have it enrolled rather sooner than later (no more NAT - horray!).

Since about 2001 I got also invoved into load balancing, first with the Cisco CSS then with the CSM and the ACE. Not only that I teach the load balancing classes but I also was taking part in several consultings about the CSM and the ACE.

Since 2005 I got myself more and more into storage systems (NAS, SAN, Fibre channel fabric, etc.) involved, and so it came that I also teach Netapp classes and courses about the Cisco storage switches now.

Last but not least I work intesively with Data Center Networks since 2008. That includes Layer 2 Networks in Data Center(s), Virtualization of Networks (inclusive virtual firewalls, load balancer, etc.) and Server (VMWare and Blade Server) and the UCS technologie of Cisco Systems.
