Working for a fortune 500 Company, a high-profile Data Centre, my main role is management and timely resolution of critical network Incidents, Changes and network re-design. As a Network Analyst my duty is to carry out network risk assessments, security tests, high availability planning, Disaster recovery, Major network designs/ re-designs, network implementations and installations, Maintenance and incident management. My daily role involves configurations of various network devices (switches, routers, firewalls VPN concentrators, load balancers etc) from vendors like Cisco, Nokia/checkpoint, Juniper, F5 etc. I constantly get involved in major network projects where I liaise with various internal departments and 3rd party suppliers/ providers. Majority of the time I spend on network security troubleshooting, using concepts like packet-tracers, packet-capture/ trace, tcpdump, fwmonitor, Ethereal etc.

As part of a team, split over 4 shifts, I am responsible for the monitoring of the hardware and the network architecture of our Sungard High Availability customers spread over five Sungard HA sites across Greater London; this is accomplished using remote access via SSH and Terminal Services and is monitored by EHealth. All customers are split into two groups, Managed and Colo (Co–Location), and the level of support is dependant of what has been agreed within the Service Level Agreement. The majority of our customer environments run on a Windows based Operating System, such as; Win2k/NT/2003, there are also environments which utilise the various flavours of UNIX (Sun Solaris 10 and HP UX). A number of our customers also use various versions of Linux (Redhat, Suse and Ubuntu), so having an understanding of these systems is a must for effective troubleshooting. A thorough understanding of TCP/IP is required in my position as this assists me when investigating issues where I have to log onto Cisco/Nokia Equipment and diagnose the problem before it gets escalated to the Networks/Open Systems team. Administration also plays a large part in my role, this includes; documenting all issues, Task/Change requests and backup management. All backups are controlled via Netbackup, so a good understanding of this application is vital to the role. I also log and action calls in our Remedy/Netcool Webtop call logging software.
