Network Engineers can wear many different hats. I believe the more “Traditional” Network Engineers mainly work on devices such as Routers, Switches, Firewalls, Wireless Access Points and Controllers, Load Balancers, Intrusion Detection and Prevention Systems as well as some server maintenance involving virtualization and network management software. Next we should discuss the overview of the differences between Network Engineering and Administration. Keep in mind I am just talking from an industry general view/standpoint. Some companies may not differ between the 2 titles. Engineers and Admins tend to share a lot of responsibility when it comes to maintaining and troubleshooting a network. The dividing line seems to be in the design/installation area with the bulk of this work generally being done by the more “experienced” engineers. Admins usually fall under the NOC (Network Operations Center) which in large companies/agencies is usually staffed 24x7x365. I have also seen the difference broken down into tiers when it comes to troubleshooting escalation. Network Admins usually fall in the Tier 1-2 range with Engineers
