¶ … competitive, fast-paced business world, a network failure can be disastrous. The pressure placed on network administrators to fix issues immediately is daunting; these important players need all the tools they can get to troubleshoot, prevent, and repair problems. Network administrators must remain vigilant and work constantly to monitor for interface or host failures, detect route flapping or intrusions, perform LAN segment switches or bandwidth adjustments, and monitoring overall performance for Service Level Agreements (SLAs). The International Organization for Standardization (ISO) has grouped these tasks into five main management categories: performance, fault, configuration, accounting, and security. Successful network administration across these categories requires sophisticated tools and technology, and as with other aspects of computer networking, network administration is based on protocols. The most popular network management protocol in place today is the Internet SNMP (Simple Network Management Protocol), although this standard is far from simple. In fact, this protocol is just one aspect of the overall management operation. Also known as the Internet-Standard Management Framework, the overall operation is based on four main components: the Management Information Base (MIB) objects and modules, the SMI (Structure of Management Information) data definition language, the SNMP protocol, and security and administration capabilities. (Kurose and Ross) Staying on top of so many important operations is a daunting task even for seasoned administrators, and the demand for these talented professionals is growing. The question is: how do they do it? This essay will explore in more detail what takes place during the day of a network administrator, suggest ways to increase the number of students choosing network administration as a career,...
Apparently, the stress of the job is such that this important breed of computer scientists is eager to vent and share their experiences. Overall, from reading these accounts, it appears that a typical network administrator works anywhere from 8 to 16 hours a day, with responsibilities including the following:
Check the uptime monitors on all the servers
Check client emails
Troubleshoot any problems
Plan, coordinate, research, and ensure network security
Perform a DNS edit before performing any repairs
Sync data on database servers
Check sites
Reply to threads
Interact with users
Check for new submissions
Perform scheduled maintenance
Perform System upgrades
Respond to client requests
Analyze historical data and plan for the future
But this is assuming everything runs smoothly. If there are any significant problems, all the functions above are further complicated, and the administrator will have to keep working until every issue is resolved .
Based on the importance of computer networks across the world today, it is easy to see why these professionals are in high demand despite the global recession; based on the obvious stress of the job, it is easy to understand why recruitment efforts are on the rise. According to American Public Media and the Bureau of Labor Statistics, the job number percentage in this subfield will increase by nearly 30% over the next ten years in the United States alone. So how can teachers and business…
