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, and consider what the future may hold for these professionals.
