Network administrator

A network administrator is an individual that is responsible for the maintenance of computer hardware and software systems that make up a computer network including the maintenance and monitoring of active data network or converged infrastructure and related network equipment. Network administrators are generally mid-level support staff within an organization and do not typically get involved directly with users. Network administrators focus upon network components within a company's LAN/WAN infrastructure ensuring integrity. Depending on the company and its size, the network administrator may also design and deploy networks.[1] The actual role of the network administrator will vary from place to place, but will commonly include activities and tasks such as network address assignment, management and implementation of routing protocols such as ISIS, OSPF, BGP, routing table configurations and certain implementations of authentication (e.g.: challenge response, etc.). It can also include maintenance of certain network servers: file servers, VPN gateways, intrusion detection systems, etc. In smaller organisations, network administrators may also be technically involved in the maintenance and administration of servers, desktop computers, printers, routers, switches, firewalls, phones, IP Phones, personal digital assistants, smartphones, software deployment, security updates and patches as well as a vast array of additional technologies inclusive of both hardware and software.
