Network Management
Dr. Lavian, a telecommunications expert witness and internet expert witness, offers network management consulting services involving Network Management Systems (NMS), network device management, and network management of routers, switches, gateways, firewalls, MIBs, and SNMP. Network management includes the processes, tools, and applications used by the network administrator to administer, operate, troubleshoot, and maintain a communication network infrastructure. The acronym FCAPS is the OSI/ISO model for Network Management commonly considered to include the following five domains:
- Fault.
- Configuration.
- Accounting.
- Performance.
- Security
Network Management Technologies
Network management is the process of monitoring, configuring, and maintaining the performance and security of a computer network. Network management systems (NMS) are software applications that help administrators manage and monitor the health and performance of a network. One standard protocol used in NMS is the Simple Network Management Protocol (SNMP). SNMP sets standards for communication with devices on a network, such as routers, switches, and servers. It allows administrators to remotely monitor and manage network devices by sending and receiving messages, known as SNMP traps and SNMP requests, between the NMS and the network devices. SNMP can monitor the performance and status of devices and configure and update their settings. It is used in monitoring and maintaining computer networks and the internet.
